BEST MODE FOR CARRYING OUT THE INVENTION Embodiment modes of this invention will be hereinafter described. EMBODIMENT MODE 1 A configuration of a film forming apparatus in this invention will be described by use of FIG. 1. FIG. 1 is one example of a cross-sectional view in the film forming apparatus of this invention. On the occasion of carrying out film formation by a deposition method, it is preferable to use a face-down system (also called as a depo-up system), and a substrate 10 is set with a film formed surface downward. A system, in which film formation is carried out with a film formed surface of a substrate face downward, is called as the face-down system, and according to this system, it is possible to suppress attachment of dust. As shown in FIG. 1, in contact with the substrate 10, heating means, here, a heater is disposed on a substrate holder 12. By heating means, it is possible to set temperature of the substrate to 50-200� C., preferably, 65-150� C. In addition, the substrate 10 is fixed by being sandwiched by metal masks (not shown in the figure), by a permanent magnet which was built in the substrate holder. In addition, on a level block 18 which was disposed in a film forming chamber, deposition cells (also called as deposition holders) 13, which are also capable of being heated to temperatures which are different from each other, are disposed. In passing, a deposition source is disposed so as to be opposed to the substrate. Here, shown was an example in which the substrate was fixed by being sandwiched by metal masks, by use of the permanent magnet, but it may be fixed by a holder. Here, the deposition source is composed of the deposition cells 13, a container which accommodates an organic compound (a crucible, a deposition board, etc.), a shutter 14, heating means for heating the organic compound, and a heat insulating material for surrounding a periphery. As the heating means, a resistance heating type is standardized, but a Knudsen cell may also be used. In addition, to the film forming chamber, coupled are a gas introduction system which introduces material gas by several sccm into the film forming chamber at the time of deposition, and a gas introduction system which makes an inside of the film forming chamber at normal pressures. As the material gas, used are one kind or plural kinds, which were selected from monosilane, disilane, trisilane, SiF4, GeH4, GeF4, SnH4, CH4, C2H2, C2H4, or C6H6. In passing, it is desirable to make no material gas flow from a gas introduction port to a gas discharge port by the most direct way. When a space surrounded by a chamber wall 11 is depressurized to 5�10−3 Torr (0.665 Pa) or less, preferably, 1�10−3 Torr(0.133 Pa) or less, by depressurizing means (a turbo molecular pump 16 or a vacuum pump such as a dry pump and a cryopump 17), and the organic compound in an inside is heated up to sublimation temperature by heating means which was disposed in the deposition cell (resistance which is generated on the occasion that a voltage was applied (resistance heating)). It is evaporated and deposited on a surface of the substrate 10. By introducing a material gas with several sccm on the occasion of this deposition, a component of the material gas is included in a film. In passing, in FIG. 1, shown is such an example that co-deposition is carried out with one cell being inclined, so that an evaporated first material 15 a and an evaporated second material 15 b are mixed, and further, introduced material is mixed to form a film. The co-deposition is referred to a deposition method in which different deposition sources are heated and evaporated at the same time, and different materials are mixed in a film forming stage. In addition, the substrate holder 12 is rotated so as to equalize a film thickness, on the occasion of deposition. In passing, it is assumed in this specification that the surface of the substrate includes the substrate, and a thin film which was formed on the same, and here, it is assumed that an anode or a cathode is formed on the substrate. In passing, the shutter 14 controls deposition of an evaporated organic compound. In short, when the shutter is opened, it is possible to deposit an organic compound which was evaporated by heating. Further, one or a plurality of other shutters (e.g., a shutter which covers a deposition source during a period until sublimation from the deposition source is stabilized) may be disposed between the substrate 10 and the shutter 14. In passing, it is desirable to heat and evaporate an organic compound prior to deposition, and to be able to immediately start deposition once the shutter 14 is opened at the time of deposition, since film forming time is shortened. In addition, in the film forming apparatus in this invention, it becomes possible to form an organic compound film having a plurality of functional regions in one film forming chamber, and a plurality of deposition sources are disposed in accordance with it. In addition, disposed is an anti-attachment plate 19 for preventing an organic compound from being attached to an inner wall at the time of deposition. By disposing this anti-attachment plate 19, it is possible to have an organic compound, which is not deposited on a substrate, attached. In addition, the film forming chamber is coupled to a plurality of vacuum pumping processing chambers which evacuate an inside of the film forming chamber. As the vacuum pumping processing chamber, it is equipped with a magnetic levitation type turbo molecular pump 16 and a cryopump 17. By this, it is possible to set ultimate vacuum of the film forming chamber to 10−5-10−6 Torr. In passing, it is designed to stop the cryopump 17 after vacuum pumping was carried out by the cryopump 17, and to carry out deposition over flowing material gas with several sccm, while carrying out vacuum pumping by the turbo molecular pump 16. After deposition was finished, inert gas is introduced while discharging air by the turbo molecular pump, to increase a pressure to some extent, and remaining material gas is discharged from the film forming chamber, and high vacuum pumping is carried out again. Finally, a deposited substrate is taken out from the film forming chamber to a load chamber while keeping vacuum. In addition, as a material which is used for a chamber wall 11, since it is possible to lessen sorbability of an impurity such as oxygen and water, by lessening its surface area, aluminum and stainless (SUS) etc., which were changed to a mirror surface by applying electrolytic polishing, are used for an inside wall surface. By this, it is possible to maintain a degree of vacuum in an inside of the film forming chamber to 105-10−6 Torr. Also, a material such as ceramics, which was processed so as for air holes to get fewer in the extreme, is used for an inside member. In passing, it is preferable that these are materials having such surface smoothness that center line average asperity becomes 3nm or less. If the film forming apparatus shown in FIG. 1 is used, it is possible to form a high-density film by intentionally introducing material gas at the time of film forming, and by having a component of the material gas included in an organic compound film. By having a component of a material gas included in an organic compound film, it is possible to block an impurity such as oxygen and moisture which causes deterioration from being intruded, diffused in a film, and to improve reliability of a light emitting device. For example, when monosilane gas with several sccm is introduced into a film forming chamber in which deposition is going on by evaporating an organic material, together with the organic material which is evaporated from a deposition source and proceeding to a substrate, SiH4, which is floating in the film forming chamber is taken in an organic film. That is, a gap of organic material molecules with a relatively large particle radius is to be filled in with SiH4 with a small atomic radius as it is, or with SiHx, and it is possible to have it included in an organic film. During a period of deposition, a deposition source is heated to a level of 100� C., but decomposition temperature (decomposition temperature under atmospheric pressure) of monosilane is approximately 550� C., and therefore, it is not decomposed. According to an organic material to be evaporated, there is also such a case that it is reacted with SiH4, or SiHx to form a compound. In addition, since oxygen (or moisture), which slightly remains in the film forming chamber, is captured to generate SiOx, it is possible to reduce oxygen (or moisture) which is a factor for deteriorating an organic material in the film forming chamber and in a film, and accordingly, it is possible to improve reliability of a light emitting device. In addition, generated SiOx may be included in a film as it is. It is conceivable that, when there is a gap of organic material molecules in a film, it is easy for oxygen to enter into the gap, and deterioration is generated. Therefore, since it is only sufficient to fill in this gap, it is possible to improve reliability of a light emitting device, even by using SiF4, GeH4, GeF4, SnH4, or hydro carbon series gas (CH4, C2H2, C2H4, C6H6 etc.). In passing, as the above-described organic material, it is possible to point to α-NPD(4,4′-bis-[N-(naphthyl)-N-phenyl-amino]biphenyl), BCP(basocuproine), MTDATA(4,4′,4″-tris(N-3-metylphenyl-N-phenyl-amino)triphenyl amine), Alq3(tris-8-quinolinoaluminum complex) and so on. Hereinafter, by use of the film forming apparatus of FIG. 1, shown is one example of a fabricating procedure of a light emitting device having an anode, an organic compound layer which is in contact with the anode, and a cathode which is in contact with the organic compound layer. Firstly, a substrate, on which an anode was formed, is carried in a carry-in chamber (not shown in the figure). As a material which forms the anode, a transparent conductive material is used, and it is possible to use an indium/tin compound, zinc oxide and so on. Then, it is transferred to a film formation pretreatment chamber (not shown in the figure) which was coupled to the carry-in chamber (not shown in the figure). In this film formation pretreatment chamber, cleaning of an anode surface, oxidation treatment, heat treatment etc. may be carried out. As the cleaning of the anode surface, irradiation of ultraviolet rays is carried out in vacuum, and the anode surface is cleaned. In addition, as the oxidation treatment, it may be irradiated with ultraviolet rays in an atmosphere including oxygen, while being heated with 100-120� C., and it is useful to such a case that the anode is an oxide like ITO. In addition, as the heat treatment, heating with heat temperature of 50� C. or more, at which a substrate is sustainable in vacuum, preferably, heating of 65-150� C. may be carried out, and removed is an impurity such as oxygen and moisture attached to the substrate, and an impurity such as oxygen and moisture in a film formed on the substrate. In particular, since an EL material easily gets deteriorated by an impurity such as oxygen and water, it is useful to heat in vacuum prior to deposition. Then, the substrate, for which the above-described pretreatment was finished, is carried in the film forming chamber without contact with atmospheric air. In the film forming chamber, the substrate 10 is set with a film formed surface downward. In passing, it is preferable that vacuum pumping is applied to an inside of the film forming chamber before the substrate is carried in. Vacuum pumping means, which is disposed so as to be coupled to the film forming chamber, vacuates a level of 1 Pa from an atmospheric pressure by an oil-free dry pump, and vacuates a pressure more than that by the magnetic levitation type turbo molecular pump 16. Further, in the film forming chamber, for the purpose of removing moisture, the cryopump 17 is disposed in parallel. By doing this, a degree of vacuum up to 1�10−6 Torr is realized. On the occasion of carrying out vacuum pumping an inside of the film forming chamber, it is possible to remove absorbed water and absorbed oxygen which were attached to a film forming chamber inner wall, a metal mask and an anti-attachment shield at the same time. Further, it is preferable that the film forming chamber is heated before the substrate is carried in. After the substrate, which was heated in the pretreatment, was cooled slowly, and carried in the film forming chamber, it is heated again, which takes long time and invites lowering of throughput. Preferably, the substrate, which was heated by heat treatment which was carried out in the pretreatment, is carried in and set in the heated film forming chamber as it is, without being cooled. In passing, since heating means for heating the substrate is disposed in the substrate holder 12 in the apparatus shown in FIG. 1, it is possible to also carry out heat treatment in vacuum, which is the pretreatment, in the film forming chamber. Here, heat treatment in vacuum (anneal) is carried out in the film forming chamber before deposition is carried out. By this anneal (deairing), removed are an impurity such as oxygen and moisture attached to the substrate, and an impurity such as oxygen and moisture in a film formed on the substrate. Since the impurity, which was removed in this manner, is removed from the film forming chamber, it is preferable to carry out vacuum pumping, and further, a degree of vacuum may be heightened. Then, deposition is carried out in the film forming chamber which was vacuated up to a degree of vacuum of 5�10−3 Torr(0.665 Pa) or less, preferably 10−4-10 −6 Torr, over introducing material gas with several sccm. On the occasion of deposition, a first organic compound has been evaporated by resistance heating in advance, and flies in a direction of the substrate 10 by the shutter 14 being opened at the time of deposition. The evaporated organic compound flies upward, and mixed with material gas, and deposited on the substrate 10, passing through an opening part (not shown in the figure) which was disposed in a metal mask. In passing, on the occasion of deposition, temperature of the substrate is set to 50-200� C., preferably 65-150� C., by means for heating the substrate. In the apparatus shown in FIG. 1, heating means for heating the substrate is disposed, and heat treatment in vacuum is carried out during a period of film forming. Since there is such fear that an impurity such as oxygen and moisture is mixed in an evaporation material at the time of deposition, it is useful to carry out heat treatment in vacuum during a period of deposition and to have gas included in a film discharged. In this manner, by carrying out deposition over heating the substrate in vacuum, and by carrying out film formation up to a desired film thickness, it is possible to form a high-density organic compound layer. In passing, an organic compound, which is mentioned here, is an organic compound which has a property such as a hole injection property for accepting a hole from an anode, a hole transport property in which hole mobility is larger than electron mobility, an electron transport property in which electron mobility is larger than hole mobility, an electron injection property for accepting an electron from a cathode, a blocking property in which it is possible to block a move of a hole or an electron, and a light emission property for presenting light emission. In this manner, deposition of an organic compound is finished, and a film, which is composed of the organic compound, is formed on an anode. Further, in order to reduce an impurity such as moisture and oxygen in the obtained organic compound layer, heat treatment is carried out with a pressure of 1�10−4 Torr or less, and heat treatment for having moisture etc. mixed in at the time of deposition, discharged may be carried out. Since there is such fear that an impurity such as oxygen and moisture is mixed in an evaporation material at the time of deposition, it is useful to carry out heat treatment in vacuum after deposition, and to have gas included in a film, discharged. In case of carrying out anneal after deposition, it is preferable to carry the substrate in a processing chamber which is different from the film forming chamber, without contact with atmospheric air, and to carry out anneal in vacuum. Since heating means for heating the substrate is disposed in the apparatus shown in FIG. 1, it is possible to also carry out heat treatment in vacuum in the film forming chamber after film formation. It is preferable to carry out anneal of 100-200� C., after deposition, with further higher vacuum than a degree of vacuum on the occasion of deposition. By this anneal (deairing) after film formation, an impurity such as oxygen and moisture in an organic compound layer formed on the substrate is further removed, and a high-density organic compound layer is formed. In the organic compound layer, material gas or a main component of material gas, for example, in case that monosilane gas was introduced on the occasion of deposition, silicon of 0.01 atoms %-5 atoms % by SIMS measurement, preferably an extent of 1 atoms %-2 atoms % is designed to be included. Since a film, which includes an organic compound formed as a film by use of the film forming apparatus shown in FIG. 1, becomes a film which includes material gas or a main component of material gas, and in which it is hard to get in oxygen and moisture, improved is reliability of a light emitting device which used this film including an organic compound. The processes, which were indicated up to here, are of a case of forming a single layer of an organic compound. Hereinafter, by repeating the above-described forming processes of a single layer, a desired organic compound layer is laminated, and finally, a cathode is formed as a laminated layer. In passing, in case of laminating different evaporation materials (an organic compound and a material of a cathode), they may be carried out in separate film forming chambers, and all are laminated as a film in the same film forming chamber. As a material of a cathode, a material including magnesium (Mg), lithium (Li) or calcium (Ca), in which a work function is small, is used. Preferably, an electrode, which comprises MgAg (a material in which Mg and Ag were mixed with Mg:Ag=10:1) may be used. Besides, cited are ytterbium (Yb), MgAgAl electrodes, LiAl electrodes, or LiFAl electrodes. In this manner, it is possible to fabricate a light emitting device which has an anode, an organic compound layer which is in contact with the anode, and a cathode which is in contact with the organic compound layer. In addition, it is possible to carry out anneal before film formation, in a film forming chamber, and in that case, throughput is improved. In addition, it is possible to carry out anneal after film formation, and in that case, throughput is improved. EMBODIMENT MODE 2 Here, a film forming apparatus, which is different from the embodiment mode 1, is shown in FIG. 2. FIG. 2 shows an example of a film forming apparatus in which a deposition source is moved (or rotated), so as for a film to be formed uniformly. In FIG. 2, 20 designates a substrate, and 21 designates a chamber wall, and 22 designates a substrate holder, and 23 designates a cell, and 25a designates an evaporated first material, and 25 b designates an evaporated second material, and 26 designates a turbo molecular pump, and 27 designates a cryopump, and 28 designates a moving mechanism for moving the cell. Since there is no necessity to rotate the substrate, it is possible to provide a deposition apparatus which can correspond to a large area substrate. In addition, by the deposition cell 23 moving in a X axis direction and a Y axis direction to the substrate, it becomes possible to form a deposition film uniformly. In the deposition apparatus of this invention, on the occasion of deposition, a spacing distance d of the substrate 20 and the deposition cell 23 is narrowed to representatively 30 cm or less, preferably, 20 cm or less, more preferably 5 cm-15 cm, to dramatically improve utilization efficiency of a deposition material and throughput. In addition, there is not such a necessity that an organic compound, which is provided on the deposition cell 23, is one or of one type, and a plural number is fine. For example, other than a material of one type, which is provided in the deposition source holder as a luminescent organic compound, another organic material (dopant material), which can become dopant, may be provided all together. As an organic compound layer to be evaporated, it is configured by a host material, and a luminescent material (dopant material) whose excitation energy is lower than the host material, and it is designed in such a manner that excitation energy of dopant becomes lower than excitation energy of a hole transport property region, and excitation energy of an electron transport layer, which is preferable. By this, it is possible to prevent diffusion of molecular exciters of the dopant, and to have the dopant emit light effectively. In addition, if the dopant is a carrier-trap type material, it is possible to also heighten recombination efficiency of a carrier. In addition, such a case that a material, which can convert triplet excitation energy into light emission, was added to a mixed region as dopant is assumed to be included in this invention. In addition, in forming the mixed region, concentration gradient may be applied to the mixed region. Further, in case of using a plurality of organic compounds which are provided in one deposition source holder, it is desirable to tilt an evaporating direction so as to be crossed at a position of a material to be deposited, so that the organic compounds are mixed with each other. In addition, for the purpose of carrying out co-deposition, in the deposition cell, 4 kinds of deposition materials (e.g., as a deposition material a, 2 kinds of host materials, and as a deposition material b, 2 kinds of dopant materials) may be provided. In addition, in case of citing a major process in which there is such fear that an impurity such as oxygen and water is mixed in, to an EL material and a metal material to be evaporated, a process for setting an EL material in a film forming chamber prior to deposition, a deposition process, and so on are conceivable. In this connection, it is preferable to provide a glove in a pretreatment chamber which was coupled to a film forming chamber, and to move a deposition source in its entirety from the film forming chamber to the pretreatment chamber, and to set a deposition material in the deposition source in the pretreatment chamber. That is, designed is a manufacturing apparatus in which a deposition source is moved up to a pretreatment chamber. By doing this, it is possible to set a deposition source, while maintaining a cleaning level of the film forming chamber. Also in the film forming apparatus shown in FIG. 2, by intentionally introducing material gas at the time of film formation, and by including a component of the material gas in an organic compound film, it is possible to make a high-density film. By including a component of the material gas in the organic compound film, it is possible to block an impurity such as oxygen and moisture which causes deterioration from being intruded, diffused in a film, and to improve reliability of a light emitting device. In addition, it is possible to freely combine this embodiment mode with the embodiment mode 1. EMBODIMENT MODE 3 Here, a film forming apparatus, which is different from the embodiment mode 1, is shown in FIG. 3. In passing, the same reference numerals are used for the same places as in FIG. 1. The film forming apparatus shown in FIG. 3 is an example in which deposition is carried out over introducing material gas, which was radicalized by plasma generating means in advance, into a film forming chamber. As shown in FIG. 3, a microwave source 30 a is connected to a waveguide 30 b. This waveguide 30 b forms plasma 30 c due to glow discharge, by carrying out irradiation to material gas in a discharge tube. From the microwave source which is used here, μ wave of approximately 2.45 GHz is radiated. For example, in case that monosilane gas was used as material gas, an oxide silicon precursor such as SiHx, SiHxOy, SiOy is generated, and introduced into a film forming chamber. These radicals are easily reacted with oxygen and moisture, and it is possible to reduce oxygen concentration and a moisture amount in the film forming chamber, and accordingly, it is possible to obtain an organic compound film with high reliability. In addition, since these radicals are easily moved to, or deposited at a place with higher temperature, it is desirable to carry out deposition over heating a substrate by a heater 31 which is disposed in the substrate holder 12. In addition, for the purpose of preventing it from being moved to, or deposited on the deposition cell 13, it is desirable to cover the deposition cell 13 by a heat insulating material. In addition, it is possible to freely combine this embodiment mode with the embodiment mode 1 or the embodiment mode 2. EMBODIMENT MODE 4 Here, a film forming apparatus, which is different from the embodiment mode 1, is shown in FIG. 4. The film forming apparatus shown in FIG. 4 is an example in which, by using an ion plating method, material gas is ionized in a film forming chamber, and attached to an evaporated organic material 65, and along with it, deposition is carried out. In FIG. 4, 60 designates a substrate, and 61 designates a chamber wall, and 62 designates a substrate holder, and 63 designates a cell, and 65 designates an evaporated organic material, and 66 designates a turbo molecular pump, and 67 designates a cryopump, and 68 designates a level block, and 69 designates an anti-attachment plate. In the film forming apparatus shown in FIG. 4, disposed are an electron gun 50 for irradiating an electron beam to a crucible 52 which accommodated a material 51, and plasma generating means 64 for generating plasma 53. An electron beam is irradiated to the crucible 52 by the electron gun 50, to melt, and evaporate the material 51 in the crucible, and an evaporation flow of the material 51 is formed, and ionized by the plasma generating means 64, and the ionized evaporation flow and the organic material 65 evaporated from the deposition cell 63 are mixed, and by bombarding these against the substrate, a film is formed. In the film forming apparatus shown in FIG. 4, the material 51, which was evaporated in midstream of deposition of an organic material, is chemically attached, and, a component of the material 51 is included in an organic compound film, and thereby, it is possible to make a high-density film. By having a component of a material 51 included in an organic compound film, it is possible to block an impurity such as oxygen and moisture which causes deterioration from being intruded, diffused in a film, and to improve reliability of a light emitting device. In addition, it is possible to freely combine this embodiment mode with any one of the embodiment modes 1 through 3. As to this invention comprising the above-described configuration, it will be described in detail with embodiments shown as follows. EMBODIMENTS EMBODIMENT 1 In this embodiment, shown is an example of fabricating various light emitting devices which have yet functions of a plurality of materials, in the same manner as a function separation of a laminated configuration, at the same time of heightening mobility of carriers by mitigating an energy barrier which exists in an organic compound film. With regard to mitigation of the energy barrier in the laminated configuration, it is notably seen in a technology of insertion of a carrier injection layer. In short, in a boundary face of a laminated configuration with a large energy barrier, by inserting a material for mitigating that energy barrier, it is possible to design the energy barrier stepwise. By this, it is possible to heighten a carrier injection property from an electrode, and indeed, to lower a drive voltage to some extent. However, a problem is that, by increasing the number of layers, the number of organic boundary faces is increased conversely. This is considered to be a cause of such a fact that a single layer configuration is holding top data of drive voltage/power efficiency. Conversely speaking, by overcoming this point, over exploiting a merit of the laminated configuration (it is possible to combine various materials, and there is no necessity of a complex molecular design), it is possible to yet catch up the drive voltage/power efficiency of the single layer configuration. In this connection, in case that an organic compound film, which is composed of a plurality of functional regions, is formed between an anode and a cathode of a light emitting device, it is possible to form a configuration having a mixed region which is composed of both of a material which configures a first functional region, and a material which configures a second functional region, between the first functional region and the second functional region, but not a conventional laminated configuration in which a distinct boundary face exists. By applying the above configuration, it is conceivable that an energy barrier, which exists between functional regions, is reduced as compared to a conventional configuration, and an injection property of carriers is improved. That is, the energy barrier between functional regions is mitigated by forming the mixed region. Therefore, it becomes possible to prevent reduction of a drive voltage, and luminance lowering. From the foregoing, in this embodiment, in a light emitting device which has at least a region (first functional region) in which a first organic compound can express a function, and a region (second functional region) in which a second organic compound, which is different from a substance configuring the first functional region, can express a function, and in fabrication of a light emitting apparatus which has this, by using the film forming apparatus shown in FIG. 1, between the first functional region and the second functional region, fabricated is a mixed region which is composed of an organic compound which configures the first functional region, and an organic compound which configures the second functional region. In the film forming apparatus shown in FIG. 1, it is designed that an organic compound film, which has a plurality of functional regions, is formed in one film forming chamber, and a plurality of deposition sources are also disposed in accordance with it. In passing, a substrate, on which an anode is formed, is carried in and set. Firstly, a first organic compound, which is provided in a first material chamber, is deposited. In passing, the first organic compound has been evaporated in advance by resistance heating, and flies in a direction of a substrate by a first shutter being opened at the time of deposition. On the occasion of deposition, material gas, here, monosilane gas is introduced, and included in a film. By this, it is possible to form a first functional region 210 shown in FIG. 5(A). And, over depositing the first organic compound 17a, a second shutter is opened, and a second organic compound, which is provided in a second material chamber, is deposited. In passing, the second organic compound has also been evaporated in advance by resistance heating, and flies in a direction of the substrate by the second shutter being opened at the time of deposition. On the occasion of deposition, material gas, here, monosilane gas is introduced, and included in a film. By this, it is possible to form a first mixed region 211, which is composed of the first organic compound and the second organic compound. And, after a brief interval, only the first shutter is closed, and the second organic compound is deposited. On the occasion of deposition, material gas, here, monosilane gas is introduced, and included in a film. By this, it is possible to form a second functional region 212. In passing, in this embodiment, shown was a method of forming a mixed region by depositing 2 kinds of organic compounds at the same time, but it is also possible to form a mixed region between a first functional region and a second functional region, after a first organic compound was deposited, by depositing a second organic compound under its deposition atmosphere. Next, over depositing the second organic compound, a third shutter is opened, and a third organic compound, which is provided in a third material chamber, is deposited. In passing, the third organic compound has also been evaporated in advance by resistance heating, and flies in a direction of the substrate by the third shutter being opened at the time of deposition. On the occasion of deposition, material gas, here, monosilane gas is introduced, and included in a film. By this, it is possible to form a second mixed region 213, which is composed of the second organic compound and the third organic compound. And, after a brief interval, only the second shutter is closed, and the third organic compound is deposited. On the occasion of deposition, material gas, here, monosilane gas is introduced, and included in a film. And, by closing the third shutter, deposition of the third organic compound is completed. By this, it is possible to form a third functional region 214. Finally, by forming a cathode, a light emitting device, which is formed by the film forming apparatus of this invention, is completed. Further, as another organic compound film, as shown in FIG. 5(B), after a first functional region 220 was formed by using a first organic compound, a first mixed region 221, which is composed of the first organic compound and a second organic compound, is formed, and further, by using the second organic compound, a second functional region 222 is formed. And, in midstream of forming the second functional region 222, a third shutter is opened temporarily, and deposition of a third organic compound 17 c is carried out simultaneously, and thereby, a second mixed region 223 is formed. After a brief interval, by closing the third shutter, the second functional region 222 is formed again. And, by forming a cathode, a light emitting device is formed. Since the film forming apparatus of FIG. 2, which can form an organic compound film as described above, can form an organic compound film having a plurality of functional regions, in the same film forming chamber, it is possible to form a mixed region on a functional region boundary face. By the foregoing, it is possible to fabricate a light emitting device which does not show a clear laminated configuration (i.e., there is no distinct organic boundary face), and had a plurality of functions. In addition, the film forming apparatus of FIG. I is capable of introducing material gas (monosilane gas) intentionally at the time of the film formation, and having a component of the material gas included in an organic compound film, and by having a material with a small atomic radius (representatively, silicon) included in an organic compound film, it is possible to fit more between molecules in the mixed region. Therefore, further, it becomes possible to prevent reduction of a drive voltage, and luminance lowering. In addition, it is further possible to remove an impurity such as oxygen and moisture in a film forming chamber by the material gas, and it is possible to form a high-density organic compound layer. In addition, it is possible to freely combine this embodiment with the embodiment mode 1, the embodiment mode 2, the embodiment mode 3, or the embodiment mode 4. EMBODIMENT 2 In this embodiment, an example of a multi-chamber type manufacturing apparatus, in which fabrication from a first electrode up to sealing was fully automated, is shown in FIG. 6. FIG. 6 shows a multi-chamber manufacturing apparatus which has gates 500 a-500 y, transfer chambers 502, 504 a, 508, 514, 518, hand-over chambers 505, 507, 511, a loading chamber 501, a first film forming chamber 506H, a second film forming chamber 506B, a third film forming chamber 506G, a fourth film forming chamber 506R, a fifth film forming chamber 506E, and other film forming chambers 509, 510, 512, 513, 531, 532, installation chambers 526R, 526G, 526B, 526E, 526H in which deposition sources are installed, pretreatment chambers 503 a, 503 b, a sealing chamber 516, a mask stock chamber 524, a seal substrate stock chamber 530, cassette chambers 520 a, 520 b, a tray mounting stage 521, and a pull-out chamber 519. In passing, in the transport chamber 504 a, disposed is a transport mechanism 504 b for transporting a substrate 504 c, and in other transport chambers, transport mechanism are also provided, respectively, in the same manner. Hereinafter, a procedure for carrying a substrate, on which an anode (first electrode), and an insulator (partition wall) which covers an end part of the anode were disposed, in a manufacturing apparatus shown in FIG. 6, and for fabricating a light emitting apparatus will be shown. In passing, in case of fabricating an active matrix type light emitting apparatus, a plurality of thin film transistors (current control TFTs) which are connected to an anode, and other thin film transistors (switching TFTs, etc.) have been disposed on a substrate in advance, and a drive circuit, which is composed of thin film transistors, is also disposed. In addition, also in case of fabricating a simple matrix type light emitting apparatus, it is possible to fabricate by the manufacturing apparatus shown in FIG. 6. Firstly, the above-described substrate is set to the cassette chamber 520 a or the cassette chamber 520 b. In case that the substrate is a large size substrate (e.g., 300 mm�360 mm), it is set to the cassette chamber 520 b, and in case that it is a normal substrate (e.g., 127 mm�127 mm), after it was set to the cassette chamber 520 a, it is transferred to the tray mounting stage 521, and a plurality of substrates are set to a tray (e.g., 300 mm�360 mm). The substrate (a substrate on which an anode and an insulator which covers an end part of the anode were disposed) which was set to the cassette chamber is transferred to the transfer chamber 518. In addition, before it was set to the cassette chamber, for the purpose of reducing point defects, it is preferable to clean a surface of a first electrode (anode) by a porous sponge (representatively, made by PVA (polyvinyl alcohol), made by nylon, etc.) in which a surface-active agent (alkalescent) was contained, and to remove dusts on the surface. As a cleaning mechanism, a cleaning apparatus having a roll brush (made by PVA) which is turned around an axial line in parallel with a surface of the substrate and is in contact with the surface of the substrate may be used, and a cleaning apparatus having a disk brush (made by PVA) which is in contact with a surface of the substrate over turning around an axis line which is perpendicular to the surface of the substrate may be used. In addition, prior to forming a film, which includes an organic compound, in order to remove moisture and another gas which are included in the above-described substrate, it is preferable to carry out anneal for deairing in vacuum, and it is transferred to the pretreatment chamber 523 which was coupled to the transfer chamber 518, and anneal may be carried out there. Then, it is transferred from the transfer chamber 518 in which a substrate transfer mechanism was disposed, to a loading chamber 501. In the manufacturing apparatus of this embodiment, in the loading chamber 501, a substrate inverting mechanism is provided, and it is possible to invert the substrate properly. The loading chamber 501 is coupled to a vacuum pumping processing chamber, and it is preferable that, after vacuum pumping was carried out, inert gas is introduced to realize an atmospheric pressure. Then, it is transferred to the transfer chamber 502 which was coupled to the loading chamber 501. In order that moisture and oxygen do not exist in the transfer chamber 502 to the utmost, it is preferable that it has been vacuated in advance, and vacuum has been maintained. In addition, as the above-described vacuum pumping processing chamber, a magnetic levitation type turbo molecular pump, a cryopump, or a dry pump is provided. By this, it is possible to set ultimate vacuum of the transfer chamber which was coupled to the loading chamber to 10−5-10−6 Torr, and further, it is possible to control back diffusion of an impurity from a pump side and an air exhaust system. In order to prevent an impurity from being introduced into an apparatus inside, as gas to be introduced, inert gas such as nitrogen and rare gas is used. As these gasses which are introduced into an apparatus inside, used is one which was highly purified by a gas purification machine, before it is introduced into an apparatus. Therefore, there is a necessity of having a gas purification machine so that gas is introduced into a deposition apparatus after it was highly purified. By this, since it is possible to remove an impurity such as oxygen, water and others, which is included in gas, in advance, it is possible to prevent these impurities from being introduced into an apparatus. In addition, in case that it is desired to remove a film including an organic compound, which was formed at an unnecessary place, it is transferred to the pretreatment chamber 503 a, and a lamination layer of organic compound films may be selectively removed. The pretreatment chamber 503 a has plasma generating means, and generates plasma by exciting one kind or a plurality kinds of gasses, which were selected from Ar, H, F, and O, and thereby, carries out dry etching. In addition, a UV irradiating mechanism may be disposed in the pretreatment chamber 503 a so that ultraviolet ray irradiation can be carried out as an anode surface treatment. In addition, in order to eliminate shrink, it is desirable to carry out vacuum heating right before deposition of a film which includes an organic compound, and it is transferred to the pretreatment chamber 503 b, and in order to completely remove moisture and other gas which are included in the above-described substrate, anneal for deairing is carried out in vacuum (5�10−3 Torr (0.665 Pa) or less, preferably, 10−4-10−6 Torr). In the pretreatment chamber 503 b, by using a flat plate heater (representatively, sheath heater), a plurality of substrates are heated uniformly. In particular, in case that an organic resin film was used as a material of an interlayer insulating film and a partition wall, since there is such fear that, according to an organic resin material, it absorbs moisture easily, and further, degasification is generated, it is useful to carry out vacuum heating for removing absorbed moisture by carrying out natural cooling for 30 minutes, after heating of, for example, 30 minutes or more was carried out with 100� C.-250� C., preferably, 150� C.-200� C. before a layer including an organic compound is formed. Then, after the above-described vacuum heating was carried out, the substrate is transferred from the transfer chamber 502 to the hand-over chamber 505, and further, the substrate is transferred from the hand-over chamber 505 to the transfer chamber 504 a, without contact with atmospheric air. After that, the substrate is properly transferred to the film forming chambers 506R, 506G, 506B, 506E, which were coupled to the transfer chamber 504 a, and formed properly is an organic compound layer which comprises low molecules which become a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, or an electron injection layer. In addition, it is also possible to transfer the substrate from the transfer chamber 502 to the film forming chamber 506H, and to carry out deposition. In addition, in the film forming chamber 512, a hole injection layer, which comprises a polymeric material, may be formed by an ink-jet method and a spin coating method. In addition, the substrate is placed vertically, and a film may be formed by an ink-jet method in vacuum. Over a first electrode (anode), poly(ethylene dioxythiophene)/poly(styrene sulfonic acid) aqueous solution (PEDOT/PSS), polyaniline/camphoric sulfonic acid aqueous solution (PANI/CSA), PTPDES, Et-PTPDEK, or PPBA and so on, which act as a hole injection layer (anode buffer layer), may be applied to an entire surface and baked. On the occasion of baking, it is preferable to be carried out in a bake chamber 523. In case that a hole injection layer, which is composed of a polymeric material, was formed by an application method which used a spin coat and so on, a flatness property is improved, and it is possible to make coverage and film thickness uniformity of a film to be formed on it, better. In particular, since a film thickness of a light emitting layer becomes uniform, it is possible to obtain uniform light emission. In this case, it is desirable that, after the hole injection layer was formed by the application method, right before film formation by a deposition method, vacuum heating (100-200� C.) is carried out. On the occasion of carrying out vacuum heating, it may be carried out in the pretreatment chamber 503 b. For example, a surface of a first electrode (anode) was cleaned by a sponge, it is transferred to the cassette chamber, and transferred to the film forming chamber 512, and poly(ethylene dioxythiophene)/poly(styrene sulfonic acid) aqueous solution (PEDOT/PSS) was applied to an entire surface with a film thickness 60 nm, and thereafter, it is transferred to the bake chamber 523, and tentatively baked at 80� C., for 10 minutes, and really baked at 200� C., for 1 hour, and further, it was transferred to the pretreatment chamber 503 b, and vacuum heating (170� C., heating 30 minutes, cooling 30 minutes) was carried out right before deposition, and thereafter, it is transferred to the film forming chambers 506R, 506G, 506B, and without contact with atmospheric air, formation of a light emitting layer may be carried out by a deposition method. In particular, in case that an ITO film is used as an anode material, and concavity and convexity, and minute particles exist on a surface, by setting a film thickness of PEDOT/PSS to a film thickness of 30 nm or more, it is possible to reduce influence of these. In addition, since a wet property is not so good when PEDOT/PSS was applied over the ITO film, it is desirable to improve the wet property by carrying out cleaning by purified water once, after first time application of the PEDOT/PSS aqueous solution was carried out by a spin coating method, and to carry out second time application of the PEDOT/PSS aqueous solution by a spin coating method, and to carry out baking so as to form a film with good uniformity. In passing, by carrying out cleaning by purified water once, after the first time application was carried out, obtained is such an advantage that a surface is modified, and minute particles etc. can be also removed. In addition, in case that PEDOT/PSS was formed as a film by a spin coating method, since the film is formed over an entire surface, it is preferable to selectively remove an end surface and a peripheral part of a substrate, a terminal part, a connection region of a cathode and a lower part wiring, and so on, and it is preferable to remove by O2 ashing in the pretreatment chamber 503 a. Here, the film forming chambers 506R, 506G, 506B, 506E, 506H will be described. In each film forming chamber 506R, 506G, 506B, 506E, 506H, a movable deposition source holder (deposition cell) is installed. That is, it corresponds to the film forming chamber of the above-described embodiment mode 2, which was shown in FIG. 2. As shown in the above-described embodiment mode 2, deposition is carried out over introducing material gas on the occasion of deposition. As the material gas, concretely speaking, one kind or a plurality of kinds, which were selected from silane series gas (monosilane, disilane, trisilane etc.), SiF4, GeH4, GeF4, SnH4, or hydro carbon series gas (CH4, C2H2, C2H4, C6H6 etc.), may be used. By intentionally introducing material gas at the time of film formation, and by having a component of the material gas included in an organic compound film, it is possible to make a high-density film. By having a component of a material gas included in an organic compound film, it is possible to block an impurity such as oxygen and moisture which causes deterioration from being intruded, diffused in a film, and to improve reliability of a light emitting device. In passing, as to this deposition source holder, a plurality of them are prepared, and a plurality of containers (crucibles) in which EL materials were sealed are properly provided, and they are disposed in the film forming chamber in this state. By setting a substrate by a face-down system, and by carrying out positional alignment of a deposition mask by CCD etc., and by carrying out deposition by a resistance heating method, it is possible to carry out film formation selectively. In passing, a deposition mask is stocked in the mask stock chamber 524, and transferred to the film forming chamber on the occasion of carrying out deposition. In addition, the film forming chamber 532 is an auxiliary deposition chamber for forming a layer including an organic compound and a metal material layer. For installation of EL materials in these film forming chambers, it is preferable to use a manufacturing system which is hereinafter shown. That is, it is preferable to carry out film formation by using a container (representatively, crucible) in which an EL material has been accommodated in advance by a material maker. Further, on the occasion of installation, it is preferable to carry out without contact with atmospheric air, and on the occasion that it is transferred from a material maker, it is preferable to be introduced into the film forming chamber, in a state that the crucible is sealed hermetically in a second container. Preferably, the installation chambers 526R, 526G, 526B, 526H, 526E having vacuum pumping means coupled to each film forming chamber 506R, 506G, 506B, 506H, 506E are made to form vacuum or, inert gas atmosphere, and in this, the crucible is pulled out from the second container, and the crucible is installed in the film forming chamber. In passing, one example of the installation chamber is shown in FIG. 7, or FIG. 8. Here, a figuration of a container for transferring will be concretely described by use of FIG. 7(A). The second container which is used for transfer and divided into a upper part (721 a) and a lower part (721 b) has fixing means 706 for fixing the first container which was disposed on the upper part of the second container, a spring 705 for pressurizing the fixing means, a gas feed port 708 which was disposed on the lower part of the second container and which becomes a gas path for reducing and maintaining pressure of the second container, an O ring for fixing a upper part container 721 a and a lower part container 721 b, and a fastener 702. In this second container, installed is the first container 701 in which a purified deposition material was sealed. In passing, the second container may be formed by a material including stainless, and the first container 701 may be formed by material having titanium. In a material maker, the purified deposition material is sealed in the first container 701. And, through the O ring, the second upper part 721 a and lower part 721 b are matched, and the upper part container 721 a and the lower part container 721 b are fixed by the fastener 702, and the first container 701 is sealed hermetically in the second container. After that, through the gas feed port 708, pressure in the second container is reduced, and further, it is replaced by nitrogen atmosphere, and the spring 705 is adjusted, and the first container 705 is fixed by the fixing means 706. In this manner, when an inside of the second container is held as vacuum, and reduced pressure, nitrogen atmosphere, it is possible to prevent even attachment of slight oxygen and water to the deposition material. In this state, it is transferred to a light emitting apparatus maker, and the first container 701 is installed in a deposition chamber. After that, by heating, a deposition material is sublimated, and film formation of a deposition film is carried out. In addition, it is preferable that other components, e.g., a film thickness monitor (crystal oscillator etc.), a shutter, and so on are transferred in the same manner without contact with atmospheric air, and installed in a deposition apparatus. In addition, an installation chamber for pulling out the crucible (filled with a deposition material) which was vacuum-sealed in the container without contact with atmospheric air, and for setting the crucible to a deposition holder is coupled to a film forming chamber, and the crucible is transferred from the installation chamber by a transfer robot without contact with atmospheric air. It is preferable that vacuum pumping means is also disposed in the installation chamber, and further, means for heating the crucible is also disposed. By use of FIG. 7(A) and FIG. 7(B), a mechanism of installing the container 701, which is sealed hermetically in the second container 721 a, 721 b and transferred, in the film forming chamber will be described. FIG. 7(A) describes a cross-section surface of the installation chamber 705 which has a rotation table 707 over which the second container 721 a, 721 b, in which the first container was accommodated, is mounted, a transfer mechanism for transferring the first container, and a lift mechanism 711. In addition, the installation chamber is allocated so as to be adjacent to the film forming chamber, and it is possible to control atmosphere of the installation chamber by means for controlling atmosphere through the gas feed port. In passing, the transfer mechanism is not limited to such a configuration that the first container is sandwiched (pinched) from a upper side of the first container 701 as described in FIG. 7(B), and may be of such a configuration that the first container is transferred by sandwiching side surfaces thereof. In the above installation chamber, in such a state that the fastener 702 was released, the second container is allocated over a rotational installation table 713. Since an inside is in a vacuum state, even if the fastener 702 was released, it does not move. Then, by the means for controlling atmosphere, an inside of the installation is made to be in a reduced pressure state. When a pressure in the installation chamber and a pressure in the second container become equal, it becomes such a state that a seal of the second container can be easily broken. And, by the lift mechanism 711, the upper part 721 a of the second container is dismounted, and the rotational installation table 713 is rotated around a rotation axis 712 as an axis, and thereby, the lower part of the second container, and the first container are moved. And, the first container 701 is transferred to the deposition chamber by the transfer mechanism, and the first container 701 is installed on a deposition source holder (not shown in the figure). After that, by heating means which was disposed in the deposition source holder, a deposition material is sublimated, and film formation is initiated. At the time of this film formation, when a shutter (not shown in the figure), which was disposed in the deposition source holder, is opened, the sublimed deposition material flies in a direction of the substrate, and is deposited over the substrate, and a light emitting layer (including a hole transport layer, a hole injection layer, an electron transport layer, an electron injection layer) is formed. And, after deposition was completed, the first container is lifted from the deposition source holder, and transferred to the installation chamber, and mounted over the lower part container (not shown in the figure) of the second container which was placed over a rotation table 804, and sealed hermetically by the upper part container 721 a. At this time, it is preferable to seal the first container, the upper part container, and the lower part container hermetically, by transferred combination. In this state, the installation chamber 805 is made to be of atmospheric pressure, and the second container is pulled out from the installation chamber, and the fastener 702 is fixed, and transferred to a material maker. In addition, an example of an installation chamber in which a plurality of first containers 911 can be installed is shown in FIG. 8. In FIG. 8(A), the installation chamber 905 has a rotation table 907 on which it is possible to mount a plurality of the first containers 911 or second containers 912, a transfer mechanism 902 b for transferring the first container, and a lift mechanism 902 a, and a film forming chamber 906 has a deposition source holder 903, and a mechanism (here, not shown in the figure) for moving a deposition holder. FIG. 8(A) shows a top view, and FIG. 8(B) shows a perspective view of an inside of the installation chamber. In addition, the installation chamber 905 is placed through a gate valve 900 so as to be adjacent to the film forming chamber 906, and it is possible to control atmosphere of the installation chamber, by means for controlling atmosphere, through a gas feed port. In passing, although it is not shown in the figure, a place in which a upper part (second container) 912, which was dismounted, is placed is disposed separately. Or, it may be designed in such a manner that a robot is provided in a pretreatment chamber (installation chamber) which was coupled to the film forming chamber, and a deposition source in its entirety is moved from the film forming chamber to the pretreatment chamber, and in the pretreatment chamber, a deposition material is set to the deposition source. That is, it may be designed as a manufacturing apparatus in which a deposition source is moved up to a pretreatment chamber. By doing this, it is possible to set the deposition source, with holding a cleaning degree of the film forming chamber. By doing this, it is possible to prevent a crucible and an EL material, which was accommodated in the crucible, from being contaminated. In passing, in the installation chambers 526R, 526G, 526B, 528H, 526E, it is possible to stock a metal mask. By properly selecting EL materials which are placed in the film forming chambers 506R, 506G, 506B, 506H, 506E, as an entire light emitting device, it is possible to form a light emitting device which indicates light emission of a single color (concretely, white color), or full color (concretely, red color, green color, blue color). For example, in case of forming a green color light emitting device, if a cathode is formed, after a hole transport layer or a hole injection layer in the film forming chamber 506H, and a light emitting layer (G) in the film forming chamber 506G, and an electron transport layer or an electron injection layer in the film forming chamber 506E were sequentially laminated, it is possible to obtain the green color light emitting device. For example, in case of forming a full color light emitting device, if a cathode is formed after, using a deposition mask for R in the film forming chamber 506R, a hole transport layer or a hole injection layer, a light emitting layer (R), an electron transport layer or an electron injection layer are sequentially laminated, and using a deposition mask for G in the film forming chamber 506G, a hole transport layer or a hole injection layer, a light emitting layer (G), an electron transport layer or an electron injection layer are sequentially laminated, and using a deposition mask for B in the film forming chamber 506B, a hole transport layer or a hole injection layer, a light emitting layer (B), an electron transport layer or an electron injection layer are sequentially laminated, it is possible to obtain the full color light emitting device. In passing, an organic compound layer for indicating light emission of white color is, in case of laminating light emission layers having different light emission colors, roughly classified into a 3 wavelength type which includes 3 primary colors of red color, green color, blue color, and a 2 wavelength type which used a relation of complementary colors of blue color/yellow color, or blue-green color/orange color. It is possible to form a white color light emitting device in one film forming chamber. For example, in case of obtaining the white color light emitting device using the 3 wavelength type, prepared is a film forming chamber in which provided were a plurality of deposition source holders on which a plurality of crucibles were mounted, and in a first deposition source holder, aromatic diamine (TPD) is sealed, and in a second deposition source holder, p-EtTAZ is sealed, and in a third deposition source holder, Alq3 is sealed, and in a fourth deposition source holder, an EL material in which NileRed, which is a red color light emitting coloring matter, was added to Alq3, and in a fifth deposition source holder, Alq3 is sealed, and in this state, they are installed in each film chamber. And, the first through fifth deposition source holders starts moving in sequence, and carry out deposition to a substrate, and lamination of layers. Concretely speaking, TPD is sublimated from the first deposition source holder by heating, and deposited on an entire surface of the substrate. After that, p-EtTAZ is sublimated from the second deposition source holder, and Alq3 is sublimated from the third deposition source holder, and Alq3:NileRed is sublimated from the fourth deposition source holder, and Alq3 is sublimated from the fifth deposition source holder, and deposited over an entire surface of the substrate. After that, if a cathode is formed, it is possible to obtain the white color light emitting device. By the above-described process, after layers including organic compounds are laminated as layers properly, the substrate is transferred from the transfer chamber 504 to the hand-over chamber 507, and further, the substrate is transferred from the hand-over chamber 507 to the transfer chamber 508, without contact with atmospheric air. Then, by the transfer mechanism which is disposed in the transfer chamber 508, the substrate is transferred to the film forming chamber 510, and a cathode is formed. This cathode is a metal film (alloy such as MgAg, MgIn, CaF2, LiF, CaN, or a film formed by a co-deposition method of an element which belongs to a 1 family or a 2 family of the periodic table and aluminum, or a laminated film of these) which is formed by a deposition method which used resistance heating. In addition, a cathode may be formed by using a sputtering method. In addition, in case of fabricating a upper surface launching type light emitting device, it is desirable that a cathode is transparent or semi-transparent, and it is desirable that a thin film (1 nm-10 nm) of the above-described metal film, or a laminated layer of a thin film (1 nm-10 nm) of the above-described metal film and a transparent conductive film is used as the cathode. In this case, by using the sputtering method, a film, which is composed of a transparent conductive film (ITO(indium oxide-tin oxide alloy), indium oxide-zinc oxide alloy (In2O3�ZnO), zinc oxide (ZnO) etc.), may be formed in the film forming chamber 509. By the above-described processes, a light emitting device of a laminated layer configuration is formed. In addition, it may be designed that it is transferred to the film forming chamber 513 which was coupled to the transfer chamber 508, and a protective film, which is composed of a silicon nitride film, or a silicon nitride oxide film, is formed for sealing. Here, in the film forming chamber 513, a target which is composed of silicon, or a target which is composed of silicon oxide, or a target which is composed of silicon nitride, is provided. For example, using the target which is composed of silicon, by changing film forming chamber atmosphere to nitrogen atmosphere or atmosphere including nitrogen and argon, it is possible to form a silicon nitride film on a cathode. In addition, it may be formed by use of a thin film in which a major component is carbon (a DLC film, a CN film, an amorphous carbon film) as a protective film, and a film forming chamber which used a CVD method may be disposed separately. A diamond like carbon film (also called as DLC film) can be formed by a plasma CVD method (representatively, a RF plasma CVD method, a microwave CVD method, an electron cyclone resonance (ECR) CVD method, a heat filament CVD method etc.) a combustion-flame method, a sputtering method, an ion beam deposition method, a laser deposition method, etc. As reactive gas which is used for film formation, used are hydrogen gas, and carbon hydride series gas (e.g., CH4, C2H2, C2H6 etc.), and it is ionized by glow discharge, and ions are accelerated and bombarded to a cathode to which a negative self bias was applied, to form a film. In addition, the CN film may be formed by using C2H4 gas and N2 gas as reactive gas. In passing, the DLC film and the CN film are insulating films which are transparent or semi-transparent to visible light. To be transparent to visible light means that a transmission factor of visible light is 80-100%, and to be semi-transparent to visible light means that a transmission factor of visible light is 50-80%. In this embodiment, on a cathode, a protective layer, which comprises a laminated layer of a first inorganic insulating film, a stress relaxing film, and a second inorganic insulating film, is formed. For example, it may be designed that, after the cathode was formed, it is transferred to the film forming chamber 513, and the first inorganic insulating film is formed, and it is transferred to the film forming chamber 532, and the stress relaxing film (a layer including an organic compound, etc.) which has a hygroscopic property and transparency is formed by a deposition method, and further, it is transferred again to the film forming chamber 513, and the second inorganic insulating film is formed. Then, the substrate on which a light emitting device was formed, is transferred from the transfer chamber 508 to the hand-over chamber 511, without contact with atmospheric air, and further, transferred from the hand-over chamber 511 to the transfer chamber 514. Then, the substrate on which a light emitting device was formed, is transferred from the transfer chamber 514 to the sealing chamber 516. A seal substrate is set from outside to the load chamber 517, and prepared. In passing, in order to remove an impurity such as moisture, it is desirable to carry out anneal in advance in vacuum. And, in case of forming a seal member for gluing the substrate on which a light emitting device was formed with the seal substrate, the seal member is formed in the sealing chamber 527, and the seal substrate, on which the seal member was formed, is transferred to the seal substrate stock chamber 530. In passing, in the sealing chamber, a drying agent may be disposed over the seal substrate. In passing, here, an example, in which the seal member was formed over the seal substrate, was shown, but in particular, it is not restrictive, and the seal member may be formed on the substrate on which a light emitting device was formed. Then, the sealing chamber 516, the substrate and the seal substrate are glued together, and UV rays are irradiated to a pair of the glued substrates by a ultraviolet ray irradiating mechanism which was disposed in the sealing chamber 516, to cure the seal member. In passing, here, as the seal member, ultraviolet ray cured resin was used, but if it is an adhesive agent, it is not particularly restrictive. Then, the pair of glued substrates are transferred from the sealing chamber 516 to the transfer chamber 514, and then, from the transfer chamber 514 to the pull-out chamber 519, and then, pulled out. As above, by using the manufacturing apparatus shown in FIG. 6, until a light emitting device is completely sealed in a hermetically enclosed space, it is not needed to be exposed to atmospheric air, and therefore, it becomes possible to fabricate a light emitting apparatus with high reliability. In passing, in the transfer chambers 514, 518, vacuum, and nitrogen atmosphere with atmospheric pressure are repeated, but, it is desired that vacuum is maintained on a steady basis in the transfer chambers 502, 504, 508. In passing, although it is not shown in the figure here, disposed is a control control apparatus for realizing automation by controlling a path through which the substrate is moved to an individual processing chamber. In addition, in the manufacturing apparatus shown in FIG. 6, the substrate, on which a transparent conductive film (or a metal film (TiN)) was disposed as an anode, is carried in, and a layer including an organic compound was formed, and thereafter, a transparent or semi-transparent cathode (e.g., a laminated layer of a thin metal film (Al, Ag) and a transparent conductive film) is formed, and thereby, it is also possible to form a upper surface launching type (or upper/lower surfaces launching type) light emitting device. In passing, the upper surface launching type light emitting device means a device which gets through a cathode and pulls out emitted light which was generated in an organic compound layer. In addition, in the manufacturing apparatus shown in FIG. 6, the substrate, on which a transparent conductive film was formed as an anode, is transferred, and after a layer including an organic compound was formed, a cathode, which comprising a metal film (Al, Ag), is formed, and thereby, it is also possible to form a lower surface launching type light emitting device. In passing, the lower surface launching type light emitting device means a device which pulls out emitted light which was generated in an organic compound layer from an anode which is a transparent electrode toward TFT, and further, which gets it through the substrate. In addition, it is possible to freely combine this embodiment with the embodiment mode 1, the embodiment mode 2, the embodiment mode 3, the embodiment mode 4 or the embodiment 1. EMBODIMENT 3 In this embodiment, an example for fabricating a light emitting apparatus (upper surface launching configuration) which had a light emitting device in which an organic compound layer is used as a light emitting layer, on a substrate which has an insulating surface is shown in FIG. 9. In passing, FIG. 9(A) is a top view showing a light emitting apparatus, and FIG. 9(B) is a cross-sectional view in which FIG. 9(A) was cut with A-A′. 1101 shown by a dotted line designates a source signal line drive circuit, and 1102 designates a pixel portion, and 1103 designates a gate signal line drive circuit. In addition, 1104 designates a transparent seal substrate, and 1105 designates a first seal member, and an inside which was surrounded by the first seal member is filled with a transparent second seal member 1107. In passing, in the first seal member 1105, included is a gap member for holding a substrate interval. In passing, 1108 designates a wiring for transferring a signal which is imputed to the source signal line drive circuit 1101 and the gate signal line drive circuit 1103, and it accepts a video signal and a clock signal from FPC (Flexible Print Circuit) 1109 which becomes an external input terminal. In passing, here, only FPC is shown in the figure, but a printed wiring board (PWB) may be attached to this FPC. Next, a cross-sectional configuration will be described by use of FIG. 9(B). A drive circuit and a pixel portion are formed over a substrate 1110, but here, the source signal line drive circuit 1101 as the drive circuit and the pixel part 1102 are shown. In passing, in the source signal line drive circuit 1101, formed is a CMOS circuit in which a n-channel type TFT 1123 and a p-channel type TFT 1124 were combined. In addition, TFT which forms the drive circuit may be formed by publicly known CMOS circuit, PMOS circuit or NMOS circuit. In addition, in this embodiment, shown was a driver integral type in which a drive circuit was formed over a substrate, but it is not necessary required, and it is possible to form outside not but over the substrate. In addition, a configuration of TFT in which a polysilicon film is used as an active layer is not particularly restrictive, and may be a top gate type TFT, and may be a bottom gate type TFT. In addition, the pixel portion 1102 is formed by a plurality of pixels which includes a switching TFT 1111, a current control TFT 1112, and a first electrode (anode) 1113 which was electrically connected to its drain. As the current control TFT 1112, either a n-channel type TFT or a p-channel type TFT may be acceptable, but in case that it is connected to an anode, it is desirable to use a p-channel type TFT. In addition, it is desirable to properly dispose holding capacity (not shown in the figure). In passing, here, among pixels which were placed in countless numbers, only a cross-sectional configuration of one pixel was shown, and an example in which 2 TFTs were used for that one pixel was shown, but TFTs of 3 pieces, or more than that, may be properly used. Here, since it is of such a configuration that the first electrode 1113 is in directly contact with a drain of TFT, it is desirable that a lower layer of the first electrode 1113 is made to be a material layer which can take an ohmic contact with a drain which comprises silicon, and a top layer which is in contact with a layer including an organic compound comprises a material with a large work function. For example, if realized is a 3 layer configuration of a titanium nitride film, a film whose main component is aluminum, and a titanium nitride film, resistance as a wiring is low, and a good ohmic contact is taken, and it is possible to function as an anode. In addition, the first electrode 1113 may be a single layer of a titanium nitride film, a chromium film, a tungsten film, a Zn film, a PT film and so on, and a laminated layer of 3 layers or more may be used. In addition, over both sides of the first electrode (anode) 1113, formed is an insulator (called as bank, partition wall, barrier, mound) 1114. The insulator 1114 may be formed by an organic resin film or an insulating film which includes silicon. Here, as the insulator 1114, using a positive type photosensitive acryl resin film, an insulator of a shape shown in FIG. 9 is formed. In order to make a coverage better, it is designed in such a manner that a curved surface having curvature is formed on a upper end part or a lower end part of the insulator 1114. For example, in case that positive type photosensitive acryl was used as a material of the insulator 1114, it is desirable to make only the upper end part of the insulator 1114 hold a curved surface having a curvature radius (0.2 μm-3 μm). In addition, as the insulator 1114, it is possible to use any one of a negative type which becomes irresolvable in etchant by photosensitive light, and a positive type which becomes resolvable in etching by light. In addition, the insulator 1114 may be covered with a protective film which comprises an aluminum nitride film, an aluminum oxide film, a thin film whose main component is carbon, or a silicon nitride film. In addition, on the first electrode (anode) 1113, a layer 1115 which includes an organic compound is selectively formed by a deposition method, over introducing monosilane gas. Further, over the film 1115 which includes an organic compound, a second electrode (cathode) 1116 is formed. As the cathode, a material with a small work function (Al, Ag, Li, Ca, or these alloys MgAg, MgIn, AlLi, CaF2, or CaN) may be used. Here, in order that emitted light is penetrated, as the second electrode (cathode) 1116, used is a laminated layer of a metal thin film whose film thickness was thinned, and a transparent conductive electrode (ITO(indium oxide-tin oxide alloy), indium oxide-zinc oxide alloy(In2O3-ZnO), zinc oxide(ZnO) etc.). In this manner, a light emitting device 1118, which comprises the first electrode (anode) 1113, the layer 1115 which includes an organic compound, and the second electrode (cathode) 1116, is formed. In this embodiment, as the layer 1115 which includes an organic compound, an aromatic diamine layer(TPD), a p-EtTAZ layer, an Alq3 layer, an Alq3 layer in which Nile red was doped, and an Alq3 layer are laminated in sequence, to obtain white color light emission. In this embodiment, since the light emitting device 1118 is an example of white color light emission, a color filter (for the purpose of simplification, an overcoat layer is not shown in the figure, here), which comprises a color layer 1131 and a light shielding layer (BM) 1132, is disposed. In addition, if layers including organic compounds by which light emissions of R, G, B are obtained is selectively formed, it is possible to obtain full-color display even if a color filter is not used. In addition, in order to seal the light emitting device 1118, a transparent protective layer 1117 is formed. As this transparent protective layer 1117, it is preferable to use an insulating film which is obtained by a sputter method (DC system or RF system) and a PCVD method and in which silicon nitride or silicon nitride oxide is a main component, a thin film in which carbon is a main component (DLC film, CN film etc.), or a laminated layer of these. If formed in atmosphere including nitrogen and argon, using a silicon target, it is possible to obtain a silicon nitride film with a high blocking effect against an impurity such as moisture and alkali metal. In addition, a silicon nitride target may be also used. In addition, the transparent protective layer may be also formed by using a film forming apparatus which used remote plasma. In addition, in order to have emitted light penetrate through the transparent protective layer, it is preferable that a film thickness of the transparent protective layer is as thin as possible. In addition, in order to seal the light emitting device 1118, under inert gas, the seal substrate 1104 is glued by the first seal member 1105 and the second seal member 1107. In passing, as the first seal member 1105, the second seal member 1107, it is preferable to use epoxy series resin. In addition, it is desired that the first seal member 1105, and the second seal member 1107 are of a material which does not pass moisture and oxygen as far as possible. In addition, in this embodiment, as a material which configures the seal substrate 1104, it is possible to use a plastic substrate which comprises FRP(Fiberglass-Reinforced Plastics), PVF(PolyVinyl Fluoride), a mylar, polyester or acryl etc. In addition, after the seal substrate 1104 was glued by using the first seal member 1105 and the second seal member 1107, it is possible to seal by a third seal member, so as to further cover a side surface (exposed surface). By doing the foregoing, by encapsulating a light emitting device in the first seal member 1105, the second seal member 1107, it is possible to completely shield the light emitting device from outside, and it is possible to prevent a substance such as moisture and oxygen, which urges deterioration of an organic compound layer from being intruded from outside. Therefore, it is possible to obtain a light emitting device with high reliability. In addition, if a transparent conductive film is used as the fist electrode 1113, it is possible to fabricate a both surface light emission type light emitting apparatus. In addition, in this embodiment, shown was an example of such a configuration (hereinafter, called as upper surface launching configuration) that a layer, which includes an organic compound, is formed over an anode, and a cathode, which is a transparent electrode, is formed over the layer which includes an organic compound, but a configuration which has a light emitting device in which a layer, which includes an organic compound, is formed over an anode, and a cathode is formed over an organic compound layer, and in which emitted light, which was generated in the layer which includes an organic compound, is pulled out from the anode, which is a transparent electrode, toward TFT (hereinafter, called as lower surface launching configuration) may be used. Here, one example of a light emitting apparatus of the lower surface launching configuration is shown in FIG. 10. In passing, FIG. 10(A) is a top view showing a light emitting apparatus, and FIG. 10(B) is a cross-sectional view in which FIG. 10(A) was cut along A-A′. 1201 shown by a dotted line designates a source signal line drive circuit, and 1202 designates a pixel portion, and 1203 designates a gate signal line drive circuit. In addition, 1204 designates a seal substrate, and 1205 designates a seal member in which included is a gap member for holding an interval of a hermetically enclosed space, and an inside which was surrounded by the seal member 1205 is filled with inert gas (representatively, nitrogen). As to an inside space which was surrounded by the seal member 1205, minute amounts of moisture is removed by a drying agent 1207, and it is sufficiently dried. In passing, 1208 designates a wiring for transferring a signal which is imputed to the source signal line drive circuit 1201 and the gate signal line drive circuit 1203, and it accepts a video signal and a clock signal from FPC (Flexible Print Circuit) 1209 which becomes an external input terminal. Next, a cross-sectional configuration will be described by use of FIG. 10(B). A drive circuit and a pixel portion are formed over a substrate 1210, but here, the source signal line drive circuit 1201 as the drive circuit and the pixel portion 1202 are shown. In passing, in the source signal line drive circuit 1201, formed is a CMOS circuit in which a n-channel type TFT 1223 and a p-channel type TFT 1224 were combined. In addition, the pixel portion 1202 is formed by a plurality of pixels which includes a switching TFT 1211, a current control TFT 1212, and a first electrode (anode) 1213 which comprises a transparent conductive film electrically connected to its drain. Here, it is of such a configuration that the first electrode 1213 is formed so as to be partially overlapped with a connection electrode, and the first electrode 1213 is electrically connected to a drain region of TFT through the connection electrode. The first electrode 1213 has transparency, and it is desired to use a conductive film with a large work function (ITO(indium oxide-tin oxide alloy), indium oxide-zinc oxide alloy(In2O3�ZnO), zinc oxide(ZnO) etc.). In addition, over both ends of the first electrode (anode) 1213, formed is an insulator (called as bank, partition wall, barrier, mound) 1214. In order to make a coverage better, it is designed in such a manner that a curved surface having curvature is formed over a upper end part or a lower end part of the insulator 1214. In addition, the insulator 1214 may be covered with a protective film which comprises an aluminum nitride film, an aluminum nitride oxide film, a thin film in which carbon is a main component, or a silicon nitride film. In addition, over the first electrode (anode) 1213, a layer 1215 which includes an organic compound is selectively formed by carrying out deposition of an organic compound material, over introducing monosilane gas. Further, over the film 1215 which includes an organic compound, a second electrode (cathode) 1216 is formed. As the cathode, a material with a small work function (Al, Ag, Li, Ca, or these alloys MgAg, MgIn, AlLi, CaF2, or CaN) may be used. In this manner, a light emitting device 1218, which comprises the first electrode (anode) 1213, the layer 1215 which includes an organic compound, and the second electrode (cathode) 1216, is formed. Here, the light emitting device 1218 is one of light emitting devices which can obtain single color light emission of R, G, or B, and fill-color is realized by 3 light emitting devices in which layers, which include organic compounds by which light emissions of R, G, B are obtained, were selectively formed. In addition, in order to seal the light emitting device 1218, a protective layer 1217 is formed. As this transparent protective layer 1217, it is preferable to use an insulating film which is obtained by a sputter method (DC system or RF system) and a PCVD method and in which silicon nitride or silicon nitride oxide is a main component, or a thin film in which carbon is a main component (DLC film, CN film etc.), or a laninated layer of these. If formed in atmosphere including nitrogen and argon, using a silicon target, it is possible to obtain a silicon nitride film with a high blocking effect against an impurity such as moisture and alkali metal. In addition, a silicon nitride target may be also used. In addition, the protective layer may be also formed by using a film forming apparatus which used remote plasma. In addition, in order to seal the light emitting device 1218, under inert gas, the seal substrate 1204 is glued by the seal member 1205. In the seal substrate 1204, a concave part, which was formed by a sandblast method, has been formed in advance, and the drying agent 1207 is glued to the concave part. In passing, as the seal member 1205, it is preferable to use epoxy series resin. In addition, it is desired that the seal member 1205 is of a material which does not pass moisture and oxygen as far as possible. In addition, in this embodiment, as a material which configures the seal substrate 1104 having the concave part, it is possible to use a plastic substrate which comprises FRP(Fiberglass-Reinforced Plastics), PVF(PolyVinyl Fluoride), a mylar, polyester or acryl etc. In addition, it is possible to seal by a metal can, to an inside of which a drying agent was glued. In addition, it is possible to freely combine this embodiment with any one of the embodiment modes 1 through 4, the embodiment 1, or the embodiment 2. EMBODIMENT 4 In this embodiment, a cross-sectional configuration of one pixel, in particular, shapes of a connection of a light emitting device and TFT, a partition wall which is located between pixels will be described. In FIG. 11(A), 40 designates a substrate, and 41 designates a partition wall (also called as bank), and 42 designates an insulating film, and 43 designates a first electrode (anode), and 44 designates a layer which includes an organic compound, and 45 designates a second electrode (cathode), and 46 designates TFT. In TFT 46, 46 a designates a channel forming region, and 46 b, 46 c designate a source region or a drain region, and 46 designates a gate electrode, and 46 e, 46 f designate a source electrode or a drain electrode. Here, a top-gate type TFT is shown, but it is not restrictive, and an inversely staggered type TFT may also be used, and a forwardly staggered type TFT may also be used. In passing, 46 f designates an electrode for connecting with TFT 46 by being overlapped with the first electrode 43 partially in contact with it. In addition, a cross-sectional configuration, which is partially different from FIG. 1(A), is shown in FIG. 11(B). In FIG. 11(B), an overlapping way of the first electrode and the electrode is different from the configuration of FIG. 11(A), and after the first electrode was patterned, the electrode is formed so as to be partially overlapped, and thereby, it is connected to TFT. In addition, a cross-sectional configuration, which is partially different from FIG. 1(A), is shown in FIG. 11(C). In FIG. 11(C), 1 layer of an interlayer insulating film is further disposed, and the first electrode is connected to the electrode of TFT through a contact hole. In addition, as a cross-sectional shape of the partition wall 41, as shown in FIG. 11(D), it may be made also as a taper shape. It is obtained by etching non-photosensitive organic resin or an inorganic film, after a resist was exposed to light by using a photolithography method. In addition, if positive type photosensitive organic resin is used, it is possible to make a shape as shown in FIG. 11(E), a shape having a curved surface over a upper end part. In addition, if negative type photosensitive organic resin is used, it is possible to make a shape as shown in FIG. 11(F), a shape having curved surfaces over a upper end part and a lower end part. In addition, it is possible to freely combine this embodiment with the embodiment mode 1, the embodiment mode 2, the embodiment mode 3, the embodiment mode 4, the embodiment 1, the embodiment 2, or the embodiment 3. EMBODIMENT 5 In this embodiment, an example of fabricating a passive matrix type light emitting apparatus (also called as a simple matrix type light emitting apparatus) will be shown. Firstly, over a glass substrate, a plurality of first wirings are formed in a stripe shape by a material such as ITO (material which becomes an anode). Then, a partition wall, which comprises a resist or photosensitive resin, is formed so as to surround a region which becomes a light emitting region. Then, by a deposition method, a layer which includes an organic compound is formed in a region which was surrounded by the partition wall. In case of realizing full-color display, a material is properly selected, and over introducing monosilane gas, the layer which includes an organic compound is formed by a deposition method. Then, over the partition wall and the layer which includes an organic compound, a plurality of second wirings in a stripe shape are formed by a metal material (material which becomes a cathode) such as Al or Al alloy, so as to be crossed with the plurality of first wirings which comprises ITO. By the above-described processes, it is possible to form a light emitting device in which the layer including an organic compound was used as a light emitting layer. Then, a seal substrate is glued by a seal member, or sealed by disposing a protective film over the second wiring. As the seal substrate, used is a glass substrate, a plastic substrate which comprises polypropylene, polypropylenesulfide, polycarbonate, polyetherimide, polyphenylenesulfide, polyphenyleneoxide, polysulfone, or polyphtalamide. One example of a cross-sectional view of a display apparatus of this embodiment is shown in FIG. 12(A). Disposed is a pixel portion 1321 in which a first electrode and a second electrode are crossed over a main surface of a substrate 1300, and a light emitting device was formed at its crossing part. That is, formed is the pixel part 1321 in which luminescent pixels are arranged in a matrix shape. The number of pixels is 640�480 dots in case of VGA specification, 1024�768 dots in case of XGA specification, and 1365�1024 dots in case of SXGA, or 1600�1200 dots in case of UXGA specification, and the number of the first electrodes and the second electrodes are disposed in accordance with it. Further, on a peripheral part of the pixel portion 1321, which is an end part of the substrate 1301, disposed is an input terminal part in which formed was a terminal pad which is connected to an external circuit. In the display apparatus shown in FIG. 12(A), in the pixel portion, over a main surface of the substrate 1300, formed are a first electrode 1302 which is extended in a left-right direction, a thin film 1305 (since a medium, which emits light by electroluminescence, is included, as a matter of convenience, it is called as EL layer in the following explanation) which includes an illuminant formed over its upper layer, and a second electrode 1306 which is formed over its upper layer and extended in a up-down direction, and over its crossing part, a pixel is formed. That is, by forming the fist electrode 1302 and the second electrode 1306 row-wise and column-wise, pixels are disposed in a matrix shape. An input terminal is formed by the same material as the first electrode or the second electrode. The number of this input terminal is the same number of the first electrode and the second electrode which were disposed row-wise and column-wise. A cross-sectional shape of the partition wall 1304 has a curved surface shape from a lower end part which is in contact with the first electrode 1302 to a upper end part. The curved surface shape is a shape which has at least one curvature radius, a center of which is located at the partition wall or a lower layer side thereof, or, a shape which has at least one first curvature radium, a center of which is located at a lower end part which is in contact with the first electrode 1302 and at an outside of the partition wall 1304, and at least one second curvature radium, a center of which is located at a upper end part of the partition wall 1304 and at the partition wall or a lower layer side thereof. The cross-sectional shape may be such a thing that curvature is continuously changed from the lower end part of the partition wall 1304 to the upper end part. The EL layer is formed along the curved surface shape, and stress is mitigated by the curved surface shape. That is, in a light emitting device in which different members were laminated, there is such an operation that strain due to its thermal stress is mitigated. Shown is such a mode that an opposite substrate 1350 for sealing the pixel part 1321 is firmly fixed by a seal member 1341. In a space between the substrate 1301 and the opposite substrate 1350, inert gas may be filled, and an organic resin material 1340 may be encapsulated. In any case, since a light emitting device in the pixel portion 1321 is coated with a barrier insulating film 1307, it is possible to prevent deterioration due to an extrinsic impurity, even if a drying agent is not disposed particularly. In addition, FIG. 12(A) corresponds to each pixel of the pixel part 1321, and at the opposite substrate 1350 side, formed are single color layers 1342-1344. A planarization layer 1345 prevents a step due to the single color layer. On the other hand, FIG. 12(B) is of such a structure that, at the substrate 1301 side, disposed were the single color layers 1342-1344, and over the planarization film 1345, the first electrode 1302 is formed. In addition, FIG. 12(B) is different from FIG. 12(A) in a light emitting direction. In passing, the same reference numerals are used for the same portions. In addition, this invention is not restricted to a full-color display apparatus, and can be also implemented for a single color light emitting apparatus, for example, a surface light source, an electric illumination apparatus. In addition, it is possible to freely combine this embodiment with any one of the embodiment modes 1 through 4, the embodiment 1, or the embodiment 2.

EMBODIMENT 7 In this embodiment, an example of an inline type manufacturing apparatus, in which fabrications from a first electrode up to sealing were totally automated, is shown in FIG. 14 FIG. 14 shows an inline type manufacturing apparatus which has gates 1000 a-1000 u, transfer chambers 1002, 1004 a, 1014, a hand-over chamber 1011, a first film forming chamber 1006H, a second film forming chamber 1006B, a third film forming chamber 1006G, a fourth film forming chamber 1006R, a fifth film forming chamber 1006E, an auxiliary film forming chamber 1006G″, an auxiliary film forming chamber 1006R″, an auxiliary film forming chamber 1006B″, other film forming chambers 1009, 10010, 1013, installation chambers in which deposition sources are installed 1026R, 1026G, 1026B, 1026R″, 1026G″, 1026B″, 1026E, 1026H, a pretreatment chamber 1003 a, a sealing chamber 1018, a sealing chamber 1016, a seal substrate stock chamber 1030, a substrate carry-in chamber 1020, and a pull-out chamber 1019. In passing, in the transfer chamber 1004 a, disposed is a transfer mechanism 1004 b which has a plurality of arms for transferring or inverting the substrate 1004 c, and in other transfer chambers, transfer mechanisms are disposed, respectively, in the same manner. Hereinafter, a procedure for carrying a substrate, on which an anode (first electrode) and an insulator (partition wall) for covering an end part of the anode were disposed in advance, in the manufacturing apparatus shown in FIG. 14, to fabricate a light emitting apparatus will be shown. Firstly, in the substrate carry-in chamber 1020, the above-described substrate is set. Ii is designed to be able to correspond to such a case that the substrate is a large size substrate (e.g., 600 mm�720 mm), and such a case that it is a normal substrate (e.g., 127 mm�127 mm). The substrate carry-in chamber 1020 is coupled to a vacuum pumping processing chamber, and it is desirable that, after vacuum pumping was carried out, inert gas is introduced, and atmospheric pressure is realized. The substrate (substrate on which an anode, and an insulator for covering an end part of the anode were disposed), which was set to the substrate carry-in chamber, is transferred to the transfer chamber 1002. In order that moisture and oxygen do not exist in the transfer chamber 1002 to the utmost, it is preferable that it has been vacuated in advance and vacuum has been maintained. In addition, before it is set to the cassette chamber, for the purpose of reducing point defects, it is preferable to clean a surface of a first electrode (anode) by a porous sponge (representatively, made by PVA (polyvinyl alcohol), made by nylon, etc.) in which a surface-active agent (alkalescent) was contained, and to remove dusts over the surface. In addition, before a layer which includes an organic compound is formed, in order to remove moisture and other gas which are included in the above-described substrate, it is preferable to carry out anneal for deairing in vacuum, and anneal may be carried out in the transfer chamber 1002, or the pretreatment chamber 1003 a. In addition, in the substrate transfer mechanism which was disposed in the transfer chamber 1002, a substrate inverting mechanism is provided, and it is possible to inverse the substrate properly. In addition, as for the above-described vacuum pumping processing chamber, a magnetic levitation type turbo molecular pump, a cryopump, or a dry pump is provided. In addition, in case that it is intended to remove a film which was formed at a unnecessary place and includes an organic compound, it is transferred to the pretreatment chamber 1003 a, and a laminated layer of an organic compound film may be selectively removed. The pretreatment chamber 1003 a has plasma generating means, and by exciting one kind or plural kinds of gasses, which were selected from Ar, H, F, and O to generate plasma, dry etching is carried out. In addition, in order that ultraviolet ray irradiation can be carried out as anode surface treatment, a UV irradiation mechanism may be provided in the pretreatment chamber 1003 a. In addition, in order to eliminate shrink, it is desirable to carry out vacuum heating right before deposition of a film which includes an organic compound, and in order to completely remove moisture and other gas which are included in the above-described substrate, in the transfer chamber 1002, anneal for deairing is carried out in vacuum (5�10−3 Torr (0.665 Pa) or less, preferably, 10−4-10−6 Torr). Then, after the above-described vacuum heating was carried out, it is transferred to the film forming chamber 1006H, and deposition is carried out. Then, the substrate is properly transferred from the transfer chamber 1002 to the film forming chambers 1006R, 1006G, 1006B, 1006R″, 1006G″, 1006B″, 1006E which were coupled to the transfer chamber 1004 a, and an organic compound layer, which becomes a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, or an electron injection layer and which is composed of low molecules, is properly formed. In addition, a film forming chamber for forming a hole injection layer, which is composed of a polymeric material, by an ink-jet method and a spin coating method etc. may be disposed separately. In addition, the substrate is placed vertically, and a film may be formed by an ink-jet method in vacuum. In addition, in case that PEDOT/PSS was formed as a film by a spin coat method, since a film is formed over an entire surface, it is desirable to selectively remove an end surface and a peripheral part of a substrate, a terminal part, a connection region of a cathode and a lower part wiring, and so on, and it is desirable to remove by O2 ashing etc. in the pretreatment chamber 1003 a. Here, the film forming chambers 1006R, 1006G, 1006B, 1006R″, 1006G″, 1006B″, 1006E, 1006H will be described. In each film forming chamber 1006R, 1006G, 1006B, 1006R″, 1006G″, 1006B″, 1006E, 1006H, a movable deposition source holder (deposition cell) is installed. That is, it corresponds to the film forming chamber of the above-described embodiment mode 2, which was shown in FIG. 2. As shown in the above-described embodiment mode 2, deposition is carried out over introducing material gas on the occasion of deposition. As the material gas, concretely speaking, one kind or a plurality of kinds, which were selected from silane series gas (monosilane, disilane, trisilane etc.), SiF4, GeH4, GeF4, SnH4, or hydro carbon series gas (CH4, C2H2, C2H4, C6H6 etc.), may be used. By intentionally introducing material gas at the time of film formation, and by having a component of the material gas included in an organic compound film, it is possible to make a high-density film. By having a component of a material gas included in an organic compound film, it is possible to block an impurity such as oxygen and moisture which causes deterioration from being intruded, diffused in a film, and to improve reliability of a light emitting device. In passing, as to this deposition source holder, a plurality of them are prepared, and a plurality of containers (crucibles) in which EL materials were sealed are properly provided, and they are disposed in the film forming chamber in this state. By setting a substrate by a face-down system, and by carrying out positional alignment of a deposition mask by CCD etc., and by carrying out deposition by a resistance heating method, it is possible to carry out film formation selectively. In passing, a mask stock chamber for storing a deposition mask may be disposed. For installation of EL materials in these film forming chambers, it is preferable to use the manufacturing system which was shown in FIG. 7, FIG. 8 of the above-described embodiment 1. That is, it is preferable to carry out film formation by using a container (representatively, crucible) in which an EL material has been accommodated in advance by a material maker. Further, on the occasion of installation, it is preferable to carry out without contact with atmospheric air, and on the occasion that it is transferred from a material maker, it is preferable to be introduced into the film forming chamber, in a state that the crucible is sealed hermetically in a second container. Preferably, the installation chambers 1026R, 1026G, 1026B, 1026R″, 1026G″, 1026B″, 1026H, 1026E having vacuum pumping means coupled to each film forming chamber 1006R, 1006G, 1006B, 1006R″, 1006G″, 1006B″, 1006E, 1006H are made to form vacuum or, inert gas atmosphere, and in this state, the crucible is pulled out from the second container, and the crucible is installed in the film forming chamber. By doing this, it is possible to prevent a crucible, and an EL material, which was accommodated in the crucible, from being contaminated. In passing, it is possible to stock metal masks in the installation chambers 1026R, 1026G, 1026B, 1026R″, 1026G″, 1026B″, 1026H, 1026E. By properly selecting EL materials which are placed in the film forming chambers 1006R, 1006G, 1006B, 1006R″, 1006G″, 1006B″, 1006E, 1006H, as an entire light emitting device, it is possible to form a light emitting device which indicates light emission of a single color (concretely, white color), or full color (concretely, red color, green color, blue color). For example, in case of forming a green color light emitting device, if a cathode is formed, after a hole transport layer or a hole injection layer in the film forming chamber 1006H, and a light emitting layer (G) in the film forming chamber 1006G, and an electron transport layer or an electron injection layer in the film forming chamber 1006E were sequentially laminated, it is possible to obtain the green color light emitting device. For example, in case of forming a full color light emitting device, using a deposition mask for R in the film forming chamber 1006R, a hole transport layer or a hole injection layer, a light emitting layer (R), an electron transport layer or an electron injection layer are sequentially laminated, and using a deposition mask for G in the film forming chamber 1006G, a hole transport layer or a hole injection layer, a light emitting layer (G), an electron transport layer or an electron injection layer are sequentially laminated, and using a deposition mask for B in the film forming chamber 1006B, a hole transport layer or a hole injection layer, a light emitting layer (B), an electron transport layer or an electron injection layer are sequentially laminated, it is possible to obtain the full color light emitting device. In addition, by utilizing the auxiliary film forming chambers 1006R″, 1006G″, 1006B″, without stopping a line even during such a period that cleaning is carried out in the film forming chambers 1006R, 1006G, 1006B, it is possible to fabricate a panel. In addition, it is possible to increase the number of panels by activating both sides. By the above-described process, layers which include organic compounds were laminated properly, and thereafter, by the transfer mechanism which is disposed in the transfer chamber 1004 a, the substrate is transferred to the film forming chamber 1010, and a cathode is formed. This cathode is a metal film (alloy such as MgAg, MgIn, CaF2, LiF, CaN, or a film formed by a co-deposition method of an element which belongs to a 1 family or a 2 family of the periodic table and aluminum, or a laminated film of these) which is formed by a deposition method which used resistance heating. In addition, a cathode may be formed by using a sputtering method. In addition, in case of fabricating a upper surface launching type light emitting device, it is desirable that a cathode is transparent or semi-transparent, and it is desirable that a thin film (1 nm-10 nm) of the above-described metal film, or a laminated layer of a thin film (1 nm-10 nm) of the above-described metal film and a transparent conductive film is used as the cathode. In this case, by using a sputter method, a film, which comprising a transparent conductive film (ITO(indium oxide-tin oxide alloy), indium oxide-zinc oxide alloy (In2O3�ZnO), zinc oxide (ZnO) etc.), may be formed in the film forming chamber 1009. By the above-described processes, a light emitting device of a laminated layer configuration is formed. In addition, it may be designed that it is transferred to the film forming chamber 1013 which was coupled to the transfer chamber 1004 a, and a protective film, which comprises a silicon nitride film, or a silicon nitride oxide film, is formed for sealing. Here, in the film forming chamber 1013, a target which comprises silicon, or a target which comprises silicon oxide, or a target which comprises silicon nitride, is provided. For example, using the target which comprises silicon, by changing film forming chamber atmosphere to nitrogen atmosphere or atmosphere which includes nitrogen and argon, it is possible to form a silicon nitride film on a cathode. In addition, it may be formed by use of a thin film in which carbon is a major component (a DLC film, a CN film, an amorphous carbon film) as a protective film, and a film forming chamber which used a CVD method may be disposed separately. Then, a substrate, on which a light emitting device was formed, is transferred from the transfer chamber 1004 a to the hand-over chamber 1011, without contact with atmospheric air, and further, transferred from the hand-over chamber 1011 to the transfer chamber 1014. Then, the substrate, on which a light emitting device was formed, is transferred from the transfer chamber 1014 to the sealing chamber 1016. A seal substrate is set from outside to the load chamber 1017, and prepared. In passing, in order to remove an impurity such as moisture, it is preferable to carry out anneal in advance in vacuum. And, in case of forming a seal member for gluing the substrate on which a light emitting device was formed with the seal substrate, the seal member is formed in the sealing chamber, and the seal substrate, on which the seal member was formed, is transferred to the seal substrate stock chamber 1030. In passing, in the sealing chamber 1018, a drying agent may be disposed on the seal substrate. In passing, here, an example, in which the seal member was formed on the seal substrate, was shown, but in particular, it is not restrictive, and the seal member may be formed on the substrate on which a light emitting device was formed. Then, the sealing chamber 1016, the substrate and the seal substrate are glued together, and UV rays are irradiated to a pair of the glued substrates by a ultraviolet ray irradiating mechanism which was disposed in the sealing chamber 1016, to cure the seal member. In passing, here, as the seal member, ultraviolet ray cured resin was used, but if it is an adhesive agent, it is not particularly restrictive. Then, the pair of glued substrates are transferred from the sealing chamber 1016 to the transfer chamber 1014, and then, from the transfer chamber 1014 to the pull-out chamber 1019, and then, pulled out. As above, by using the manufacturing apparatus shown in FIG. 14, until a light emitting device is completely sealed in a hermetically enclosed space, it is not needed to be exposed to atmospheric air, and therefore, it becomes possible to fabricate a light emitting apparatus with high reliability. In passing, in the transfer chambers 1014, vacuum, and nitrogen atmosphere with atmospheric pressure are repeated, but it is desired that vacuum is maintained on a steady basis in the transfer chambers 1002, 1004 a. In passing, although it is not shown in the figure here, disposed is a control control apparatus for realizing automation by controlling a path through which the substrate is moved to an individual processing chamber. In addition, in the manufacturing apparatus shown in FIG. 14, the substrate, on which a transparent conductive film (or a metal film (TiN)) was disposed as an anode, is carried in, and a layer including an organic compound was formed, and thereafter, a transparent or semi-transparent cathode (e.g., a laminated layer of a thin metal film (Al, Ag) and a transparent conductive film) is formed, and thereby, it is also possible to form a upper surface launching type light emitting device. In addition, in the manufacturing apparatus shown in FIG. 14, the substrate, on which a transparent conductive film was formed as an anode, is transferred, and after a layer including an organic compound was formed, a cathode, which comprises a metal film (Al, Ag), is formed, and thereby, it is also possible to form a lower surface launching type light emitting device. In addition, it is possible to freely combine this embodiment with any one of the embodiment modes 1 through 4, the embodiment 1. Industrial Applicability According to this invention, it is possible to form a high-density organic compound layer, by carrying out deposition of an organic compound film over introducing material gas, and by having a component of the material gas included in the organic compound film, and by carrying out film formation up to a desired film thickness. According to this invention, by intentionally introducing material gas at the time of film formation, a high-density film is realized, and an impurity such as oxygen and moisture, which causes deterioration, is blocked from being intruded, or diffused in a film.
