[0001]    This application claims the priority and the benefit of Korea Patent Application No. 10-2010-012617 filed on Feb. 11, 2010, U.S. patent application Ser. No. 12/774,217 filed on May 5, 2010, and Korea Patent Application No. 10-2010-056716 filed on Jun. 15, 2010, the entire contents of which is incorporated herein by reference as if fully set forth herein. 
     
    
     BACKGROUND 
       [0002]    1. Field of the Invention 
         [0003]    Embodiments of this invention relate to a capacitive type touch screen panel and a method of manufacturing the same. 
         [0004]    2. Discussion of the Related Art 
         [0005]    Along with the development of the electronics industry, display devices, such as a liquid crystal display, an electroluminescent display, and a plasma display panel having a quick response speed, low power consumption, and an excellent color reproduction rate, have been in the spotlight. The display device is used for various electronic products such as televisions, monitors for computers, notebook computers, mobile telephones, display units for refrigerators, personal digital assistants, automated teller machines, and the like. In general, the display device interfaces with various input devices such as a keyboard, a mouse, and a digitizer. However, when a separate input device such as a keyboard, a mouse, or digitizer is used, a user is required to know how to use the separate input device, and as the separate input device occupies space, customer dissatisfaction is increased. Therefore, need for a convenient and simple input device that can reduce erroneous operation is needed. Also, there is a need for a touch screen panel in which a user can input information by directly contacting a screen with a finger or a pen. 
         [0006]    Because the touch screen panel has a simple configuration, which minimizes erroneous operations, the user can perform an input action without a separate input device, and can quickly and easily manipulate through contents displayed on a screen. 
         [0007]    Touch screen panels are classified into a resistive type, a capacitive type, an electromagnetic type according to a detection method of a touched portion. The resistive type touch screen panel determines a touched position by a voltage gradient according to a change of resistance in a state that a DC voltage is applied to metal electrodes formed on an upper plate or a lower plate. The capacitive type touch screen panel senses a touched position according to a difference in capacitance created in an upper or lower plate when the user physically contacts with a conductive film formed on the upper or lower plate. The electromagnetic type touch screen panel detects a touched portion by reading an LC value induced as an electromagnetic pen touches a conductive film. 
         [0008]    Hereinafter, a conventional capacitive type touch screen panel will be described with reference to  FIGS. 1 and 2 .  FIG. 1  is a top plan view illustrating a conventional capacitive type touch screen panel, and  FIG. 2  is a cross-sectional view illustrating the touch screen panel taken along line I-I′ and line II-II′ of  FIG. 1 . 
         [0009]    Referring to  FIGS. 1 and 2 , the conventional capacitive type touch screen panel includes an electrode forming part  20 , a routing wire forming part  40 , a pad forming part  60 , and a protective layer  50 . 
         [0010]    The electrode forming part  20  is formed on a substrate  10  and includes a plurality of first electrodes  21  arranged in parallel in a first direction (for example, an X-axis direction) and a plurality of second electrodes  22  arranged to intersect in a direction (for example, an Y-axis direction) perpendicular to the first electrodes  21 . The first electrodes  21  and the second electrodes  22  intersect to each other, but sustain an electrical insulation state by an insulation film  30 . Further, neighboring first electrodes  21  arranged in the first direction are connected to each other by a bridge  41 . That is, the bridge  41  connects the neighboring first electrodes  21  to each other through contact holes  30   a  and  30   b  formed in the insulation film  30  covering the first and second electrodes  21  and  22 . 
         [0011]    The routing wire forming part  40  is formed on the substrate  10  at positions outside the electrode forming part  20  and includes a plurality of first routing wires  42  connected to the plurality of first electrodes  21 , respectively, and a plurality of second routing wires  43  connected to the plurality of second electrodes  22 , respectively. 
         [0012]    The pad forming part  60  includes a plurality of first pads  61  connected to the plurality of first electrodes  21  through the plurality of first routing wires  42 , respectively, and a plurality of second pads  62  connected to the plurality of second electrodes  22  through the plurality of second routing wires  43 , respectively. 
         [0013]    The protective layer  50  covers the electrode forming part  20  and the routing wire forming part  40  and prevents the first and second electrodes  21  and  22  and the first and second routing wires  42  and  43  from being exposed to the outside environment. 
         [0014]    Hereinafter, a method of manufacturing a conventional capacitive type touch screen panel will be described with reference to  FIGS. 3A to 3D . 
         [0015]    Referring to  FIG. 3A , a first conductive layer for forming first and second electrodes is deposited on the substrate  10  including an electrode forming part  20 , a routing wire forming part  40 , and the pad forming part  60  through a deposition process such as a sputtering method. As the first conductive layer, an indium tin oxide (ITO) layer is generally used. After a photoresist is coated on the substrate  10  on which the first conductive layer is formed, a first photoresist pattern for exposing the first conductive layer is formed in the electrode forming part  20  by performing a photolithography process using a first mask. After removing the first conductive layer exposed by the first photoresist pattern through wet etching, a plurality of first electrodes  21  and a plurality of second electrodes  22  intersecting the first electrodes  21  are formed on the substrate  10  by ashing the remaining first photoresist pattern. 
         [0016]    Referring to  FIG. 3B , after the first insulation film  30  is formed on the substrate  10  in which the plurality of first and second electrodes  21  and  22  are formed, the first insulation film  30  of the pad forming part  60  and the routing wire forming part  40  is removed and first and second contact holes  30   a  and  30   b  penetrating the first insulation film  30  of the electrode  20  are formed with a photolithography process and an etching process using a second mask. The first and second contact holes  30   a  and  30   b  expose a portion of the neighboring first electrodes  21 . The first insulation film  30  includes silicon nitride, silicon oxide, or organic resin. 
         [0017]    Referring to  FIG. 3C , a second conductive layer is formed on an entire surface of the substrate  10  in which the first and second contact holes  30   a  and  30   b  are formed through a deposition process such as a sputtering method. The second conductive layer includes aluminum (Al) or molybdenum (Mo). After coating a photoresist on the substrate in which the second conductive layer is formed, first and second routing wires  42  and  43  are formed in a routing wire forming portion on the substrate  10  and a connection electrode  41  is formed on the first insulation film  30  of the electrode forming part  20  by performing a photolithography process and an etching process using a third mask. The connection electrode  41  connects the neighboring first electrodes  21  to each other through the first and second contact holes  30   a  and  30   b  formed in the first insulation film  30 . 
         [0018]    Referring to  FIG. 3D , after a second insulation film  50  as a protective film is formed on an entire surface of the substrate  10  in which the connection electrode  41  and the first and second routing wires  42  and  43  are formed, a through hole  50   a  for penetrating the second insulation film  50  is formed to expose the first and second routing wires  42  and  43  of the pad  60  with a photolithography process and an etching process using a fourth mask. 
         [0019]    However, the conventional capacitive type touch screen panel is manufactured with 4 mask processes, as described above, and each mask process accompanies a photolithography process requiring a series of continuous processes, such as photoresist (PR), coating, alignment, exposure, development, and cleaning, and thus it is necessary to reduce a number of a mask process. Further, because the first insulation film of an intersecting portion of the first electrode and the second electrode has a wide area and uses silicon nitride, silicon oxide, or organic resin, there is a problem that the first insulation film is viewed or apparent from the outside due to a color difference between the first insulation film and a periphery thereof. Further, the second insulation film formed as a protective film at the top of the touch screen panel is made of the same material as that of the first insulation film, and adhesive strength is weakened by gas used when depositing the first and second insulation films, and thus surface hardness is weakened. Therefore, after a touch screen panel is manufactured, when a next process of forming a display device is performed, an additional problem of a scratch occurs.  FIG. 4  is a drawing illustrating states before and after performing a scratch test of the touch screen panel manufactured in the related art, wherein the left picture illustrates a state before a scratch test and the right picture illustrates a state after a scratch test. 
       SUMMARY 
       [0020]    In one embodiment, a touch screen panel improves productivity by reducing a process tact time through reducing the number of mask process steps. 
         [0021]    In another embodiment, a touch screen panel solves a visibility problem occurring due to a color difference between a first insulation layer for covering a first electrode, and a second electrode used as a touch electrode, which has a wider area and a periphery thereof.

     DETAILED DESCRIPTION 
       [0056]    Hereinafter, example of various embodiments will be described in detail with reference to  FIGS. 5 to 26 . Like reference numerals designate like elements throughout the specification. 
         [0057]    An electrostatic capacitive touch screen panel according to a first embodiment of this invention will be described with reference to  FIGS. 5 and 6 .  FIG. 5  is a top plan view illustrating the touch screen panel according to the first embodiment of this invention, and  FIG. 6  is a cross-sectional view illustrating the touch screen panel taken along line I-I′ and line II-II′ of  FIG. 5 . 
         [0058]    Referring to  FIGS. 5 and 6 , the touch screen panel according to the first embodiment of this invention includes an electrode forming part A, a routing wire forming part B, and a pad forming part C. 
         [0059]    The electrode forming part A includes a plurality of first electrode serials  130  optionally arranged in parallel in a first direction (for example, an X-axis direction) and a plurality of second electrode serial  135  optionally arranged in parallel in a second direction (for example, an Y-axis direction) to intersect with the first direction. The first electrode serials  130  may also be referred to as first serial electrodes  130  because of their serial or linear repeating pattern of polygonal element. Similarly, the second electrode serials  135  may also be referred to as second serial electrodes  135  because of their serial or linear repeating pattern of polygonal elements. Each of the first electrode serials  130  includes first electrode patterns  131  having a triangle, a rectangle, a square, a quadrangle, a diamond shape, a polygonal shape, and the like, and first connection patterns  110  for connecting neighboring first electrode patterns  131 . Any suitable shape of the elements of the first electrode pattern  131  may be used. Each of the second electrode serials  135  includes second electrode patterns  136  having a triangle, a rectangle, a square, a quadrangle, a diamond shape, a polygonal shape, which may be similar to the first electrode patterns  131  and second connection patterns  137  for connecting neighboring second electrode patterns  136 . Any suitable shape of the elements of the second electrode pattern  136  may be used. 
         [0060]    In the first embodiment of this invention, the first connection patterns  110  are formed separately from the first electrode patterns  131 , and the second connection patterns  137  are integrally formed with the second electrode patterns  136 . Alternatively, the first connection patterns  110  may be integrally formed with the first electrode patterns  131 , and the second connection patterns  137  may be formed separately from the second electrode patterns  136 . 
         [0061]    The routing wire forming part B is formed on the substrate  100  at positions outside the electrode forming part A, and includes a plurality of first routing wires  112  connected to the plurality of first electrode serials  130 , respectively and a plurality of second routing wires  114  connected to the plurality of second electrode serials  135 , respectively. 
         [0062]    The pad forming part C includes a plurality of first pads  116  connected to the plurality of first electrode serials  130  through the plurality of first routing wires  112 , respectively, and a plurality of second pads  118  connected to the plurality of second electrode serials  135  through the plurality of second routing wires  114 , respectively. 
         [0063]    In the first embodiment of this invention, the first connection patterns  110 , and the first and second routing wires  112  and  114  are formed on a substrate  100  through a same process and are made of a same material. In other embodiments, the first connection patterns  110 , and the first and second routing wires  112  and  114  may be formed of different materials. Each of the first connection patterns  110  and the first and second routing wires  112  and  114  include one of Al, AlNd, Mo, MoTi, Cu, CuOx and Cr. Because these materials have a low resistivity, it is possible to lower contact resistance between the first and second electrode patterns  131  and  136  and the first connection pattern  110  or routing wires  112  and  114 . Because ITO has high resistivity and should have a thick thickness, it is difficult to use ITO as a routing wire, and thus ITO is not used in the first embodiment of this invention. However, the ITO may be used if desired. 
         [0064]    Further, it is preferable, though not necessary, that the first connection patterns  110  connecting the neighboring first electrode patterns are formed to have a thickness of about 2,000 Å to about 3,000 Å and a width of about 3 μm to about 10 μm. If a thickness of the first connection patterns  110  is less than 2,000 Å, the resistance of the first connection patterns  110  is high, and if a thickness of the first connection patterns  110  is larger than 3,000 Å, a step difference of a pattern increases. Also, if a width of the first connection patterns  110  is less than 3 μm, the resistance of the first connection patterns  110  is high, and if a width of the first connection patterns  110  is larger than 10 μm, the pattern may be visible. 
         [0065]    Further, in the first embodiment, because the first connection patterns  110  and the first and second routing wires  112  and  114  are formed through one same mask process, one mask process can be omitted, compared with the related art that forms a connection pattern for connecting electrode patterns and routing wires in a two mask processes. Accordingly, it is possible to reduce a cost and a tact time (manufacturing time required per product unit for achieving a daily production target amount). 
         [0066]    In the first embodiment of this invention, an insulation layer  120  is formed on the substrate  100  in which the first connection patterns  110  and the first and second routing wires  112  and  114  are formed, and in the insulation layer  120 , first and second contact holes  120   a  and  120   b  for exposing portions of each of the first connection patterns  110 , a third contact hole  120   c  for exposing one portion of the first routing wires  112  and a fourth contact hole  120   d  (see  FIG. 8A ) for exposing one portion of the second routing wires  114  are formed. The insulation layer  120  includes silicon nitride (SiNx). If a thickness of the insulation layer  120  is less than 5,000 Å, the insulation layer  120  may be destroyed or damaged by a voltage applied to the first electrode serial  130  and the second electrode serial  135 . Therefore, in order to prevent or reduce a phenomenon in which a failure occurs due to destruction or damage of the insulation layer  120  while using the touch screen panel, it is preferable, though not required, to form the insulation layer so that a thickness of the insulation layer is about 5,000 Å or more. 
         [0067]    Further, if a thickness of the insulation layer  120  is about 6,000 Å, a saturation state in which a transmittance no longer increases is observed and a color transition phenomenon becomes a minimum. That is, in view of a transmittance and chromaticity expression, when a thickness of the insulation layer  120  is 6,000 Å or more, a transmittance becomes a maximum and a color transition phenomenon becomes a minimum and thus it is most preferable that the insulation layer  120  has a thickness of 6,000 Å or more. However, if a thickness of the insulation layer  120  exceeds 7,000 Å, it is difficult to form a contact hole and more process time is required due to a characteristic of a silicon nitride layer used as a material of the insulation layer  120 . Therefore, when considering stability of the insulation layer  120 , a good light transmittance, and chromaticity expression ability together, it is most preferable, though not required, to form a thickness of the insulation layer  120  in a range of 5,000 Å to 7,000 Å, but it is possible to form a thickness of the insulation layer  120  in a range of 5,000 Å to 10,000 Å. 
         [0068]    Further, a plurality of first electrode serials  130  and a plurality of second electrode serials  135  are formed on the insulation layer  120  in which the first to fourth contact holes  120   a,    120   b,    120   c,  and  120   d  (see  FIG. 8A ) are formed. Each of the plurality of first electrode serials  130  includes a plurality of first electrode patterns  131  and is optionally arranged in a first direction (for example, an x-axis direction). Each of the plurality of second electrode serials  135  includes a plurality of second electrode patterns  136  and is optionally arranged in a second direction (for example, a y-axis direction) intersecting the first direction. Preferably, the first and second directions are perpendicular to each other, but may also intersect at an angle less than 90 degrees. Because the first electrode patterns  131  forming the first electrode serial  130  are separated from each other, the first electrode patterns  131  are connected to the portions of the first connection pattern  110  exposed through the first and second contact holes  120   a  and  120   b  formed in the insulation layer  120 , and the first electrode patterns  131  positioned at the outermost side are connected to the first routing wires  112  exposed through the third contact hole  120   c.    
         [0069]    As shown in  FIG. 6 , portions of the plurality of first electrode patterns  131  are formed in the contact holes  120   a,    120   b  and  120   c  so that the portions of the plurality of first electrode patterns  131  are partially filled in the contact holes  120   a ,  120   b  and  120   c.  For example, the portions of the plurality of first electrode patterns  131  are formed on side walls of the contact holes  120   a,    120   b  and  120   c,  and on exposed portions of the first connection patterns  110  and the first routing wires  112 . Accordingly, hollows or cavities  122   a,    122   b,  and  122   c  are respectively formed by the portions of the plurality of first electrode patterns  131  being partially filled in the contact holes  120   a,    120   b  and  120   c.    
         [0070]    The second electrode patterns  136  forming the second electrode serial  135  are integrally formed with the second connection patterns  137  and are connected to the second routing wires  114  exposed through the fourth contact hole  120   d  (see FIG.  8 A). The first and second electrode patterns  131  and  136  and the second connection patterns  137  are made of the same material through the same process. The first and second electrode patterns  131  and  136  and the second connection patterns  137  are made of a transparent metal material such as ITO or IZO. In the first embodiment, because the first and second electrode serials  130  and  135  and the second connection patterns  137  using ITO or IZO are formed in a top layer of the touch screen panel and ITO or IZO has very high hardness, a scratch does not occur in a subsequent process of forming a display device on the other surface of the substrate  100  of the touch screen panel, and thus a touch screen panel having a good quality is obtained. 
         [0071]    Hereinafter, a method of manufacturing a capacitive type touch screen panel according to the example embodiment of this invention will be described with reference to  FIGS. 7A to 9B . 
         [0072]      FIGS. 7A and 7B  are a top plan view and a cross-sectional view illustrating a first mask process in the method of manufacturing the touch screen panel according to the first embodiment of this invention. 
         [0073]    Referring to  FIGS. 5 ,  7 A, and  7 B, a first conductive pattern group including first connection patterns  110 , first routing wires  112 , and second routing wires  114  is formed on the substrate  100  including an electrode forming part A, the routing wire forming part B, and the pad forming part C using the first mask process. 
         [0074]    In more detail, a first conductive layer is entirely deposited on the substrate  100  through a deposition process such as a sputtering method. As the first conductive layer is patterned with a photolithography process and an etching process using a first mask, the first conductive pattern group including the first connection patterns  110 , the first routing wires  112 , and the second routing wires  114  is formed. Here, as a material forming the first conductive pattern group, Al, AlNd, Mo, MoTi, Cu, CuOx, Cr, ITO and so on are used. The first connection pattern  110  formed in the electrode forming part A (see  FIG. 5 ) is formed to have a thickness of about 2,000 Å to about 3,000 Å and a width of about 3 μm to about 10 μm. 
         [0075]    In another embodiment, the first conductive pattern group including the first connection patterns  110 , the first routing wires  112 , and the second routing wires  114  may be formed by being printed on the substrate  100 . Subsequent drying and/or heating process may be performed. In such a case, the photolithography process and the etching process using the first mask may be omitted. In other embodiments, other pattern forming processes may be used. 
         [0076]      FIGS. 8A to 8D  are a top plan view and cross-sectional views illustrating a second mask process in a method of manufacturing the touch screen panel according to the first embodiment of this invention. The first and second routing wires  112  and  114  indicated by dotted lines in  FIG. 8A  because they are covered by the insulation layer  120 , and the first and second routing wires  112  and  114  are portions that are not displayed in a top plan view, however for a better understanding, in this invention, the first and second routing wires  112  and  114  are indicated by dotted lines. 
         [0077]    Referring to  FIGS. 8A and 8B , the insulation layer  120  is formed through a deposition method such as sputtering on an entire surface of the substrate  100  in which the first conductive pattern group including the first connection patterns  110 , the first routing wires  112 , and the second routing wires  114  is formed. As a material of the insulation layer  120 , an inorganic insulation material such as silicon nitride (SiNx) is used. A thickness of the insulation layer  120  is preferably set to a range of about 5,000 Å to about 10,000 Å, more preferably, though not required, to a range of about 5,000 Å to about 7,000 Å. 
         [0078]    After the insulation layer  120  is formed, as shown in  FIG. 8C , a photoresist pattern  1000  is formed on a portion in which the insulation layer  120  should exist by a photolithography process using a second mask. First to fourth contact holes  120   a ,  120   b,    120   c  and  120   d  (see  FIG. 8A ) penetrating the insulation layer  120  are formed with a dry etching process using the photoresist pattern  1000 . Next, when the photoresist pattern  1000  is removed, as shown in  FIG. 8D , first to fourth contact holes  120   a,    120   b,    120   c  and  120   d  for exposing the first conductive pattern group  110 ,  112  and  114  are formed. Here, the first contact hole  120   a  exposes a portion of the first connection pattern  110 , the second contact hole  120   b  exposes another portion of the first connection pattern  110 , the third contact hole  120   c  exposes a portion of the first routing wire  112 , and the fourth contact hole  120   d  (see  FIG. 8A ) exposes a portion of the second routing wire  114 . 
         [0079]    In the first embodiment of this invention, a cross section that is perpendicular to an axial direction of at least one of the first to fourth contact holes  120   a,    120   b,    120   c,  and  120   d  may be any shape. A rectangular shape is shown in  FIG. 8A , but the first embodiment of the invention may include circular, oval, polygonal, or irregular shapes. Additionally, a depth of at least one of the hollows or cavities  122   a,    122   b,  and  122   c  may be about 2,000 Å to about 9,000 Å in the axial direction depending on a thickness of the insulation layer  120  and at thickness of the pluralities of first and second electrode patterns. 
         [0080]      FIGS. 9A to 9B  are a top plan view and a cross-sectional view illustrating a third mask process in the method of manufacturing the capacitive type touch screen panel according to the example embodiment of this invention.  FIG. 9A  is a top plan view illustrating the third mask process in the method of manufacturing the capacitive type touch screen panel according to the example embodiment of this invention, and for a better understanding, in  FIG. 9A , the insulation layer  120  formed between the first conductive pattern group and a second conductive pattern group which will be described later is not depicted. 
         [0081]    Referring to  FIGS. 9A and 9B , the second conductive pattern groups including a plurality of first electrode serials  130  and a plurality of second electrode serials  135  formed on the insulation layer  120  in which the first to fourth contact holes  120   a,    120   b,    120   c,  and  120   d  (see  FIG. 8A ) are formed using the third mask process. The plurality of first electrode serials  130  are optionally arranged in parallel in a first direction (for example, an x-direction). And the plurality of second electrode serials  135  are optionally arranged in parallel in a second direction (for example, a y-direction) intersecting the first direction. 
         [0082]    In more detail, a second conductive layer is deposited through a deposition process such as sputtering on an entire surface of the insulation layer  120  in which the first to fourth contact holes  120   a,    120   b,    120   c,  and  120   d  (see  FIG. 8A ) are formed. Thereafter, the second conductive layer is patterned with a photolithography process and an etching process using a third mask to form the second conductive pattern group including a plurality of first electrode serials  130  arranged parallel in the first direction (for example, an x-direction) and a plurality of second electrode serials  135  arranged parallel in the second direction (for example, an y-direction) intersecting the first direction. Here, each of the first electrode serials  130  includes the plurality of first electrode patterns  131 , and each of the second electrode serials  135  includes the plurality of second electrode patterns  136  and the second connection patterns  137  for connecting neighboring second electrode patterns  136 . As a material of the second conductive layer, ITO or IZO is used, and if a thickness thereof is about 1,200 Å to about 1,600 Å, a maximum transmittance can be obtained. 
         [0083]    Also, as shown in  FIG. 9B , portions of the plurality of first electrode patterns  131  are deposited in the contact holes  120   a,    120   b  and  120   c  so that the portions of the plurality of first electrode patterns  131  are partially filled in the contact holes  120   a,    120   b  and  120   c.  For example, portions of the plurality of first electrode patterns  131  are deposited on side walls of the contact holes  120   a,    120   b  and  120   c,  and on exposed portions of the first connection patterns  110  and the first routing wires  112 . Accordingly, hollows or cavities  122   a,    122   b,  and  122   c  are respectively formed by the portions of the plurality of first electrode patterns  131  being partially filled in the contact holes  120   a,    120   b  and  120   c.    
         [0084]    Here, each of the first and second electrode patterns  131  and  136  is formed in a triangle, a rectangle, a square, a quadrangle, a diamond, a polygon shape and so on, but a shape of the first and second electrode patterns  131  and  136  is not limited thereto and may include other random shapes. Further, in the first embodiment of this invention, the first electrode patterns  131  formed on the insulation layer  120  are separated, and the second electrode patterns  136  are integrally formed with t he second connection pattern  137 , but the first electrode patterns  131  may be integrally formed with a connection pattern on the insulation layer  120 , and the second electrode patterns  136  may be separated. In this later instance, the second electrode patterns are electrically connected by another connection pattern formed between the insulation layer and the substrate. 
         [0085]      FIG. 9C  is a cross-sectional view illustrating another touch screen panel obtained after second and third mask processes of processes of manufacturing the touch screen panel shown in  FIG. 5 . The touch screen panel shown  FIG. 9C  is similar to the touch screen panel shown in  FIG. 9B  excepting the first to fourth contact holes. In the touch screen panel shown in  FIG. 9B , the insulation layer  120  includes first and second contact holes  121   a  and  121   b  exposing portions of the first connection pattern  110 , third contact holes  121   c  exposing portions of the first routing wires  112 , and fourth contact holes (not shown) exposing portions of the second routing wire  114 . The first to fourth contact holes of the touch screen panel shown in  FIG. 9C  are different from that of touch screen panel shown in  FIG. 9C  in that inner walls of the first to fourth contact holes are slanted to a bottom of each contact holes. The slant angle of the contact hole has a range of about 30° to about 90°, but is not limited thereto and may be formed in the insulation layer  121 . 
         [0086]    As shown in  FIG. 9C , portions of the plurality of first electrode patterns  131  are deposited in the contact holes  121   a,    121   b  and  121   c  so that the portions of the plurality of first electrode patterns  131   a  are partially filled in the contact holes  121   a ,  121   b  and  121   c.  For example, portions of the plurality of first electrode patterns  131   a  are deposited on side walls of the contact holes  121   a,    121   b  and  121   c,  and on exposed portions of the first connection patterns  110  and the first routing wires  112 . 
         [0087]    Accordingly, hollows or cavities  123   a,    123   b,  and  123   c  are respectively formed by the portions of the plurality of first electrode patterns  131   a  being partially filled in the contact holes  121   a,    121   b  and  121   c.    
         [0088]    Next, a pad forming part C including a plurality of first pads  116  and a plurality of second pads  118  is formed. The plurality of first pads  116  are connected to the plurality of first electrode serials  130  through the plurality of first routing wires  112 , respectively, and the plurality of second pads  118  are connected to the plurality of second electrode serials  135  through the plurality of second routing wires  114 , respectively. 
         [0089]    According to the example embodiment of this invention, because the first connection patterns  110  and the first and second routing wires  112  and  114  are formed through the same process, at least one mask process may be omitted. Therefore, a cost can be reduced and a tact time can be reduced according to reduction of the number of masks. 
         [0090]    Further, in the first embodiment of this invention, because silicon nitride (SiNx) is used as the insulation layer  120 , a visibility problem occurring due to a color difference between the insulation layer  120  and a periphery thereof can be solved or reduced. Because a thickness of the insulation layer  120  is set to a range of 5,000 Å to 10,000 Å, a transmittance becomes a maximum and a color transition phenomenon becomes a minimum and thus a destruction or damage phenomenon of the insulation layer  120  can be suppressed. Therefore, stability of the touch screen panel can be remarkably improved. 
         [0091]    An electrostatic capacitive touch screen panel according to a second embodiment of this invention will be described with reference to  FIGS. 10 and 11 .  FIG. 10  is a top plan view illustrating the touch screen panel according to the second embodiment of this invention, and  FIG. 11  is a cross-sectional view illustrating the touch screen panel taken along line III-III′ and line IV-IV′ of  FIG. 10 . 
         [0092]    Referring to  FIGS. 10 and 11 , the touch screen panel according to the second embodiment of this invention includes an electrode forming part A, a routing wire forming part B, and a pad forming part C. 
         [0093]    The electrode forming part A includes a plurality of first electrode serials  230  optionally arranged in parallel in a first direction (for example, an X-axis direction) and a plurality of second electrode serial  235  optionally arranged in parallel in a second direction (for example, an Y-axis direction) to intersect with the first direction. Each of the first electrode serials  230  includes first electrode patterns  231  having a triangular shape, a rectangular shape, a square shape, a quadrangle shape, a diamond shape, a polygon shape, and so on, and first connection patterns  210  for connecting neighboring first electrode patterns  231 . Each of the second electrode serials  235  includes second electrode patterns  236  having a triangular shape, a rectangular shape, a square shape, a quadrangle shape, a diamond shape, a polygon shape, and so on, similar to the first electrode patterns  131  and second connection patterns  237  for connecting neighboring second electrode patterns  236 . 
         [0094]    In the second embodiment of this invention, the first connection patterns  210  are formed separately from the first electrode patterns  231 , and the second connection patterns  237  are integrally formed with the second electrode patterns  236 . Alternatively, the first connection patterns may be integrally formed with the first electrode patterns, and the second connection patterns may be formed separately from the second electrode patterns. 
         [0095]    The routing wire forming part B is formed on the substrate  200  at positions outside the electrode forming part A, and includes a plurality of first routing wires  212  connected to the plurality of first electrode serials  230 , respectively and a plurality of second routing wires  214  connected to the plurality of second electrode serials  235 , respectively. 
         [0096]    The pad forming part C includes a plurality of first pads  216  connected to the plurality of first electrode serials  230  through the plurality of first routing wires  212 , respectively, and a plurality of second pads  218  connected to the plurality of second electrode serials  235  through the plurality of second routing wires  214 , respectively. 
         [0097]    In the second embodiment of this invention, the first connection patterns  210 , and the first and second routing wires  212  and  214  are formed on a substrate  200  through a same process and are made of a same material. In other embodiments, the first connection patterns  210 , and the first and second routing wires  212  and  214  may be formed of different materials. Each of the first connection patterns  210  and the first and second routing wires  212  and  214  includes one of Al, AlNd, Mo, MoTi, Cu, CuOx and Cr. Because these materials have a low resistivity, it is possible to lower contact resistance between the first and second electrode patterns  231  and  236  and the first connection pattern  210  or routing wires  212  and  214 . Because ITO has high resistivity and should have a thick thickness, it is difficult to use ITO as a routing wire, and thus ITO is not used in the second embodiment of this invention. However, the ITO may be used if desired. 
         [0098]    Further, it is preferable, though not necessary, that the first connection patterns  210  connecting the neighboring first electrode patterns  231  are formed to have a thickness of about 2,000 Å to about 3,000 Å and a width of about 3 μm to about 10 μm. If a thickness of the first connection patterns  210  is less than 2,000 Å, the resistance of the first connection patterns  210  is high, and if a thickness of the first connection patterns  210  is larger than 3,000 Å, a step difference of a pattern increases. Also, if a width of the first connection patterns  210  is less than 3 μm, the resistance of the first connection patterns  210  is high, and if a width of the first connection patterns  210  is larger than 10 μm, the pattern is visible. 
         [0099]    Further, in the second embodiment of this invention, because the first connection patterns  210  and the first and second routing wires  212  and  214  are formed through one same mask process, one mask process can be omitted, compared with the related art that forms the first connection pattern for connecting the first electrode patterns and the routing wires in a two mask processes. Accordingly, it is possible to reduce a cost and a tact time. 
         [0100]    In the second embodiment of this invention, first insulation patterns  220   a  are formed in the electrode forming part A to expose a first and second portions  210   a  and  210   b  of the first connection patterns  210  and to insulate the first connection patterns  210  from the second connection patterns  237 . Each of the first electrode patterns  231  includes a first portion  231   a  formed on a first portion  210   a  of the first connection pattern  210 , a second portion  231   b  formed on a second portion  210   b  of the first connection pattern  210  and a middle portion  231   c  formed on the substrate  200 . Accordingly, neighboring first electrode patterns  231  are electrically connected to each other by the connection patterns  210 . In the  FIG. 11 , the first and second portions  231   a  and  231   b  of the first electrode pattern  231  are formed on the first and second portions  212   a  and  212   b  of the first connection pattern  212  and side wall and upper surface of the insulation pattern  220   b,  but this invention is not limited thereto. For example, the first and second portions  231   a  and  23  lb of the first electrode pattern  231  may be formed on the first and second portions  212   a  and  212   b  of the first connection pattern  212  or the first and second portions  212   a  and  212   b  of the first connection pattern  212  and the side wall of the insulation pattern  220   b.  However, if the first and second portions  231   a  and  231   b  of the first electrode pattern  231  are formed on the first and second portions  210   a  and  210   b  of the first connection pattern  210  and side wall and upper surface of the first insulation pattern  220   a  as shown in  FIG. 11 , a process margin which corresponds to a length from the side wall and the upper surface of the first insulation pattern  220   a  can be secured. Accordingly, although misalignment exists at a process of patterning the first and second electrode patterns  231  and  236 , it is possible to appropriately assure electrical contact between the first electrode patterns  231  and the first connection pattern  210 . 
         [0101]    In the second embodiment of this invention, second insulation patterns  220   b  are formed in the routing wire forming part B to expose a portion  212   a  of the first routing wire  212  and a portion (not shown) of the second routing wire  214 . The second portion  231   b  of the first electrode pattern  231  at outmost of the electrode forming part A is formed on a portion  212   a  of the first routing wire  212  and side wall and upper surface of the second insulation pattern  220   b.  A portion of the second electrode pattern  236  at outmost of the electrode forming part A is also formed on a portion (not shown) of the second routing wire  214  and side wall and upper surface of the second insulation pattern  220   b.    
         [0102]    Also, as shown in  FIG. 11 , any insulation pattern is not formed on first and second pads  216  and  218  so that they are electrically connected to external circuits. However, it is possible to form insulation patterns on the first and second pads  216  and  218  if the insulation pattern is formed on them and the insulation pattern has contact holes to expose portions of the first and second pads  216  and  218 . 
         [0103]    The first and second insulation patterns  220   a  and  220   b  includes silicon nitride (SiNx). If a thickness of the first insulation pattern  220   a  is less than 5,000 Å, the first insulation pattern  220   a  may be destroyed or damaged by a voltage applied to the first electrode serial  230  and the second electrode serial  235 . Therefore, in order to prevent or reduce a phenomenon in which a failure occurs due to destruction or damage of the first insulation pattern  220   a  while using the touch screen panel, it is preferable, though not required, to form the first insulation pattern  220   a  so that a thickness of the insulation pattern  220   a  is about 5,000 Å or more. Further, if a thickness of the first insulation pattern  220   a  is about 6,000 Å, a saturation state in which a transmittance no longer increases is observed and a color transition phenomenon becomes a minimum. That is, in view of a transmittance and chromaticity expression, when a thickness of the first insulation pattern  220   a  is 6,000 Å or more, a transmittance becomes a maximum and a color transition phenomenon becomes a minimum and thus it is most preferable that the first insulation pattern  220   a  has a thickness of 6,000 Å or more. However, if a thickness of the first insulation pattern  220   a  exceeds 7,000 Å, it is difficult to remove a portion of insulation layer  220  in the electrode forming part A, and much more process time is required due to a characteristic of a silicon nitride layer used as a material of the insulation layer  220 . Therefore, when considering stability of the insulation layer  220 , a good light transmittance, and chromaticity expression ability together, it is most preferable, though not required, to form a thickness of the first insulation pattern  220   a  in a range of 5,000 Å to 7,000 Å, but it is possible to form a thickness of the insulation layer  220  in a range of 5,000 Å to 10,000 Å. 
         [0104]    The first and second electrode patterns  231  and  236  and the second connection patterns  237  are made of the same material through the same process. The first and second electrode patterns  231  and  236  and the second connection patterns  237  are made of a transparent metal material such as ITO or IZO. In the second embodiment of this invention, because the first and second electrode serials  230  and  235  and the second connection patterns  237  formed on a top layer of the touch screen panel are made of ITO or IZO, and ITO or IZO has very high hardness, a scratch does not occur in a subsequent process of forming a display device on the other surface of the substrate  200  of the touch screen panel, and thus a touch screen panel of a good quality is obtained. 
         [0105]    Hereinafter, a method of manufacturing the touch screen panel according to the second embodiment of this invention will be described with reference to  FIGS. 12A to 14B . 
         [0106]      FIGS. 12A and 12B  are a top plan view and a cross-sectional view illustrating a first mask process in the method of manufacturing the touch screen panel according to the second embodiment of this invention. 
         [0107]    Referring to  FIGS. 10 ,  12 A, and  12 B, a first conductive pattern group including first connection patterns  210 , first routing wires  212 , second routing wires  214 , lower patterns  216   a  of first pads and lower patterns  218   a  of second pads is formed on the substrate  200  which includes an electrode forming part A, a routing wire forming part B and a pad forming part C using the first mask process. 
         [0108]    In more detail, a first conductive layer is deposited on the substrate  200  through a deposition process such as a sputtering method. As the first conductive layer is patterned with a photolithography process and an etching process using a first mask, the first conductive pattern group including the first connection patterns  210 , the first routing wires  212 , the second routing wires  214 , the lower patterns  216   a  of the first pads and the lower patterns  218   a  of the second pads is formed. Here, as a material forming the first conductive pattern group, Al, AlNd, Mo, MoTi, Cu, CuOx, Cr and so on are used. The first connection pattern  210  formed in the electrode forming part A (see  FIG. 10 ) is formed to have a thickness of about 2,000 Å to about 3,000 Å and a width of about 3 μm to about 10 μm. 
         [0109]    In another embodiment, the first conductive pattern group including the first connection patterns  210 , the first routing wires  212 , the second routing wires  214 , the lower patterns  216   a  of the first pads and the lower patterns  218   a  of the second pads may be formed by being printed on the substrate  200 . Subsequent drying and/or heating process may be performed. In such a case, the photolithography process and the etching process using the first mask may be omitted. In other embodiments, other pattern forming processes may be used. 
         [0110]      FIGS. 13A to 13D  are a top plan view and cross-sectional views illustrating a second mask process in a method of manufacturing the touch screen panel according to the second embodiment of this invention. The first and second routing wires  212  and  214  are indicated by dotted lines in  FIG. 13A . The first and second routing wires  212  and  214  are portions that are not displayed in a top plan view because they are covered by the second insulation pattern  220   b,  however for a better understanding, in this invention, the first and second routing wires  212  and  214  are indicated by dotted lines. 
         [0111]    Referring to  FIGS. 13A and 13B , the insulation layer  220  is formed through a deposition method such as sputtering on an entire surface of the substrate  200  on which the first conductive pattern group including the first connection patterns  210 , the first routing wires  212 , the second routing wires  214 , the lower patterns  216   a  of the first pads and the lower patterns  218   a  of the second pads is formed. As a material of the insulation layer  220 , an inorganic insulation material such as silicon nitride (SiNx) is used. A thickness of the insulation layer  220  is preferably set to a range of about 5,000 Å to about 10,000 Å, more preferably, though not required, to a range of about 5,000 Å to about 7,000 Å. 
         [0112]    After the insulation layer  220  is formed, as shown in  FIG. 13C , a photoresist pattern  1100  is formed on a portion in which the insulation layer  220  should exist by a photolithography process using a second mask. First and second insulation patterns  220   a  and  220   b  are formed with a dry etching process using the photoresist pattern  1100  as shown in  FIG. 13D . The first insulation patterns  220   a  are formed on the first connection patterns  210  and the substrate  200  in the electrode forming part A to expose a first portion  210   a  and a second portion  210   b  of the first connection patterns  210 . The second insulation pattern  220   b  is formed on the first and second routing wires  212  and  214  and the substrate  200  in the routing wire forming part B to expose a portion  212   a  of the first routing wire  212  and a portion (not shown) of the second routing wire  214 . In the second embodiment of this invention, the lower patters  216   a  and  218   a  of the first and second pads are exposed, but this invention is not limited thereto. In another embodiment, it is possible to form the second insulation pattern on the lower patters  216   a  and  218   a  of the first and second pads  216  and  218  if the second insulation pattern has contact holes to expose the lower patters  216   a  and  218   a  of the first and second pads  216  and  218 . 
         [0113]      FIGS. 14A to 14B  are a top plan view and a cross-sectional view illustrating a third mask process in the method of manufacturing the touch screen panel according to the second embodiment of this invention.  FIG. 14A  is a top plan view illustrating the third mask process in the method of manufacturing the touch screen panel according to the second embodiment of this invention, and for a better understanding, in  FIG. 14A , the second insulation pattern  220   b  formed in the routing forming area B is not depicted. 
         [0114]    Referring to  FIGS. 14A and 14B , the second conductive pattern groups including a plurality of first electrode serials  230 , a plurality of second electrode serials  235 , upper patterns  216   b  of the first pads, and upper patterns  218   b  of the second pads is formed on the substrate  222  on which the first connection patterns  210 , the first and second routing wires  212  and  214 , the lower patterns  216   a  and  218   a  of the first and second pads, and the first and second insulation patterns  220   a  and  220   b  are formed using the third mask process. The plurality of first electrode serials  230  are optionally arranged in parallel in a first direction (for example, an x-direction). And the plurality of second electrode serials  235  are optionally arranged in parallel in a second direction (for example, a y-direction) intersecting with the first direction. 
         [0115]    In more detail, the second conductive layer is deposited on an entire surface of the substrate  200  through a deposition process such as sputtering. On the substrate  200 , the first connection patterns  210 , the first and second routing wires  212  and  214 , the lower patterns  216   a  and  218   a  of the first and second pads, and the first and second insulation patterns  220   a  and  220   b  are formed. Thereafter, the second conductive layer is patterned with a photolithography process and an etching process using a third mask to form the second conductive pattern group including the plurality of first electrode serials  230  arranged in parallel in the first direction, the plurality of second electrode serials  235  arranged in parallel in the second direction intersecting with the first direction, the upper patterns  216   b  of the first pads, and the upper patterns  218   b  of the second pads. Here, each of the first electrode serials  230  includes the plurality of first electrode patterns  231 , and each of the second electrode serials  235  includes the plurality of second electrode patterns  236  and the second connection patterns  237  for connecting neighboring second electrode patterns  236 . As a material of the second conductive layer, ITO or IZO is used, and if a thickness thereof is about 1,200 Å to about 1,600 Å, a maximum transmittance can be obtained. 
         [0116]    As a result of the third mask process, in the electrode forming part A, the first portion  231   a  of the first electrode pattern  231  is formed on the first portion  210   a  of the first connection pattern  210 , the second portion  231   b  of the first electrode pattern  231  is formed on the second portion  210   b  of the first connection pattern  210 , and the middle portion  231   c  of the first connection pattern  210  is formed on the substrate  200 . Accordingly, the neighboring first electrode patterns  231  are electrically connected to each other by the first connection pattern  210 . In  FIG. 14B , the first and second portions  231  a and  231  b of the first electrode pattern  231  are formed on the first and second portions  210   a  and  210   b  of the first connection pattern  210 , and the upper surface and side wall of the first insulation pattern  220   a , respectively. However, this invention is not limited thereto, the first and second portions  231   a  and  231   b  of the first electrode pattern  231  may be formed on only the first and second portions  210   a  and  210   b  of the first connection pattern  210 , otherwise on the first and second portions  210   a  and  210   b  of the first connection pattern  210  and the side wall of the first insulation pattern  220   a,  respectively. 
         [0117]    In the routing wire forming part B, the second insulation pattern  220   b  is formed on the first routing wires  212  and the substrate  200  to expose the portion  212   a  of the first routing wire  212  and a portion (not shown) of the second routing wire  214 . The second portion  231   b  of the first electrode pattern  231  at outmost of the electrode forming part A is also formed on the portion  212   a  of the first routing wire  212  and the side wall and upper surface of the second insulation pattern  220   b . However, this invention is not limited thereto, the second portion  231   b  of the first electrode pattern  231  at outmost of the electrode forming part A may be formed on only the portion  212   a  of the first routing wire  212 , otherwise on the portion  212   a  of the first routing wire  212  and the side wall of the second insulation pattern  220   b , respectively. 
         [0118]    In the pad forming part C, the upper pattern  216   b  and  218   b  of the first and second pads are formed on the lower patterns  216   a  and  218   a  so that the upper patterns  216   b  and  218   b  surround the lower patterns  216   a  and  218   a,  respectively. In  FIG. 14B , any insulation pattern is not formed on first and second pads  216  and  218  so that they are electrically connected to external circuits. However, it is possible to form insulation patterns on the first and second pads  216  and  218  if the insulation pattern has contact holes to expose portions of the first and second pads  216  and  218 . 
         [0119]    An electrostatic capacitive touch screen panel according to a third embodiment of this invention will be described with reference to  FIGS. 15 and 16 .  FIG. 15  is a top plan view illustrating the touch screen panel according to the third embodiment of this invention, and  FIG. 16  is a cross-sectional view illustrating the touch screen panel taken along line V-V′ and line VI-VI′ of  FIG. 15 . 
         [0120]    Referring to  FIGS. 15 and 16 , the touch screen panel according to the third embodiment of this invention includes an electrode forming part A, a routing wire forming part B, and a pad forming part C. 
         [0121]    The electrode forming part A includes a plurality of first electrode serials  330  optionally arranged in parallel in a first direction (for example, an X-axis direction) and a plurality of second electrode serial  335  optionally arranged in parallel in a second direction (for example, an Y-axis direction) to intersect with the first direction. Each of the first electrode serials  330  includes first electrode patterns  331  having a triangle shape, a quadrangle shape, a diamond shape, a polygon shape, and so on, and first connection patterns  310  for connecting neighboring first electrode patterns  331 . Each of the second electrode serials  335  includes second electrode patterns  336  having a triangle shape, a quadrangle shape, a diamond shape, a polygon shape, and so on, similar to the first electrode patterns  331  and second connection patterns  337  for connecting neighboring second electrode patterns  336 . 
         [0122]    In the third embodiment of this invention, the first connection patterns  310  are formed separately from the first electrode patterns  331 , and the second connection patterns  337  are integrally formed with the second electrode patterns  336 . Alternatively, the first connection patterns may be integrally formed with the first electrode patterns, and the second connection patterns may be formed separately from the second electrode patterns. 
         [0123]    The routing wire forming part B is formed on the substrate  300  at positions outside the electrode forming part A, and includes a plurality of first routing wires  312  connected to the plurality of first electrode serials  330 , respectively and a plurality of second routing wires  314  connected to the plurality of second electrode serials  335 , respectively. 
         [0124]    The pad forming part C includes a plurality of first pads  316  connected to the plurality of first electrode serials  330  through the plurality of first routing wires  312 , respectively, and a plurality of second pads  318  connected to the plurality of second electrode serials  335  through the plurality of second routing wires  314 , respectively. 
         [0125]    The touch screen panel according to the third embodiment of this invention is different from those according to the first and second embodiments of this invention in that material used as the first connection patterns  310  is different from material used as the first and second routing wires  312  and  314 . In the third embodiment of this invention, the first and second routing wires  312  and  314  are formed of a single layer or multiple layers. For example, if the first and second routing wires  312  and  314  are formed of multiple layers, lower layers  312   a  and  314   a  may include one of Al, AlNd, Mo, MoTi, Cu, CuOx and Cr, and upper layers  312   b  and  314   b  may include one of ITO and IZO. The first connection patterns  310  may include a transparent conductive material such as ITO or IZO. Further, it is preferable, though not necessary, that the first connection patterns  310  are formed to have a thickness of about 2,000 Å to about 3,000 Å and a width of about 3 μm to about 10 μm. If a thickness of the first connection patterns  310  is less than 2,000 Å, the resistance of the first connection patterns  310  is high, and if a thickness of the first connection patterns  310  is larger than 3,000 Å, a step difference of a pattern increases. Also, if a width of the first connection patterns  310  is less than 3 μm, the resistance of the first connection patterns  310  is high, and if a width of the first connection patterns  310  is larger than 10 μm, the connection patterns  310  is visible. 
         [0126]    In the third embodiment of this invention, it needs four mask processes to manufacture the touch screen panel because material of the first connection patterns  310  is different from that of the first and second routing wires  312  and  314 . 
         [0127]    In the touch screen panel according to the third embodiment of this invention, first insulation patterns  320   a  are formed in the electrode forming part A to expose a first and second portions  310   a  and  310   b  of the first connection patterns  310  and to insulate the first connection patterns  310  from the second connection patterns  337 . Each of the first electrode patterns  331  includes a first portion  331   a  formed on a first portion  310   a  of the first connection pattern  310 , a second portion  331   b  formed on a second portion  310   b  of the first connection pattern  310  and a middle portion  331   c  formed on the substrate  300 . Accordingly, neighboring first electrode patterns  331  are electrically connected to each other by the connection patterns  310 . In the  FIG. 16 , the first and second portions  331   a  and  331   b  of the first electrode pattern  331  are formed on the first and second portions  310   a  and  310   b  of the first connection pattern  310  and side wall and upper surface of the first insulation pattern  320   a,  but this invention is not limited thereto. For example, the first and second portions  331   a  and  331   b  of the first electrode pattern  331  may be formed on only the first and second portions  310   a  and  310   b  of the first connection pattern  310 , respectively, otherwise on the first and second portions  310   a  and  310   b  of the first connection pattern  310  and the side wall of the insulation pattern  320   a.  However, if the first and second portions  331   a  and  331   b  of the first electrode pattern  331  are formed on the first and second portions  310   a  and  310   b  of the first connection pattern  310  and side wall and upper surface of the first insulation pattern  320   a  as shown in  FIG. 16 , a process margin which corresponds to a length from the side wall and the upper surface of the first insulation pattern  320   a  can be secured. Accordingly, although misalignment exists at a process of patterning the first and second electrode patterns  331  and  3236 , it is possible to assure electrical contact between the first electrode patterns  231  and the first connection pattern  210 . 
         [0128]    In the touch screen panel according to the third embodiment of this invention, first insulation patterns  320   a  are formed in the routing wire forming part B to expose a portion  312   a  of the first routing wire  312  and a portion (not shown) of the second routing wire  314 . The second portion  331   b  of the first electrode pattern  331  at outmost of the electrode forming part A is formed on a portion  212   a  of the first routing wire  212  and side wall and upper surface of the second insulation pattern  320   b.  A portion of the second electrode pattern  336  at outmost of the electrode forming part A is also formed on a portion (not shown) of the second routing wire  314  and side wall and upper surface of the second insulation pattern  320   b.  However, this invention is not limited thereto, the portion of the second electrode pattern  336  at outmost of the electrode forming part A may be formed on only the portion of the second routing wire  314 , otherwise on the portion of the second routing wire  314  and the side wall of the second insulation pattern  320   b,  respectively. 
         [0129]    Also, as shown in  FIG. 16 , any insulation pattern is not formed on first and second pads  316  and  318  in the pad forming part C so that they are electrically connected to external circuits. However, it is possible to form insulation patterns on the first and second pads  316  and  318  if the insulation pattern has contact holes to expose portions of the first and second pads  316  and  318 . 
         [0130]    The first and second insulation patterns  320   a  and  320   b  includes silicon nitride (SiNx). If a thickness of the first insulation pattern  320   a  is less than 5,000 Å, the first insulation pattern  320   a  may be destroyed or damaged by a voltage applied to the first electrode serial  330  and the second electrode serial  335 . Therefore, in order to prevent or reduce a phenomenon in which a failure occurs due to destruction or damage of the first insulation pattern  320   a  while using the touch screen panel, it is preferable, though not required, to form the first insulation pattern  320   a  so that a thickness of the insulation pattern  320   a  is about 5,000 Å or more. Further, if a thickness of the first insulation pattern  320   a  is about 6,000 Å, a saturation state in which a transmittance no longer increases is observed and a color transition phenomenon becomes a minimum. That is, in view of a transmittance and chromaticity expression, when a thickness of the first insulation pattern  320   a  is 6,000 Å or more, a transmittance becomes a maximum and a color transition phenomenon becomes a minimum and thus it is most preferable that the first insulation pattern  320   a  has a thickness of 6,000 Å or more. However, if a thickness of the first insulation pattern  320   a  exceeds 7,000 Å, it is difficult to remove a portion of insulation layer  320  in the electrode forming part A, and much more process time is required due to a characteristic of a silicon nitride used as a material of the insulation layer  320 . Therefore, when considering stability of the insulation layer  320 , a good light transmittance, and chromaticity expression ability together, it is most preferable, though not required, to form a thickness of the first insulation pattern  320   a  in a range of 5,000 Å to 7,000 °, but it is possible to form a thickness of the insulation layer  120  in a range of 5,000 Å to 10,000 Å. 
         [0131]    The first and second electrode patterns  331  and  336  and the second connection patterns  337  are made of a transparent conductive material such as ITO or IZO. In the third embodiment of this invention, because the first and second electrode serials  330  and  335  and the second connection patterns  337  formed on a top layer of the touch screen panel are made of ITO or IZO, and ITO or IZO has very high hardness, a scratch does not occur in a subsequent process of forming a display device on the other surface of the substrate  300  of the touch screen panel, and thus a touch screen panel of a good quality is obtained. 
         [0132]    Hereinafter, a method of manufacturing the touch screen panel according to the third embodiment of this invention will be described with reference to  FIGS. 17A to 20B . 
         [0133]      FIGS. 17A and 17B  are a top plan view and a cross-sectional view illustrating a first mask process in the method of manufacturing the touch screen panel according to the third embodiment of this invention. 
         [0134]    Referring to  FIGS. 15 ,  17 A, and  17 B, a first conductive pattern group including lower patterns  312   a  of first routing wires  312 , lower patterns  314   a  of second routing wires  314 , lower patterns  316   a  of first pads and lower patterns  318   a  of second pads is formed on the substrate  300  which includes an electrode forming part A, a routing wire forming part B and a pad forming part C using the first mask process. 
         [0135]    In more detail, a first conductive layer is deposited on the substrate  300  through a deposition process such as a sputtering method. As the first conductive layer is patterned with a photolithography process and an etching process using a first mask, the first conductive pattern group including the lower patterns  312   a  of the first routing wires  312 , the lower, patterns  314   a  of the second routing wires  314 , the lower patterns  316   a  of the first pads and the lower patterns  318   a  of the second pads is formed. Here, as a material forming the first conductive pattern group, Al, AlNd, Mo, MoTi, Cu, CuOx, Cr and so on are used. 
         [0136]    In another embodiment, the first conductive pattern group including the lower patterns  312   a  of the first routing wires  312 , the lower patterns  314   a  of the second routing wires  314 , the lower patterns  316   a  of the first pads and the lower patterns  318   a  of the second pads may be formed by being printed on the substrate  300 . Subsequent drying and/or heating process may be performed. In such a case, the photolithography process and the etching process using the first mask may be skipped. In other embodiments, other pattern forming processes may be used. 
         [0137]    Thereafter, through a deposition process such as a sputtering method, a second conductive layer is formed on the substrate  300  on which the first conductive pattern group is formed. As the second conductive layer is patterned with a photolithography process and an etching process using a second mask, a plurality of first connection patterns  310  are formed in the electrode forming part A. Also, in the routing wire forming part B, the upper patterns  312   b  of the first routing wires  312  are formed on the lower patters  312   a  of the first routing wires  312 , and the upper patterns (not shown) of the second routing wires  314  are formed on the lower patters  314   a  of the second routing wires  314 . Also in the pad forming part C, the upper patterns  316   b  of the first pads  316  are formed on the lower patterns  316   a  of the first pads  316 , and the upper patterns  318   b  of the second pad  318  are formed on the lower patterns  318   a  of the second pad  318 . The first connection pattern  310  formed in the electrode forming part A (see  FIG. 15 ) is formed to have a thickness of about 2,000 Å to about 3,000 Å and a width of about 3 μm to about 10 μm. 
         [0138]      FIGS. 19A to 19D  are a top plan view and cross-sectional views illustrating a third mask process in a method of manufacturing the touch screen panel according to the third embodiment of this invention. The first and second routing wires  312  and  314  are indicated by dotted lines in  FIG. 19A . The first and second routing wires  312  and  314  are portions that are not displayed in a top plan view because they are covered by the second insulation pattern  320   b,  however for a better understanding, in this invention, the first and second routing wires  312  and  314  are indicated by dotted lines. 
         [0139]    Referring to  FIGS. 19A and 19B , an insulation layer  320  is formed through a deposition method such as sputtering on an entire surface of the substrate  300  on which the conductive pattern group including the first connection patterns  310 , the first routing wires  312 , the second routing wires  314 , the first pads  316  and the second pads  318  is formed. As a material of the insulation layer  320 , an inorganic insulation material such as silicon nitride (SiNx) is used. A thickness of the insulation layer  320  is preferably set to a range of about 5,000 Å to about 10,000 Å, more preferably, though not required, to a range of about 5,000 Å to about 7,000 Å. 
         [0140]    After the insulation layer  320  is formed, as shown in  FIG. 19C , a photoresist pattern  1200  is formed on a portion in which the insulation layer  320  should exist by a photolithography process using a second mask. First and second insulation patterns  320   a  and  320   b  are formed in the electrode forming part A with a dry etching process using the photoresist pattern  1200  as shown in  FIG. 19D . The first insulation patterns  320   a  are formed on the first connection patterns  310  and the substrate  300  in the electrode forming part A to expose a first portion  310   a  and a second portion  310   b  of the first connection patterns  310 . The second insulation pattern  320   b  is formed on the first and second routing wires  312  and  314  and the substrate  300  in the routing wire forming part B to expose a portion of the first routing wire  312  and a portion (not shown) of the second routing wire  314 . The first and second pads  316  and  318  are formed in the pad forming part C to expose the upper patterns  316   b  and  318   b  of the first and second pads  316  and  318 . 
         [0141]      FIGS. 20A and 20B  are a top plan view and a cross-sectional view illustrating a fourth mask process in the method of manufacturing the touch screen panel according to the third embodiment of this invention.  FIG. 20A  is a top plan view illustrating the fourth mask process in the method of manufacturing the touch screen panel according to the third embodiment of this invention, and for a better understanding, in  FIG. 20A , the second insulation pattern  320   b  formed in the routing forming area B is not depicted. 
         [0142]    Referring to  FIGS. 20A and 20B , a second conductive pattern group including a plurality of first electrode serials  330  and a plurality of second electrode serials  335  is formed on the substrate  300  on which the first connection patterns  310 , the first and second routing wires  312  and  314 , the first and second pads  316  and  318 , and the first and second insulation patterns  320   a  and  320   b  are formed using the fourth mask process. The plurality of first electrode serials  330  a re optionally arranged in parallel in a first direction. And the plurality of second electrode serials  335  are optionally arranged in parallel in a second direction intersecting with the first direction. 
         [0143]    In more detail, a third conductive layer is deposited on an entire surface of the substrate  300  through a deposition process such as sputtering. On the substrate  300 , the first connection patterns  310 , the first and second routing wires  312  and  314 , the first and second pads  316  and  318 , and the first and second insulation patterns  320   a  and  320   b  are formed. Thereafter, the third conductive layer is patterned with a photolithography process and an etching process using a fourth mask to form the second conductive pattern group including the plurality of first electrode serials  330  arranged in parallel in the first direction and the plurality of second electrode serials  335  arranged in parallel in the second direction intersecting with the first direction. Here, each of the first electrode serials  330  includes the plurality of first electrode patterns  331 , and each of the second electrode serials  335  includes the plurality of second electrode patterns  336  and the second connection patterns  337  for connecting neighboring second electrode patterns  336 . As a material of the third conductive layer, ITO or IZO is used, and if a thickness thereof is about 1,200 Å to about 1,600 A, a maximum transmittance can be obtained. 
         [0144]    As a result of the fourth mask process, in the electrode forming part A, the first portion  331   a  of the first electrode pattern  331  is formed on the first portion  310   a  of the first connection pattern  310 , the second portion  331   b  of the first electrode pattern  331  is formed on the second portion  310   b  of the first connection pattern  310 , and the middle portion  331   c  of the first connection pattern  310  is formed on the substrate  300 . Accordingly, the neighboring first electrode patterns  331  are electrically connected to each other by the first connection pattern  310 . In  FIG. 20B , the first and second portions  331   a  and  331   b  of the first electrode pattern  331  are formed on the first and second portions  310   a  and  310   b  of the first connection pattern  310 , and the upper surface and side wall of the first insulation pattern  320   a , respectively. However, this invention is not limited thereto, the first and second portions  331   a  and  331   b  of the first electrode pattern  331  may be formed on only the first and second portions  310   a  and  310   b  of the first connection pattern  310 , otherwise on the first and second portions  310   a  and  310   b  of the first connection pattern  310  and the side wall of the first insulation pattern  320   a,  respectively. 
         [0145]    In the routing wire forming part B, the second insulation pattern  320   b  is formed on the first and second routing wires  312  and  314  and the substrate  300  to expose portions of the first and second routing wire  312  and  314 . The second portion  331   b  of the first electrode pattern  331  at outmost of the electrode forming part A is also formed on the portion of the first routing wire  312  and the side wall and upper surface of the second insulation pattern  320   b.  However, this invention is not limited thereto, the second portion  331   b  of the first electrode pattern  331  at outmost of the electrode forming part A may be formed on only the portion  312   a  of the first routing wire  312 , otherwise on the portion  312   a  of the first routing wire  312  and the side wall of the second insulation pattern  320   b,  respectively. 
         [0146]    In the pad forming part C, the upper pattern  316   b  and  318   b  of the first and second pads  316  and  318  are formed on the lower patterns  316   a  and  318   a  so that the upper patterns  316   b  and  318   b  surround the lower patterns  316   a  and  318   a , respectively. In  FIG. 20B , any insulation pattern is not formed on first and second pads  316  and  318  so that they are electrically connected to external circuits. However, it is possible to form insulation patterns on the first and second pads  316  and  318  if the insulation pattern has contact holes to expose portions of the first and second pads  316  and  318 . 
         [0147]    In the touch screen panel according to the third embodiment of this invention, the material used as the lower patterns  312   a  and  314   a  of the first and second routing wires  312  and  314  includes Al, AlNd, Mo, MoTi, Cu CuOx, or Cr, the material used as the upper patterns  312   b  and  314   b  of the first and second routing wires  312  and  314  includes a transparent conductive material such as ITO or IZO, and the material used as the first connecting patterns  310  includes the transparent conductive material such as ITO or IZO. However, this invention is not limited thereto. 
         [0148]    For example, as shown in  FIG. 20C , the material used as the lower patterns  312   a  and  314   a  of the first and second routing wires  312  and  314  may include Al, AlNd, Mo, MoTi, Cu, CuOx or Cr, the material used as the upper patterns  312   b  and  314   b  of the first and second routing wires  312  and  314  includes a transparent conductive material such as ITO or IZO, the material used as the lower patterns  311  a of the first connecting patterns  311  may includes include Al, AlNd, Mo, MoTi, Cu, CuOx or Cr, and the material used as the upper patterns  311   b  of the first connecting patterns  311  may include the transparent conductive material such as ITO or IZO. In this case, it is possible to reduce one mask process compared to the third embodiment because the first and second mask processes of the third embodiment can be performed by one mask process. 
         [0149]      FIGS. 21 to 23  are simulation graphs illustrating a breakdown voltage, a transmittance, and a color transition characteristic according to a thickness of silicon nitride in the touch screen panel formed by using ITO as the first and second electrode patterns and using silicon nitride as the insulation layer (or pattern). 
         [0150]      FIG. 21  is a graph illustrating an electric field value of a breakdown point in which an insulation layer is destroyed or damaged according to a thickness of silicon nitride used as the insulation layer when a thickness of ITO used as first and second electrode patterns is about 1,400 Å. In  FIG. 21 , a horizontal axis represents a thickness (A) of silicon nitride and a vertical axis represents intensity (MV/cm) of an electric field. As shown in  FIG. 21 , it is very important to appropriately adjust a thickness of silicon nitride because silicon nitride is destroyed or damaged when an electric field of 10 megavolt/cm or more is applied. In a condition in which a voltage (this value is a reliability condition of a touch screen panel manufacturer) of 500 volts or less is applied between the first and second electrode patterns  131  and  136  of the touch screen panel, when a thickness of silicon nitride is about 5,000 Å or less, insulation of silicon nitride was destroyed or damaged. Therefore, silicon nitride as the insulation layer should be formed in a thickness of 5,000 Å or more. 
         [0151]      FIG. 22  is a graph illustrating a transmittance of a touch screen panel according to a thickness of silicon nitride used as the insulation layer when a thickness of ITO using as the first and second electrode patterns is about 1,400 Å. In  FIG. 22 , a horizontal axis represents a thickness (A) of silicon nitride and a vertical axis represents a transmittance (%), “AIR” represents a transmittance of an instance in which a polarization sheet is not attached to the touch screen panel, and “POL” represents a transmittance of instance in which a polarization sheet is attached to the touch screen panel. As can be seen from  FIG. 22 , in a thickness of 5,000 Å or more in which the insulation layer is not destroyed or damaged, a transmittance gradually increases in a thickness of about 5,000 Å, arrives at a peak value in a thickness of about 6,000 Å, falls again to a thickness of about 6,500 Å, and increases again to a thickness of about 7,000 Å. That is, in an insulation layer thickness of 6,000 Å or more, because a transmittance is saturated, even if a thickness deviation occurs, there is no or little change of transmittance.  FIG. 22  shows that a single touch screen panel has a transmittance of about 89%, and when a polarization sheet is attached to the touch screen panel, a transmittance of about 93% was obtained. 
         [0152]      FIG. 23  is a graph illustrating a color transition characteristic of the touch screen panel according to a thickness of silicon nitride used as an insulation layer when a thickness of ITO used as first and second electrode patterns is 1,400 Å. In  FIG. 23 , a horizontal axis represents a thickness (A) of silicon nitride and a vertical axis represents a chrominance, “AIR” represents a chrominance of an instance in which a polarization sheet is not attached to the touch screen panel, and “POL” represents a chrominance of an instance in which a polarization sheet is attached to the touch screen panel. As can be seen from  FIG. 24 , similarly to an instance of a transmittance, in a thickness of 5,000 Å or more in which the insulation layer is not destroyed or damaged, a color transition characteristic is similar to a transmittance characteristic. 
         [0153]      FIGS. 24 and 25  are simulation graphs of a transmittance characteristic and a color transition characteristic according to a thickness of an ITO layer in the touch screen panel formed by using ITO as the first and second electrode patterns and using silicon nitride as an insulation layer. 
         [0154]      FIG. 24  is a graph illustrating a characteristic of transmittance according to a thickness of ITO used as the first and second electrode patterns when a thickness of silicon nitride formed as an insulation layer is 6,000 Å. In  FIG. 24 , a horizontal axis represents a thickness (Å) of an ITO layer, a vertical axis represents a transmittance (%), “AIR” represents a transmittance of an instance in which a polarization sheet is not attached to the touch screen panel, and “POL” represents a transmittance of an instance in which a polarization sheet is attached to the touch screen panel. As can be seen from  FIG. 24 , a thickness of silicon nitride is fixed to 6,000 Å and a light transmittance according to an ITO thickness has a minimum value in 700 Å and has a maximum value in 1400 Å. 
         [0155]      FIG. 25  is a graph illustrating a color transition characteristic according to a thickness of ITO used as first and second electrode patterns when a thickness of silicon nitride formed as an insulation layer is 6,000 Å. In  FIG. 25 , a horizontal axis represents a thickness (A) of an ITO layer and a vertical axis represents a chrominance, “AIR” represents a color transition degree of an example in which a polarization sheet is not attached to the touch screen panel, and “POL” represents a color transition degree of an instance in which a polarization sheet is formed in the touch screen panel. As can be seen from  FIG. 25 , when a thickness of silicon nitride is fixed to 6,000 Å and a color transition degree according to an ITO thickness is measured, the color transition degree has a minimum value in about 700 Å, and thus an optimum ITO thickness is obtained in about 100 Å or about 1400 Å. However, in a display of a notebook computer size or more, due to a resistance problem, an optimum ITO thickness is obtained in about 1400 Å. In a consideration of a thickness range of silicon nitride used in the example embodiment, when a thickness of ITO is about 1,200 ÅA to about 1,600 Å, a maximum transmittance is obtained. 
         [0156]    Further, in the example embodiment, because the first and second electrode serials and the second connection patterns are formed on a top layer of the touch screen panel, a scratch does not occur in a subsequent process. 
         [0157]      FIG. 26  is a drawing illustrating a result before and after performing a scratch test of an area A in which the top of a touch screen panel is an insulation layer and an area B in which the top of a touch screen panel is ITO. In the result after performing a scratch test, a scratch occurs in the area A of the insulation layer, but a scratch does not occur in the area B of ITO. 
         [0158]    Further, as a thickness of the first connection pattern formed between the insulation layer and the substrate to connect the first electrode patterns is formed in about 2,000 Å to about 3,000 Å, good process ability and an appropriate resistance value can be obtained, and as a width is set to a range of about 3 μm to about 10 μm, a pattern is not visible. 
         [0159]    The touch screen panels according to the embodiments of this invention may be applied to display devices such as a liquid crystal display, a field emission display, a plasma display panel, an electroluminescence device, an electrophoresis display and a flexible display. In these cases, the substrates of the touch screen panels may be also used as substrates of the display devices.
