Filed: 1988-07-28
Abstract: PURPOSE:To form a uniform and flat buried diffused layer having a uniform film thickness and avoid an edge effect by a method wherein a thick oxide film is formed by a selective oxidization method using a nitride film and a tapered aperture is formed by wet etching with the nitride film as a mask and a coating film containing impurity is formed. CONSTITUTION:A thin silicon oxide film 2 is formed on the surface of a P-type silicon substrate 1 and, further, a silicon nitride film 11 is formed. Then the nitride film 11 is patterned to form an aperture 3 on a region where a buried diffused layer is to be formed and a thick silicon oxide film 2a is formed by selective oxidization. At that time, the edge part of the thick oxide film 2a is tapered. Then a gently tapered aperture 3a is formed by wet etching. Then silicon compound solution containing high concentration N-type impurity is applied and subjected to a thermal treatment to form a silica film 4. The coverage of the silica film 4 is satisfactory and the thickness is nearly uniform. A thermal treatment is performed to form a buried diffused layer 5. After the silica film 4, the nitride film 11 and the oxide film are removed, an N-type epitaxial layer 6 is built up over the whole surface.

Title: Mask inspecting process
Inventor: MATSUMOTO TAKASHI
IPC: G03F1/84
Filed: 1983-10-12
Abstract: PURPOSE:To make a mask inspection easier reducing inspecting manhours by a method wherein overall surface of specimen to be exposed is exposed to detect any unexposed part as a foreign matter. CONSTITUTION:The light from a light source 1 is transmitted through an inspected mask 3 to expose a specimen 6 to be exposed by means of projecting the light transmitting the part excluding a light cut off pattern on the surface of the specimen 6 through a half-mirror 4 and an objective lens 5. On the other hand, the other light from another light source 11 hits the half-mirror 4 through a focussing lens 12 reflecting on the half-mirror 4 to enter into the surface of the inspected mask 3. Then the reflected light from the light cut off pattern on the mask 3 transmits the half-mirror 4 to be projected on the specimen 6 to be exposed through the objective lens 5 to expose the specimen 6. When the surface of the inspected mask 3 is irradiated by the light from the two light sources 1 and 11, the pattern is extinguished to expose the overall surface of the specimen 6 to be exposed. Through these procedures, any foreign matter sticked on the surface or backside of the inspected mask 3 may be detected as an unexposed part on the specimen 6 to be exposed.

IPC: C12N15/87
Filed: 1983-10-13
Abstract: PURPOSE:To insert a substance efficiently into a very large amount of live cells, by improving the surface conditions of the live cells by irradiation with laser beams to give a state for incorporating the substance, and associating the substance with the live cells in a medium containing the substance to be incorporated in the cells. CONSTITUTION:Live cells are perforated by irradiation with laser beams and then associated with a substance to be incorporated therein in a medium, e.g. a culture medium of the live cells, containing the substance to be incorporated therein. Thus, the above-mentioned substance is incorporated in the live cells, and holes are closed by the reparative function of the live cells to contain the substance in the holes of the live cells. A biopolymer, e.g. gene or protein, may be cited as the substance. The irradiation time of the laser beams must be adjusted not to kill the live cells in perforation by irradiation with the laser beams. As a means, the laser beams are shaped in the pulse form to limit the ir- radiation time.

Abstract: PURPOSE:To obtain the joined body with which O3 of high purity and high concn. is obtainable when said body is used for a water electrolysis type O3 producing device by disposing an aq. lead salt soln. to one surface of an ion exchange resin membrane and an aq. soln. of a hypochlorous acid oxidizing agent to the other surface, respectively, and depositing a plating layer of lead dioxide on one surface of said resin membrane. CONSTITUTION:Two chambers are provided with, for example, the cation exchange resin membrane between. The aq. lead salt soln. such as lead acetate is filled in one chamber and the aq. soln. of the hypochlorous acid such as NaClO is filled in the other chamber. The aq. soln. contg. lead ions comes into contact with the cation exchange resin membrane and the lead ions in the liquid penetrate selectively into the membrane when this state is maintained. The lead ions arrive at the opposite side where the ions are oxidized and are deposited as the lead dioxide. The O3 having the extremely high purity and high concn. as compared to the O3 obtd. by the conventional discharge system is obtd. by the above-mentioned O3 producing device constituted by applying the joined body of the ion exchange resin membrane and the lead dioxide electrode obtd. in such a manner. The size and weight of the O3 generator are, therefore, drastically reduced and the production cost of the device is reduced.

Title: Constant current source circuit
Inventor: NANBU HIROAKI
IPC: H01L27/10
Filed: 1986-08-18
Abstract: PURPOSE:To prevent the current of a current source from varying and to make the access time of a RAM constant by composing the 2nd constant voltage source of a level shift circuit which generates a voltage shifted in level from the voltage of the 1st constant voltage source. CONSTITUTION:A transistor (TR) Q2, diodes D2-D4, and a resistance R2 constitute the level shift circuit and generate a voltage which is shifted in level from the ground potential by a level shift quantity Vs at the emitter of the TR Q2. This level shift quantity Vs is Vd2+Vd3+Vd4-Vbe2, where Vd2-Vd4 are voltages of the diodes D2-D4 and Vbe2 is the base-emitter voltage of the TR Q2; and an external source voltage Vcc does not appear. If, however, the Vcc varies, the voltages Vd2-Vd4 vary actually. The voltages of the diodes are in logarithmic proportion to the current, so the level shift quantity Vs has a little variation although the external source voltage Vcc varies, and the current Ib of the constant current source does not vary and the access time of the RAM is made nearly constant.

Filed: 1982-11-01
Abstract: PURPOSE:To prevent noise with different in pulse width and to make advantageously a complex circuit constitution into IC formation by providing plural delay circuits different in delay time in an integrated circuit and selecting one of their outputs. CONSTITUTION:The delay circuits 21-2n having different delay times are provided and one of their outputs is selected by a selecting circuit 4 according to a control signal 5 and inputted to a deciding circuit 3 together with a direct input IN signal. The circuit 4 selects a delay circuit which prevents a noise sufficiently according to a normal signal and the pulse width of the noise. Namely, a delay time (t2''-t1'') is made shorter than the pulse width of the normal input signal and longer than the pulse width of the noise, so that the noise does not appear in a signal OUT since the signal IN is 0 at time t2''. Further, the delay time is shorter than the pulse width of the normal input signal and signals IN and DELAY are both 1 at time t5'', so the signal OUT is 1 continuously up to time t6'', so that the normal signal is outputted.

Abstract: PURPOSE:To prevent a cutter from rotating even if electric source has been left connected carelessly in a maintenance work of a crusher. CONSTITUTION:A crusher is provided with a fitting metal block 17 projecting from a crusher casing 9 and fixing an electric source cord side connector 15b and support rods 18 projecting from the crusher casing 9 and piercing in the penetrated holes 19 of a crusher motor 5a. When the crusher motor 5a is removed from the crusher casing 9 in the case of maintenance work of the crusher 5, since the fitting metal block 17 fastens the cord side connector 15b, it can not be removed unless it is pulled out of an electric source box side connector 15a. And even if the electric source cord side connector 15b is tried to remove from the fitting metal block 17, by trying to rotating the whole crusher motor 5a with hands against the crusher casing 9, the connector 15b is never removed owing to the support rods 18. Accordingly, when the crusher motor 5a is removed, the electric source must be disconnected inevitably and hence, safe operation can be performed.
