Patent JP-H04112528-A (JP)
Title: Manufacture of semiconductor device
Inventor: FUJITA KOICHI
IPC: H01L21/336
Filed: 1990-08-31
Abstract: PURPOSE:To manufacture a high-performance element with good reliability by a method wherein a nitrifying treatment of the surface of a high-melting-point metal electrode in order to restrain the channeling of impurities is executed at a comparatively low temperature by using a vacuum discharge using a mixed gas of hydrogen and nitrogen. CONSTITUTION:A semiconductor substrate 1 to be processed is arranged in an apparatus system which is capable of executing a vacuum discharge. The apparatus system is evacuated to produce a vacuum. Then, the temperature of the substrate 1 as a whole is raised. Then, a mixed gas of hydrogen and nitrogen is made to flow into this vacuum system; electric power is applied; the vacuum discharge is generated. At this time, many hydrogen radicals and many nitrogen radicals are generated in this vacuum discharge system. When they react with the surface of an Mo gate electrode 3, a discharge nitride film 4 is formed. After the film 4 has been formed, the applied electric power is cut; the temperature of the semiconductor substrate is lowered to room temperature; a gas inside the vacuum system is replaced by nitrogen; the inside of the system is returned to atmospheric pressure; the semiconductor substrate is taken out. Then, impurities are implanted in a self-aligned manner by using the electrode 3 as a mask. Since a dense film 4 has been formed on the surface of the electrode 3 by the previous process, it is possible to restrain impurities from being implanted into the gate electrode 3, a gate oxide film 2 and the substrate 1.

Title: Color image reader
Inventor: NAGASAWA KIYOTO
IPC: H04N1/19
Filed: 1991-08-21
Abstract: PURPOSE:To simplify an optical system and a signal processing circuit. CONSTITUTION:A color image sensor 20 is provided with two sensors 21 and 22 extending in a main scanning direction, and the sensor 21 is not arranged with a color filter so as to read monochrome information. The other sensor 22 is provided with a red (R) filter and reads color information in which red information is erased. When the color image sensor 20 reads the same picture element of an original and when the output level of the monochrome sensor 21 is smaller than a white level and the output level of the red sensor 22 is equivalent to the white level, the picture element can be discriminated to be close to red. Since the output level of the red sensor 22 can be raised so that the red sensor 22 can read data at resolution equivalent to 1/2 of that of the monochrome sensor 21, the output level of the red sensor can be equalized to that of the monochrome sensor for the white color used as a basis by selecting the transparent factor of the filter.

Title: Defect repairing method for liquid crystal display device
Inventor: YOSHIMURA KAZUYA
IPC: G02F1/1333
Filed: 1992-09-01
Abstract: PURPOSE:To provide a defect repairing method of a display device in which the repaired part is not visualized as a shadow in the display device without spoiling the light transmitting property of a screen. CONSTITUTION:In a display device of which the screen is provided with a transparent plate, an ArF eximer laser beam 10 in which the size of a laser beam is changed is irradiated on a defect part on the screen. The laser beam 10 is irradiated so that the energy distribution is set high on the center part and low on the outer circumferential part. Hereby, an irradiated plane 2 which becomes gradually shallow from the center part toward the peripheral part, is formed. Hence, the contour of the irradiated part becomes indistinct, and a favorable worked face on which the contour is hardly visualized as a shadow, can be obtained. Further, because the ArF eximer laser is of short wave length, fine working of finer molecular order is possible, and variation of material due to heat is not caused. Thereby, the cutting face is very sharp so as not to generate a rough face. Consequently, working can be performed without spoiling the light transmitting property of the screen.
