Title: Formation of silicon oxide film
Inventor: UEDA HIROICHI
IPC: H01L21/316
Filed: 1989-07-07
Abstract: PURPOSE:To decrease the OH component in a silicon oxide film and to decrease the amount of film contraction by depositing the silicon oxide film by a CVD method using tetraethoxysilane and ozone, and thereafter performing annealing treatment in an ozone atmosphere or in oxygen plasma continuously. CONSTITUTION:After the deposition of a silicon oxide film, O3 is made to flow by about 3,000 SCCM or more for about 5-10 minutes in the same chamber, or the film is left alone in O2 plasma discharge. Temperature is set at 430 deg.C (the higher the temperature, the better the quality). For example, the OH component which remains in the silicon oxide film becomes smaller than he component of the film which does not undergo O3 annealing by about 10% at the ratio of O-H/Si-O (spectrum intensity ratio in FT-IR analysis) by the O3 annealing. The film contracting rate before and after the annealing in the N2 atmosphere at 900 deg.C is improved by about 9% in comparison with the values of (film thickness before annealing-film thickness after annealing)/(film thickness before annealing)X100.

Abstract: PURPOSE:To eliminate yield reduction in steel plate rolling by setting an edge clearance of a shearing device having upper and lower blades capable of overlapping and vertically movable to a specified dimension or less in cutting off hot steel pieces such as continuous casting slab. CONSTITUTION:When 800 deg.C or more hot steel pieces are cut off by a shearing device having upper and lower blades sandwiching a steel plate slab, they are shorn with a edge clearance set from 0 to 0.5 or less. Thereafter, burrs on a lap fracture or the like produced in a section are removed. For example, assuming that an edge clearance between upper and lower blades capable of overlapping and engaging each other is set to 0.03mm and 0.45mm, the contour of shorn section cut off from a continuous casting slab has 23, 25, 27mm of sag length 11c, 223, 218, 214mm of shorn surface length 12c, 4, 7, 9mm of fracture length 13c and 3mm of lap length 14c. Also, since the shorn burrs from lap, fracture, etc. causing flaws generated on the steel plate are made extremely small, they can be easily removed to reduce yield loss.

Abstract: PURPOSE:To display a grasping power value when grasping a grip holder and an integrated grasping power value, etc., on a display by counting a pulse, etc., by grasping a first grip holder and a second grip holder against a spring, and outputting a prescribed number of pulses corresponding to the amount of travel by the relative approach of both holders. CONSTITUTION:When the grip holders 1, 4 are grasped upward/downward against the power of the spring, the grip holders 1, 4 approach each other, and a rack gear body 7 is moved upward for a gear 8, therefore, the gear 8 is rotated corresponding to the amount of travel of the gear body. When the gear 8 is rotated in a clockwise direction, no gear 9 is rotated since a clutch off state is set. When a rotor 23 is rotated, an alternating field is generated in stators 20, 21, and an AC signal with frequency in accordance with the rotating speed of the rotor is generated in a coil 22. When a pair of magnetic poles of an rotor 23 are prepared, a signal of 1Hz per revolution of the rotor is generated. The only signal with polarity on one side of the AC signal outputted from the coil 22 is supplied to the base circuit of a transistor by a diode D1, then, it is amplified. Thereby, the number of pulses in accordance with the relative amount of travel of two grip holders can be generated by a waveform shaping circuit, etc.

Abstract: PURPOSE:To increase the withstand voltage of the titled device by a method wherein a surge-resisting protective transistor is connected in parallel to the circuit to be protected, and when the circuit consisted of an emitter follower circuit, an emitter area is provided at 200mum<2> or more, and in the case other than the above, the area is set at 90mum<2> or more. CONSTITUTION:A protective transistor Q1, wherein the base is open-circuited and connected to the emitter through the intermediary of a resistor, is connected in between the internal output terminal 4 of a logic circuit 3 and a power source terminal 5. The breakdown voltage VBR of the transistor Q1 is in proportion to the square of 1/2 of the emitter area AE. When the voltage VBR required to protect the IC under the environment wherein it is used, is estimated, 550V is obtained for the circuit such as an ECL which includes an emitter follower, and 450V is obtained for a TTL and the like which includes no emitter follower. When the area AE, corresponding to the voltage VBR 550V and 450V under the above-mentioned proportional relations, is calculated, 200mum<2> and 90mum<2> are obtained respectively. Accordingly, if the emitter area is provided larger than these values, the withstand voltage for a surge input can be improved.
