Patent JP-S6384138-A (JP)
Title: Manufacture of semiconductor device
Inventor: KOBAYASHI SHOGO
IPC: H01L23/52
Filed: 1986-09-29
Abstract: PURPOSE:To prevent step cutting due to erosion and splitting at slant parts, by performing heat treatment of molibdenum silicide which has been deposited by sputtering in an N2 atmosphere at 200-800 deg.C before an electrode layer is formed by using MoSi, and obtaining a desired pattern by dry etching. CONSTITUTION:An MOS transistor is formed by using MoSi as a gate electrode material. At this time, a thick field oxide film 8 is formed on an Si substrate 3. A thin gate oxide film 9, which is surrounded by the film 8, is formed. Namely, the film 8 having a thickness of 7,000Angstrom  is grown on the entire surface of the substrate 3 by a thermal oxidation method. A part corresponding to the film 9 is removed by wet etching. The film 9 having a thickness of 700Angstrom  is grown by thermal oxidation method again. Thereafter, an MoSi film 1 is deposited by sputtering to a thickness of about 4,000Angstrom  on the entire surface. Heat treatment is performed in an N2 atmosphere at 200-800 deg.C. The film 1 is divided into first and second electrode patterns 4 and 5 by dry etching using CF4+O2. Thus, step cutting between the patterns 4 and 5 can be prevented.
Patent JP-H0277764-A (JP)
Title: Voltage applying and exposing method
Inventor: OBATA HIROYUKI
IPC: G03G15/00
Filed: 1988-09-13
Abstract: PURPOSE:To enable voltage application and exposure with high sensitivity by interposing an insulator between a photosensitive body and a charge holding medium and preventing spark discharge between the photosensitive body and charge holding medium even when a high voltage is applied. CONSTITUTION:The charging holding medium 3 is set opposite the photosensitive body 1 at an interval of, for example, about 10mum and a power source 17 applies a voltage between electrodes 7 and 13. In a dark place, there is no change between the electrodes because a photoconductive layer 9 is a high resistance body. If light is made incident from the side of the photosensitive body 1, the photoconductive layer at the part where the light is made incident becomes conductive to cause discharge with an insulating layer 11, where charges are accumulated. Then when exposure is finished, the voltage is turned off and the charge holding medium 3 is taken out, thereby finishing the formation of an electrostatic latent image. Consequently, carrier generation efficiency at the time of the exposure is increased by raising the applied voltage to enable the voltage application and exposure with the high sensitivity.

If said information record exists, the buffer position information is returned to the process 61 to complete the processing. While the means 5d gives an access request to a system buffer control means 5b when the control information record does not exist.

Abstract: PURPOSE:To improve the talking quality by measuring a DC talking current to estimating an impedance of a two-wire talking line thereby selecting an optimum balance network constant at all times. CONSTITUTION:A voltage across a resistor 8 is measured by a buffer amplifier 8. A window comparator 11 has a different voltage range. When an impedance viewing a line 21 from a subscriber 30 is equal to an impedance of a balance network (BNW)3 corresponding to a closed analog switch 4, the bypass is minimized. A voltage ¦Va¦ is outputted from the amplifier 10 by a DC current of a DC loop. The DC resistance of the line 21 is calculated by the measurement of the output and the impedance ZL of the line 21 is estimated based on the calculation, the combined impedance is related to the ¦Va¦. 'n'-set of balance networks 3 are prepared based on the variable range of the estimated ZL. Thus, the output of the buffer amplifier 10 corresponds to the analog switch 4 by the window comparator 11, then the detour from a buffer amplifier 1 to an output V4 of a differential buffer amplifier 5 is minimized.
