Title: Processing method of semiconductor element substrate
Inventor: KITAGAWA MASATOSHI
IPC: H01L21/205
Filed: 1982-06-10
Abstract: PURPOSE:To easily form an insulating surface only to the necessary area of a stainless substrate by processing said stainless steel substrate under the plasma discharge ambient of gas including nitrogen element. CONSTITUTION:A stainless steel substrate 8 is held by a substrate holder 4 and it is exhausted from exhaustion hole 113, and thereafter the N2 gas is supplied up to a pressure of about 0.1-10Torr from a gas supply hole 2. At this time, the substrate is heated up to 150 deg.C by a heater. The area to be protected from insulation is placed in such a condition that the surface of substrate is isolated from the plasma by means of a metal mask etc. Thereafter, the nitrogen plasma is generated between the electrodes 4 and 5 by the power supply 6 and the surface of substrate 8 is exposed to the nitrogen plasma for about 10-330min. Accordingly, even when a thin film of Al etc. is vacuum-deposited at the insulated area, the stainless substrate and Al film are not electrically connected, sufficiently allowing the substrate to be used for extending a lead wire of a semiconductor device.

Title: Compensating circuit for voltage dependency of diffused resistance used for ic-implemented da converter
Inventor: MAIO KENJI
IPC: H03M1/78
Filed: 1981-07-01
Abstract: PURPOSE:To compensate the voltage dependency of a DA converter, by providing a current source, which supplies a current of an R-2R resistance network, with voltage dependency in the opposite direction to that of the R-2R resistance network. CONSTITUTION:As a power voltage V rises, the resistance value R of an R-2R resistance network 5 increases and an output voltage Vout drops. Then, a voltage applied to a resistance R4 also drops, so the resistance value of the resistance R4 decreases. Therefore, constant current sources 10-1n decrease in current value and the voltage drop across the R-2R resistance network 5 decreases and the output voltage Vout is compensated. The constant current sources 10-1n are driven by the reference voltage source consisting of a transistor 6 and an amplifier 3.
