Title: Power supply sequence circuit
Inventor: HAYASHI SHINICHI
IPC: G05F1/00
Filed: 1987-08-14
Abstract: PURPOSE:To surely control the power supply application sequence and to improve the power supply reliability with small power consumption, by using 1st and 2nd conduction path means using the optical coupling elements, a delay means, a control means for output power supply, etc. CONSTITUTION:When a negative power supply VIN2 is applied to an input power supply terminal 32, the output of a 3-terminal regulator 50 is kept at an earth level and therefore a light emitting diode 62 emits no light. Then an optically connected phototransistor Tr64 does not conduct and therefore an output power supply VEE is not delivered to an output terminal 38. When a positive power supply VIN1 is applied to an input terminal 30, the prescribed voltage VCC is delivered from an output terminal 36 via a regulator 50. The voltage VCC is also supplied to a delay circuit 12 and a voltage detecting circuit 14. Thus the diode 62 emits the light and the Tr64 conducts. Then the voltage VIN2 supplied to the terminal 32 is converted into the prescribed voltage VEE via a 3-terminal regulator 68 and delivered via the terminal 38. Thus it is possible to surely control the power supply application sequence and to improve the power supply reliability with small power consumption.

Abstract: PURPOSE:To prevent a characteristic from decreasing by forming sidewalls on the sides of the gate electrode of a MOS transistor by anisotropic etching, with an emitter electrode formed on the base region of a bipolar transistor. CONSTITUTION:A P type intrinsic base region 13 is formed on the surface of an N type epitaxial layer 4 and an N type emitter region 19 is formed on the surface of the P type intrinsic base region 13. A polycrystalline silicon film 23 is selectively etched to form a patterned emitter electrode 18 with a patterned photoresist film 20 just on the N type emitter region 19 used as a mask. Sidewalls 25a, 25b, and 25c are left on the sides of electrodes 18, 9, and 10 respectively by selectively removing silicon-dioxide films 24, 8a, and 8b by anisotropic etching with the photoresist film 20 and the emitter electrode 18 used as a mask. An N<+> type source-drain region and a P type base take out region are selectively formed. Thereby the characteristic of a p-n junction between the base and emitter regions is not deteriorated.
