Title: Nondirect driving igbt
Inventor: SENDA KATSUNORI
IPC: H01L29/78
Filed: 1991-09-19
Abstract: PURPOSE:To eliminate the need for insulating a driving power supply of each gate driving circuit and to unify a driving power supply by changing a gate driving system to an optical system and by driving a gate of an IGBT directly by light which is led by a light guide, etc. CONSTITUTION:A part which was conventionally covered with an emitter electrode 10 of a cell structure of an IGBT is removed and a photosensitive window is provided to a gate electrode by making a gate insulating film transparent. When light which is led by a light guide, etc., is irradiated to a photosensitive window part of the gate electrode, electrons are driven out of a region n2 of the IGBT. The electrons are captured and stored by a gate electrode 9, make the gate electrode 9 negatively charged and turn on the IGBT. When irradiation of light is ceased, electrons stored in the gate electrode 9 discharge quickly through a resistance 5 and the IGBT turns off. Thereby, it is possible to eliminate the need for insulating a driving power supply of each gate driving circuit and to unify a driving power supply. Furthermore, an effect to acquire stable operation is produced.

This liquid becomes fine mist and this fine mist is diffused in the air introduced by the blower 21 and introduced into a separator 22 from a feed port 25. The air mixed with fine mist introduced into the separator 22 becomes a turning flow. Fine mist large in particle diameter collides against the inner circumferential wall surface of the separator 22. This fine mist returns into the tank 2 via a return pipe 12 from a drain port 26. The mixed air contg. superfine mist less than 0.5mum is introduced into a clean room 29 via a duct 28 from an exhaust port 27.
