Title: Composite type semiconductor device
Inventor: KUBO TAKEHARU
IPC: H03K17/56
Filed: 1993-02-26
Abstract: PURPOSE:To obtain a highly reliable composite type semiconductor device ensuring excellent breakdown resistance by adequately selecting an impedance value of a closed circuit formed between the gate and the cathode of an electrostatic induction type thyristor. CONSTITUTION:A gate current flowing during a turn-on period can change a conductive width of a gate by changing a floating inductance 8 thereof and therefore it is selected adequately. That is, an inductance value Lg of a closed circuit formed between the gate and the cathode of the electrostatic induction type thyristor is selected as satisfying the releationship, Lg>[{1/pi(Cg)<1/2>]<2>. In the period T0 where a gate current of the electrostatic induction type thyristor flows, an increase rate of an anode current is determined using a maximum amount of use setting the anode current of the electrostatic induction type thyristor to the rated value. Here, Cg designates a ratio between a charge accumulated in the gate layer under the forward inhibit condition of the electrostatic induction type thyristor and a gate-to-cathode voltage under the forward inhibit condition. Thereby, breakdown resistance can be improved.

Title: Object detecting device for vehicle
Inventor: TSURUTA MANABU
IPC: H01H36/00
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To easily keep an interval between sensor electrodes, and to install an object detecting device on a vehicle by a simple method by arranging an electrically grounded linear electrode on the earth side of a belt like electrode arranged in the bumper part of the vehicle. SOLUTION: When an obstacle approaches a sensor electrode (a belt-like electrode) 10a, impedance and secondary side capacity of a sensor electrode unit 10 change, so that an oscillating circuit makes input to a CPU according to a change in a generating oscillating level. The CPU actuates a buzzer and a warning lamp by outputting a signal to show the existence of the obstacle. The sensor electrode unit 10 is composed of the laterally long belt-like electrode 10a running along a bumper shape fixed to the inside of bumpers 30 of the vehicle front/rear parts by a fixing member 18 and a linear electrode 10c parallel to this. Since both electrodes 10a, 10c can be transformed into a sub-assembly by an ABS resin, a fluctuation in a detecting distance can be eliminated by always setting an interval constant. An object detecting device can be easily installed on a vehicle by a transformation of the sensor electrode unit 10 into the sub-assembly.

Abstract: PURPOSE:To contrive the reduction in MOS capacitance with simple construction by a method wherein the surface of a protection film formed on the surface of an oxide film on a semiconductor substrate is provided with an extension electrode. CONSTITUTION:The oxide film 4 is formed after formation of a base 2 and an emitter 3 in a wafer 1, and electrodes 5 and 6 are connected to the base 2 and the emitter 3 via apertures 4A and 4B bored in the film 4 thereafter. Afterwards, the protection film 7 is formed so as to cover the film 4 and the electrodes 5 and 6. Apertures 8 and 9 are provided at parts of the film 7 corresponding to the electrodes 5 and 6, respectively; extension electrode sections 5A and 6A connected to each of the electrodes 5 and 6 via these apertures are formed on the surface of the film 7. Such a manner makes the MOS capacitance equivalent to a series capacitance of the capacitance of the film 4 and that of the film 7. Since the capacitance becomes smaller than the capacitance of the film 4, the MOS capacitance reduces.
