Title: Vertical power mosfet and manufacture thereof
Inventor: DOURA SHOJI
IPC: H01L29/78
Filed: 1995-06-26
Abstract: PURPOSE: To suppress the generation of a Zener diode leak due to the shortage of diffusion by a method wherein the film of the polysilicon of a P<+> region is thinned off by etching the surface of the P<+> region of a Zener diode part. CONSTITUTION: After an N<-> region 10 has been formed in an N-type body 8, the area, excluding the part which becomes the P<+> region of a Zener diode, is covered by a resist 11, and a polysilicon is etched. P-type impurities can be implanted into the P<+> region of the Zener diode under the above-mentioned condition. By etching only the part which becomes the P<+> region of the Zener diode on the polysilicon 7, the film of the polysilicon of the above-mentioned part can be made thinner than the other part. As a result, P<+> type impurities can be diffused sufficiently on the P<+> region.

Filed: 1984-08-31
Abstract: PURPOSE:To detect an abnormal operation of a head effectively by monitoring a flowing direction of a gain control signal to detect whether a gain control means carries out a gain control or not. CONSTITUTION:A gain control signal S (A, G, C) outputted from an addition amplifier circuit 12 is applied to a signal line feeding back to A, G, C amplifier 4 inserting a resistance 14, both side voltages of the resistance 14 are compared by a voltage comparator 15 and a flowing direction of the gain control signal S flowing through the resistance 14 is detected. When the signal S flows from the A, G, C amplifier 4 to an addition amplifier circuit 12 side, the A, G, C amplifier 4 does not do the gain control and a servo head 2 can be judged to be placed in an erase zone. Thereby, since a reference voltage is not required to be set, an abnormal position of the head can be detected without relating to the characteristics of a servo disk 1, a servo head 2, a preamplifier 3 and the like.

Abstract: PURPOSE:To preclude misrecognition in a fault diagnosis under the inhibition state of an actuator by providing a detecting means for the control inhibition state of electronic control systems by a control unit and a means which indicates the detection result on a tester side. CONSTITUTION:This device is equipped with the control inhibition state detecting means for the on-vehicle electronic control systems 61 - 6X by the control unit ECU 2 and the means which indicates the detection result on the side of the tester 1. Then when the control inhibition state of actuators 61 - 6X is stored on a memory 20 and an operation/stop control command is sent out, it is retrieved and confirmed whether the command is ON or not. Judging means 10 or/and 21 judge whether the control is inhibited or not from the detection result of a sensor 5. When a test signal 11 is sent to the ECU, the memory 20 is retrieved and when the control is inhibited, the signal is sent back to the tester 1. When the control is not inhibited, on the other hand, the actuators are operated and controlled. Consequently, the control inhibition state of the actuators are also detected and it is decided whether a control disabled state is caused by the fault of the control system side or the control inhibition state, thereby precluding the misrecognition.
