摘要:
An amplifying device for setting input impedance at several GΩ to several tens of GΩ and improving an ESD withstand current rating is provided.An ECM is connected to an input terminal 21 and frequency characteristics become flat to a voice band by high input impedance of a CMOS amplifier 20 and the input impedance is set at several GΩ to several tens of GΩ and thereby, response time after detecting a loud voice or turning on a power source of the ECM is speeded up and desired electrical characteristics are achieved. A path for releasing a surge voltage which occurs during assembly in the outside of an IC and intrudes from the input terminal 21 to a power source terminal or an earth terminal without an influence on a signal (20 Hz to 20 kHz) of a voice band entering from the input terminal 21 can be constructed by connecting a P-channel MOS transistor 27 and an N-channel MOS transistor 28 as an ESD protective element.

In conventional processes, a recombination rate of minority carrier accumulated between a diffusion layer of an anode and a diffusion layer of a cathode cannot be enhanced. An interlayer insulating film 20 is formed on a semiconductor substrate 10. An opening 22 (first opening), an opening 24 (second opening) and an opening 26 are formed in the interlayer insulating film 20. The opening 22 and the opening 26 are formed above respective the p-type diffusion layer 16 and the n-type diffusion layer 18. The opening 24 is formed above the gap region that is a region between the p-type diffusion layer 16 and the n-type diffusion layer 18. A contact plug 32, a contact plug 34 and a contact plug 36 are embedded in the opening 22, the opening 24 and the opening 26 respectively. Both regions of the semiconductor substrate 10 located under the opening 22 among and located under the opening 24 are doped with an impurity.

To reduce the ratio of the area of a diode region relative to the chip area. A semiconductor device comprises an insulated gate transistor formed on a substrate 1, a plurality of diodes D1, D2, and D3 formed on the substrate 1 and connected in serial between the gate of the insulated gate transistor and a terminal, and a diode array that breaks down when a surge voltage from the terminal is applied. The diode array is formed on the P-type substrate 1 and the diodes D1, D2, and D3 respectively has a plurality of N-type wells 2a, 2b, and 2c, which serve as cathodes. The sizes of spaces S1 between the N-type wells 2a and 2b, and S2 between the N-type wells 2b and 2c are different.

A pressure supply network for an active suspension system employs a strategy for predicting consumed fluid flow rate on the basis of bounding and rebounding stroke between a vehicular body and a suspension member rotatably supporting a vehicular wheel. A discharge rate of a fluid pump disposed in the pressure supply network is controlled on the basis of the predicted fluid flow rate.

A hydraulic pressure supply system includes a discharge rate variable fluid pump. The discharge rate of the fluid pump is controlled to vary depending upon the vehicle driving condition. In the control of the discharge rate of the fluid pump, greater discharge rate is ordered while the vehicle is running, than that during vehicle stopping condition.
