摘要:
On a silicon substrate, a first insulation layer, a lower conductive layer, a capacitor-insulator layer, and an upper conductive layer are formed in that order. Then, a first resist pattern is formed, the upper conductive layer is etched to form an upper electrode, and the capacitor-insulator layer is successively etched partway under the same etching condition as that of the upper conductive layer. Next, second resist pattern is formed, the remaining part of the capacitor-insulator layer is etched to form a second insulation layer, and the lower conductive layer is successively etched under the same etching condition as that of the capacitor-insulator layer so as to form a lower electrode and a lower wiring. In this manner, an MiM capacitor element constituted by the upper electrode, a part of the second insulation layer, and the lower electrode can be fabricated.

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.

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.

Provided is a battery having a high charging/discharging capacity density as compared with a conventional one. The battery (1) is characterized by comprising a positive electrode (2), a negative electrode (3), and an electrolytic solution interposed between the positive electrode (2) and the negative electrode (3) and formed by dissolving an electrolytic solution in a solvent, wherein the positive electrode (2) includes rubeanic acid or a rubeanic acid derivative as an active material and the solvent includes an ionic liquid. In the battery (1), it is possible to neutralize, by anions present in the ions, positive charges generated when rubeanic acid or the rubeanic acid derivative is oxidized. Therefore, rubeanic acid or the rubeanic acid derivative can take three states from an oxidant to a reductant, so that a high charging/discharging capacity density can be obtained in comparison with a conventional one.
