Filed: 1984-10-15
Abstract: PURPOSE:To improve radiation resistance property of an electrically insulated isolating film, by alternately depositing a silicon oxide films and silicon nitride films, which are grown in a chemical phase, on a thermally oxidized silicon oxide film. CONSTITUTION:On the surface of a P type silicon semiconductor substrate, a patterned thin oxide film 102 and a silicon nitride film 103 are formed. Then, with the silicon nitride film 103 as a mask, ions of P type impurities such as boron are implanted 104 in an etched groove. Then a channel stopper region 105 is formed. A silicon oxide film 106 is further formed, and photoresist is applied. The silicon oxide film and the silicon nitride film undergo plasma etching. The silicon nitride film 102 is removed, with only a part of the etching groove made to remain. Finally, the entire surface is covered by a protecting insulating film made of phosphorus glass and the like. A source electrode 114 and a drain electrode 115 are formed. Thus an MOS transistor structure is completed. Leak currents between neighboring MOS transistors can be suppressed, and the radiation resistance property is improved to a large extent.

IPC: H03M5/20
Filed: 1984-10-15
Abstract: PURPOSE:To always hold the threshold value of a identifying circuit optimum by controlling the DC offset of the input signal of an A/D converter correctly. CONSTITUTION:A deciding circuit 26 inputs the low-order K bits of the output of the A/D converter 14 and decides whether the DC drift of the input signal is larger than a specific value or not. Then, a feedback signal generating circuit 43 outputs the 1st high-order bit among the low-order bits when it is judged that the input signal is controlled with the output of the circuit 26 and the DC drift is smaller than the specific value or outputs at least one of the high- order M bits of the converter 14 when it is decided that the DC drift is larger than the specific value. This output signal is sent to an LPF21 and a feedback signal is sent to a DC amplifier 12 from the LPF so that the DC offset of the multilevel input signal is controlled so as to reduce the DC drift.
