Abstract
PURPOSE:To provide a positive prevention of damage of insulation in all gate oxidation films by a method wherein a yield junction voltage generated among a power supply, a drain electric pole and a substrate plate is set lower than an insulating breaking voltage in the gate oxidation film. CONSTITUTION:Withstand voltage in the parasitic diode caused by p<+>n junction between a source electrode 22 or a drain electrode 23 in all MOSFET 24a, 24b connected to the power supply terminal 12 and the output terminal and Si base plate 28 of different polarity, and n<+>p junction with p area 29 is set lower than the insulative breakdown voltage. A concentration degree of impurities Nt at a high specific resistance producing yield voltage at the junction is derived separately and a concentration degree of impurities at the area of different polarity other than channel parts 26a, 26b adjacent to the electrodes 22, 23 is set as a value of Nt. As a result, a protective diode having p<+>n or n<+>p junction formed between the electric poles 23, 22 and the substrate plate 28 as well as the area 29 is operated as a constant voltage element, thus only the yield voltage of these junctions may be applied to the gate Si oxidation film of MOSFET 24a, and 24b.
