Filed: 1980-09-02
Abstract: PURPOSE:To obtain an input protecting device strong against a large current by using an insulated gate type FET in which the second gate electrode is disposed via an insulating film on the first gate electrode as a gate protection. CONSTITUTION:A polycrystalline silicon resistor 2 is formed between an input terminal 3 and a terminal 4 consecutive to an input terminal 3, and a floating electrode 9 of a protecting transistor TR is simultaneously formed.
