Abstract

PURPOSE:To effectively prevent the damage of a gate in an MISFET by inserting a protective resistor between a gate electrode and a gate input terminal and two diodes connected reversely through the resistor between the gate electrode and a substrate. CONSTITUTION:Diodes 23, 24 are connected reversely through a resistor 20' in a distribution manner between a gate electrode 8 and a substrate electrode 9 (ground). Then, one diode reversely biased constantly is inserted irrespective of the polarity in the surge voltage, thereby preventing the gate damage due to application of surge voltage from the terminal side of a power source. An N type resistance region 20 formed in the P type layer 19 of an N type substrate can form the layer 19 simultaneously upon formation of the P type layer of N channel FET, the impurity density of the layers 19 and 20 are selected with respect to the N type substrate to set the breakdown voltage of the diodes 23, 24. With this construction, the structure is simple and has large protective effect.
