Abstract

An insulated gate semiconductor device contains a protective element for protecting the gate electrode of an insulated gate field effect transistor. The protective element is formed of the same semiconductor layer as that of the gate electrode of the insulated gate field effect transistor and is formed integrally with the gate electrode on an insulating film formed on the surface of a semiconductor substrate.
