On a substrate, a gate insulating film, a polysilicon film on the gate insulating film, and a resist pattern on the polysilicon film are formed. Subsequently an exposed portion of the polysilicon film which is not covered with the resist pattern is removed. The surface of the polysilicon film left after the step of removing the exposed portion of the polysilicon film is thermally oxidized to form a gate electrode and an insulating film simultaneously on the surface of the gate electrode.
