Abstract

A process of manufacturing a semiconductor device having a dual gate CMOS transistor in which an nMOS transistor in the dual gate CMOS transistor is formed by the steps of: (a) forming a gate insulating film and a silicon film on a semiconductor substrate; (b) implanting n-type impurities into the silicon film in an nMOS region of the semiconductor substrate; (c) forming a conductive film on the silicon film; and (d) patterning the silicon film and the conductive film into a gate electrode.
