摘要：
A semiconductor device includes a semiconductor substrate containing a p-type diffusion layer and an n-type diffusion layer which are separated by an element separation film; a gate insulating film formed on or above the p-type diffusion layer and the n-type diffusion layer of the semiconductor substrate, respectively; a gate electrode containing a metallic film and formed on the gate insulating film; a Ge inclusion formed at an interface between the gate insulating film and the metallic film; and a silicon-containing layer formed on the metallic film.
