Patent ID: RE42004

Claim:
A method of fabricating a semiconductor device, comprising: the first step of defining an element active region by forming an element isolation structure on a semiconductor substrate; the second step of forming an insulating film on said semiconductor substrate in said element active region; the third step of forming a first conductive film on an entire surface of said semiconductor substrate including said insulating film, and said element isolation structure; the fourth step of forming a mask pattern having first and second openings on said first conductive film; the fifth step etching said first conductive film until said element isolation structure is exposed in said first opening by using said mask pattern as a mask, thereby dividing said first conductive film, and simultaneously forming a recess in said second opening where said first conductive film forms a bottom of said recess; the sixth step of forming a dielectric film so as to cover a surface of said firs conductive film; and the seventh step of forming a second conductive film on said dielectric film opposing said first conductive film through said dielectric film.
