Patent ID: 7215028

Claim:
A semiconductor device comprising: a semiconductor substrate; a first insulating film provided over the semiconductor substrate; an interconnect layer provided in at least an upper portion of the first insulating film; a second insulating film provided on the first insulating film and the interconnect layer; a third insulating film provided on the second insulating film; and at least one conductor contact portion passing through the third insulating film and the second insulating film to reach the interconnect layer, wherein the interconnect layer consists of a conductor surface film and a metal interconnect film, an upper portion of the interconnect layer is provided with a recess so that an upper surface of the metal interconnect film is located lower than a topmost portion of the conductor surface film to form a level gap between the metal interconnect film and the conductor surface film, and a portion of the second insulating film located on the interconnect layer has a greater thickness than a portion thereof located on the first insulating film.
