Patent ID: 8350332

Claim:
A semiconductor device comprising: a first gate electrode formed on a first active region in a semiconductor substrate, and having a first metal-containing conductive film; a second gate electrode formed on a second active region in the semiconductor substrate, and having a second metal-containing conductive film; and an isolation region formed in the semiconductor substrate to segment the first active region and the second active region, wherein a third metal-containing conductive film, which is a part of each of the first gate electrode and the second gate electrode, is continuously formed from a top of the first metal-containing conductive film through a portion above the isolation region to a top of the second metal-containing conductive film, the third metal-containing conductive film is made of a silicide, and is formed by fully siliciding a silicon film in a thickness direction, the third metal-containing conductive film has a thickness greater than those of the first metal-containing conductive film and the second metal-containing conductive film, and the silicon film remains at an end of the first metal-containing conductive film between the first metal-containing conductive film and the third metal-containing conductive film.
