Patent ID: 7786538

Claim:
A semiconductor device comprising: a silicon substrate including a first semiconductor region of a first conductivity type; and a first MOSFET comprising: first source and drain regions of a second conductivity type formed at a distance from each other in the first semiconductor region; a first insulating film formed on a portion of the first semiconductor region, the portion being located between the first source region and the first drain region; a first gate electrode formed on the first insulating film; a first sidewall insulating film formed at side portions of the first gate electrode; a first single-crystal silicon layer formed on each of the first source and drain regions, and having at least an upper-face made of a {111} plane; a first NiSi layer formed at least on the first single-crystal silicon layer, and having a portion whose interface with the first single-crystal silicon layer is on the {111} plane of the first single-crystal silicon layer and a part of the portion of the first NiSi layer being in contact with the first sidewall insulating film; and a first TiN film being in contact with the portion of the first NiSi layer on the {111} plane of the first single-crystal silicon layer.
