A process for manufacturing a semiconductor device includes: forming first contact holes in a dielectric film for a PMOS transistor; depositing germanium on the source/drain regions of the PMOS transistor exposed from the first contact holes; heat treating the germanium with silicon in the source/drain regions of the PMOS transistor to form a germanium silicide film; forming second contact holes in the dielectric film for the source/drain regions of the NMOS transistor; and forming contact plugs in the first and second contact holes.
