The surface of a silicon substrate is sputter-etched so that silicon clusters sputtered out form a silicon film on a side wall spacer. Then, a metal film of cobalt, titanium or the like is built up on the entire surface. Thereafter, silicidizing process is carried out to form metal silicide layers on a diffusion layer and the side wall spacer. Then, an inter-layer insulation film 14 is formed and is photo-etched to provide the inter-layer insulation film with a contact hole 15 overlapping the side wall spacer.
