Abstract: In a method for manufacturing a semiconductor device, a dielectric layer is formed on a substrate, and a contact hole is formed from the dielectric layer to the substrate. A dielectric spacer liner is formed to cover a sidewall and a bottom of the contact hole. A portion of the dielectric spacer liner is removed to expose a portion of the substrate. A metal silicide layer is formed into the substrate through the contact hole.
