Abstract:
A method of manufacturing a semiconductor integrated circuit device, comprising steps of:providing a semiconductor substrate with a gate insulating film of a MISFET formed on a main surface of said semiconductor substrate, a gate electrode of said MISFET formed on said gate insulating film, and a first insulating film covering said gate electrode and side surfaces of said gate electrode, wherein said gate electrode includes refractory metal, and wherein portions of said main surface are exposed through said first insulating film;selectively depositing a silicon film on the exposed portions of said main surface of said semiconductor substrate;forming a refractory metal film on said main surface to cover said silicon film and said first insulating film;annealing said semiconductor substrate to form a silicide film by reacting said refractory metal film and said silicon film; andafter said annealing step, removing unreacted refractory metal film.
