Patent ID: 7060616

Claim:
A method of manufacturing a semiconductor device, comprising: forming a gate on a predetermined area of a semiconductor substrate, forming spacers on side walls thereof, and then forming a junction area in a predetermined area of the semiconductor substrate; forming a cobalt film and a buffer layer on the whole structure; forming a cobalt mono-silicide film on the gate and the junction area, by performing a first RTP process; making a surface of the cobalt mono-silicide film amorphous to form an amorphous cobalt silicide film, by performing a carbon ion implanting process; and forming a cobalt di-silicide film, by removing the non-reacting cobalt film and the buffer layer and then performing a second RTP process, wherein the cobalt film is formed to have a thickness of 70 Å to 150 Å, by keeping a reacting furnace, which initially maintains a pressure of 1×10 −7 to 1×10 −8 Torr, in 1×10 −2 to 1×10 −4 Torr and at from a room temperature to a temperature of 550° C., and by using any one of a DC sputtering method, an RF sputtering method and a CVD method.
