摘要：
A method of forming a semiconductor device comprising: forming a gate dielectric layer over a channel region; forming a gate electrode on the gate dielectric layer; forming source/drain regions substantially aligned with respective edges of the gate electrode with the channel region therebetween; forming a thin metal layer on the source/drain regions; forming a metal alloy layer on the thin metal layer; and transforming the thin metal layer into a low resistance metal silicide.
