Abstract:
A method of manufacturing a semiconductor device, the method comprising:providing a silicon-containing semiconductor substrate, having an upper surface, comprising: a gate electrode formed on the substrate upper surface with a gate insulating layer therebetween, the gate electrode having an upper surface and opposing side surfaces; amorphizing selected regions of the semiconductor substrate; forming source/drain regions by doping the selected regions of the semiconductor substrate with a dopant; depositing a metal layer over the semiconductor substrate; and annealing the semiconductor substrate, wherein said metal layer is exposed, with a single heating step at a temperature of about 350Â° C. to less than about 850Â° C. for about 30 seconds to 60 minutes, to simultaneously activate the source/drain regions and to react the metal layer with underlying silicon in the gate electrode and source/drain regions to form metal silicide contacts.
