Abstract
Stable suicides are formed utilizing excimer laser crystallization in place of a conventional second high temperature rapid thermal processing annealing step. Specifically, thermally unstable silicide having a metal-rich surface layer is conventionally formed utilizing deposition of refractory metal followed by low temperature annealing. After removal of unreacted refractory metal, an amorphous silicon film is deposited on top of the unstable silicide and exposed to radiation from an excimer laser, such that the amorphous silicon melts, reacts with refractory metal from the underlying unstable silicide, and reforms as thermally stable silicide evidencing low electrical resistance.
