Abstract:
A method of forming a refractory metal silicide component comprising:forming a refractory metal layer over a substrate, the refractory metal layer having an exposed surface;forming a silicon-containing structure over a portion of the exposed surface of the refractory metal layer, the silicon-containing structure having an outer surface, the outer surface having a surface portion proximate the refractory metal layer;forming a silicon diffusion restricting layer over at least some of the proximate surface portion and a silicon diffusion restricting region within the refractory metal layer; andafter forming the silicon diffusion restricting layer and the silicon diffusion restricting region, annealing the substrate to cause a silicide forming reaction between at least some of the refractory metal layer and at least some of the silicon-containing structure.
