Abstract:
A process for fabricating a semiconductor structure, comprising:providing a semiconductor substrate having an insulting film formed thereon;forming a polysilicon layer on said insulating film;forming a barrier layer over said polysilicon layer and a metal silicide layer comprising a TiSi.sub.x M.sub.y compound alloy formed on top of said barrier layer, wherein M of said TiSi.sub.x M.sub.y compound alloy is a metal selected from the group consisting of tantalum (Ta), niobium (Nb), and molybdenum (Mo);depositing an anti-reflection film on top of said metal silicide layer;implanting a dopant into said metal silicide layer by passing through said anti-reflection film; andforming a capping layer over said anti reflection film.
