Abstract
A method for fabricating a fully silicided gate, including forming a gate dielectric layer on a semiconductor substrate, depositing an amorphous silicon layer on the gate dielectric layer, forming a metallic layer on the amorphous silicon layer, depositing a hard mask on the metallic layer, wherein the amorphous silicon layer and the metal layer are silicided due to a thermal budget applied thereto, thereby forming a metal silicide layer, and patterning the metal silicide layer based on the hard mask to form a gate.
