Abstract

A method of forming a multi-layer silicide gate structure for a MOS type semiconductor device that includes the processing steps of first providing a substrate, then depositing a gate oxide layer on the substrate, then depositing a first refractory metal silicide layer which has a first stoichometry on the gate oxide layer, and finally depositing a second refractory metal silicide layer which has a second stoichometry different than the first stoichometry on the first deposited refractory metal silicide layer.
