Abstract
A method of ensuring against deterioration of an underlying silicide layer over which a refractory material layer is deposited by physical vapor deposition (PVD) or chemical vapor deposition (CVD) is realized by first providing a continuous polysilicon layer prior to the refractory material deposition. The continuous polysilicon layer, preferably no thicker than 50 Å, serves a sacrificial purpose and prevents interaction between any fluorine that is released during the refractory material deposition step from interacting with the underlying silicide.
