Abstract

A highly conductive layer utilizing a layer of Pt in conjunction with sputter deposited or co-evaporated WSi.sub.2 to enhance the conductivity increase of the WSi.sub.2 layer occuring during annealing. The Pt layer is deposited as a thin layer directly on top or beneath the WSi.sub.2 layer or may be incorporated within the WSi.sub.2 layer. During annealing platinum atoms diffuse into the WSi.sub.2 film resulting in lower resistivity values than in comparably deposited annealed film wherein the Pt layer has been omitted.
