Abstract
A method of depositing metal silicide onto a semiconductor substrate includes a step of depositing, by a CVD process, a first metal silicide layer with silane gas onto the semiconductor substrate. The method also includes a step of thermally treating and chemically cleaning the semiconductor substrate. The method further includes a step of depositing, by the CVD process, a second metal silicide layer with silane gas onto the semiconductor substrate. By this method, cracks in the metal silicide formed on the semiconductor substrate are minimized.
