Abstract
A method of forming wirings which includes forming a film of a silicon-containing metal layer at a high temperature on an underlying metal, thereby forming a silicon alloy layer which includes the underlying metal and the silicon-containing metal during film formation. In a case of forming wirings by a silicon-containing metal layer, occurrence of Si nodules can be eliminated to obtain wirings of high reliability.
