  • Patent number: 7800226
    Abstract: A method for forming a metal silicide region in a silicon region of a semiconductor substrate. The method comprises forming a metal layer over the silicon region, then in succession forming a titanium and a titanium nitride layer thereover. As the substrate is heated to form the silicide, the titanium getters silicon dioxide on the surface of the silicon region and the titanium nitride promotes the formation of a smooth surface at the interface between the silicide layer and the underlying silicon region.
    Type: Grant
    Filed: June 22, 2007
    Date of Patent: September 21, 2010
    Assignee: Agere Systems Inc.
