发明名称 Self-aligned dual-metal silicide and germanide formation
摘要 A method includes growing an epitaxy semiconductor region at a major surface of a wafer. The epitaxy semiconductor region has an upward facing facet facing upwardly and a downward facing facet facing downwardly. The method further includes forming a first metal silicide layer contacting the upward facing facet, and forming a second metal silicide layer contacting the downward facing facet. The first metal silicide layer and the second metal silicide layer comprise different metals.
