  • Patent number: 10763338
    Abstract: The present disclosure describes a silicide formation process which employs the formation of an amorphous layer in the SiGe S/D region via an application of a substrate bias voltage during a metal deposition process. For example, the method includes a substrate with a gate structure disposed thereon and a source/drain region adjacent to the gate structure. A dielectric is formed over the gate structure and the source-drain region. A contact opening is formed in the dielectric to expose a portion of the gate structure and a portion of the source/drain region. An amorphous layer is formed in the exposed portion of the source/drain region with a thickness and a composition which is based on an adjustable bias voltage applied to the substrate. Further, an anneal is performed to form a silicide on the source/drain region.
