Abstract:
A method comprises providing a semiconductor alloy layer on a semiconductor substrate, forming a gate structure on the semiconductor alloy layer, forming source and drain regions in the semiconductor substrate on both sides of the gate structure, removing at least a portion of the semiconductor alloy layer overlying the source and drain regions, and forming a metal silicide region over the source and drain regions.

Claim (Index 16):
A semiconductor device comprising:\n a gate structure formed over a silicon substrate, wherein the gate structure has insulator spacer abutting a sidewall of the gate structure; source and drain regions disposed on either side of the gate structure; a first portion of a semiconductor alloy layer below at least one of the gate structure and the insulator spacer, the first portion of the semiconductor alloy layer being formed of silicon germanium; and a second portion of the semiconductor alloy layer in the source and drain regions, the second portion of the semiconductor alloy layer being formed of silicon germanium and physically contacting the silicon of the substrate, wherein the second portion the semiconductor alloy layer includes a silicide of silicon germanium.
