Patent ID: 7829978

Claim:
A semiconductor device comprising: a substrate with a recess formed in a source/drain region of said substrate; at least one gate structure on said substrate, the gate structure comprising a gate electrode; at least one “L-like” shaped layer having a first leg immediately adjacent to the gate electrode and extending to a first end along the gate electrode, and a second leg extending to a second end along said substrate, said at least one “L-like” shaped layer being formed of a single, metal-containing first material; at least one spacer in contact with said first and second legs of said at least one “L-like” shaped layer; and an intrinsically stressed layer covering said at least one gate structure, said at least one “L-like” shaped layer, said at least one spacer, and selected areas of said substrate, said intrinsically stressed layer in contact with said first and second ends of said “L-like” shaped layer, the intrinsically stressed layer being formed of the single, metal-containing first material.
