Abstract:
A method of forming a field effect transistor (FET) device includes forming a patterned gate structure over a substrate; forming a solid source dopant material on the substrate, adjacent sidewall spacers of the gate structure; performing an anneal process at a temperature sufficient to cause dopants from the solid source dopant material to diffuse within the substrate beneath the gate structure and form source/drain extension regions; following formation of the source/drain extension regions, forming trenches in the substrate adjacent the sidewall spacers, corresponding to source/drain regions; and forming an embedded semiconductor material in the trenches so as to provide a stress on a channel region of the substrate defined beneath the gate structure.
