Patent ID: 8592270

Claim:
A method of forming complementary metal oxide semiconductor (CMOS) devices, the method comprising: forming a patterned field effect transistor FET gate structure of a first polarity type and a patterned FET gate structure of a second polarity type over a substrate; selectively forming trenches in the substrate adjacent sidewall spacers of the FET gate structure of the first polarity type; forming a solid source dopant material on the substrate, in the trenches adjacent the sidewall spacers of the FET gate structure of the first polarity type, and adjacent sidewall spacers of the FET gate structure of the second polarity type; performing an anneal process at a temperature sufficient to cause dopants from the solid source dopant material to diffuse within the substrate beneath the FET gate structure of the second polarity type and FET gate structure of the first polarity type, respectively, so as to form source/drain extension regions beneath the FET gate structure of the second polarity type and halo regions beneath the FET gate structure of the first polarity type; removing remaining portions of the solid source dopant material not diffused beneath the FET gate structure of the second polarity type and FET gate structure of the first polarity type; forming additional trenches in the substrate adjacent the sidewall spacers of the FET gate structures, corresponding to source/drain regions; forming a first embedded semiconductor material in the additional trenches adjacent the sidewall spacers of the FET gate structure of the first polarity type so as to provide a first type of stress on a channel region of the substrate defined beneath the FET gate structure of the first polarity type; and forming a second embedded semiconductor material in the additional trenches adjacent the sidewall spacers of the FET gate structure of the second polarity type so as to provide a second type of stress on a channel region of the substrate defined beneath the FET gate structure of the second polarity type.
