Abstract:
A method of introducing strain in a channel region of a FinFET device includes forming a fin structure on a substrate, the fin structure having a lower portion comprising a sacrificial layer and an upper portion comprising a strained semiconductor layer; and removing a portion of the sacrificial layer corresponding to a channel region of the FinFET device so as to release the upper portion of the fin structure from the substrate in the channel region.

Claim (Index 11):
A method of forming a semiconductor device structure, the method comprising:\n patterning a hardmask layer to block an NFET region of a silicon-on-insulator (SOI) substrate; recessing an SOI layer in a PFET region of the SOI substrate; doping the recessed layer in the PFET region to form a sacrificial layer having an etch selectivity with respect to the SOI layer; forming a compressively strained silicon germanium (SiGe) layer over the sacrificial layer; removing the hardmask layer and forming one or more fins in the NFET region and one or more fins in the PFET region, wherein NFET fins comprise the SOI layer, and wherein PFET fins have a lower portion comprising the sacrificial layer and an upper portion comprising the compressively strained SiGe layer; and removing a portion of the sacrificial layer corresponding to a channel region of the one or more PFET fins so as to release the upper portion from the SOI substrate in the channel region; wherein the NFET fins comprise a diffusion barrier.
