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 18):
A strained FinFET structure, comprising:\n a lower fin material formed on a substrate, the lower fin material disposed at opposing ends of a channel region; an upper fin material formed on the lower fin material, the upper fin material comprising a strained semiconductor material, and wherein the lower fin material comprises a material that is etch selective with respect to the upper fin material; and wherein the channel region below the upper portion comprises a removed section of the lower fin material such that the upper fin material in the channel region is released from the substrate, thereby resulting in strain introduced throughout an entire height of the upper fin material in the channel region; wherein the lower fin material comprises n-doped silicon.
