Claim:
1. A semiconductor structure comprising: a silicon structure suspended above a topmost surface of an insulator layer; a functional gate structure positioned around said silicon structure suspended above said topmost surface of said insulator layer; a source side non-suspended silicon structure located on one side of said functional gate structure and positioned on a surface of an oxidized silicon germanium alloy material, wherein outermost vertical sidewalls of said source side non-suspended silicon structure are vertically coincident to outermost vertical sidewalls of said oxidized silicon germanium alloy material; and a drain side non-suspended silicon structure located on another side of said functional gate structure and positioned on a surface of another oxidized silicon germanium alloy material, wherein outermost vertical sidewalls of said drain-side non-suspended silicon structure are vertically coincident to outermost vertical sidewalls of said another oxidized silicon germanium alloy material, and wherein said oxidized silicon germanium alloy material and said another oxidized silicon germanium alloy material introduce a strain into a channel portion of said silicon structure suspended above said topmost surface of said insulator layer.
