Patent ID: 7525160

Claim:
A semiconductor device, comprising: a substrate comprising a bulk semiconductor material, the bulk semiconductor material having a first crystal lattice with a first lattice structure and a first lattice spacing; an insulating layer on the bulk semiconductor material; a body region extending from the bulk semiconductor material through the insulating layer, the body region having a top surface and two side walls exposed above the insulating layer, the two side walls being separated by a width and extending for a length; a gate electrode adjacent to at least a portion of the top surface and adjacent to at least a portion of each of the two side walls of the body region, there by forming three gates; a source recess and a drain recess formed in the top surface and formed in both side walls of the body region on either side of the gate electrode; and a stress material in the source and drain recesses, the stress material comprising a second material with a second crystal lattice with a second lattice structure substantially the same as the first lattice structure and a second lattice spacing different than the first lattice spacing.
