Patent ID: 7560318

Claim:
A process of forming an electronic device comprising: providing a workpiece, wherein: the workpiece includes a first semiconductor layer, an insulating layer, and a base layer; the insulating layer lies between the first semiconductor layer and the base layer, and the first semiconductor layer has a first stress, the first stress having a first magnitude and a first type; forming a second semiconductor layer over the first semiconductor layer, wherein the second semiconductor layer has a second stress, the second stress having a second magnitude and a second type; annealing the workpiece such that the second semiconductor layer has a third stress, the third stress having a third magnitude and a third type, wherein the third magnitude is different than the second magnitude; and removing at least a portion of the second semiconductor layer to expose a portion of the first semiconductor layer, wherein after removing the at least a portion of the second semiconductor layer, the first semiconductor layer has a fourth stress, the fourth stress having a fourth magnitude and a fourth type, and the fourth type is opposite the second type.
