Abstract:
1. A semiconductor structure comprising: a substrate comprising a bulk layer, an insulator layer and a device layer; a first heating element formed within the bulk layer, wherein a first side of the first heating element is adjacent to a first portion of the insulator layer, and wherein the first heating element is adjusted to he selectively activated to generate thermal energy to heat said first portion of the insulator layer and anneal a trapped electrical charge from said first portion of the insulator layer; a thermal insulating layer formed within the bulk layer and adjacent to a second side of said first heating element, wherein the thermal insulating layer comprises a thermal conductivity that is less than a thermal conductivity of said bulk layer, and wherein the thermal insulating layer is adapted to thermally isolate the second side of the first heating element from the bulk layer; and a thermal isolation structure formed surrounding a third side, a fourth side, a fifth side, and a sixth side of said first heating element, wherein the thermal isolation structure thermally isolates the third side, the fourth side, the fifth side, and the sixth side of the first heating element from the bulk layer.
