Classification: CPC H  G | IPC H

Claim 0:
1. A structure, comprising:
a substrate;
a semiconductor device disposed on the substrate, wherein the semiconductor device comprises a first doped region, an intermediate region located within an area surrounded by the first doped region, and a second doped region located within an area surrounded by the first doped region and the intermediate region, and the first doped region and the second doped region have opposite conductivity types;
a heating structure surrounding the semiconductor device, wherein the heating structure comprises:
an intrinsic semiconductor area, wherein the semiconductor device is located within an area surrounded by the intrinsic semiconductor area, and the intrinsic semiconductor area is physically separated from the intermediate region by the first doped region;
at least one heating element located at a periphery of the intrinsic semiconductor area; and
at least one heating pad joined with the at least one heating element, wherein the at least one heating pad comprises a plurality of contact structures, and the contact structures are arranged to receive a voltage to control a temperature of the at least on heating element.
