Patent ID: 6997197

Claim:
A surface cleaning apparatus comprising: a chamber for holding a semiconductor structure therein; and a thermal transfer device connected to the chamber, the thermal transfer device having a frame with a surface disposed inside the chamber for contacting the semiconductor structure and controlling a temperature of the semiconductor structure in contact with the surface, and having a thermal control module connected to the surface, the thermal control module heating and cooling the surface for cycling the surface temperature; wherein, the thermal control module effects a substantially immediate temperature response of the surface when cycling the surface temperature, the surface cleaning apparatus further comprising a thermal regulator connected to the thermal transfer device for maintaining the thermal transfer device at a predetermined temperature when the surface temperature is being cycled; wherein the thermal regulator provides a heat sink for the thermal transfer device when the thermal control module is cooling the surface of the thermal transfer device, and wherein the thermal regulator provides a heat source when the thermal control module is heating the surface of the thermal transfer device.
