Patent ID: 8038796

Claim:
An apparatus for control of a temperature of a substrate comprising: a temperature-controlled base having a top surface, said base configured to receive cooling media to control a temperature of said base; a plate having a heater film thermally coupled to a bottom surface of the plate, the plate having a thickness adequate to transfer a spatial pattern of the heater film to the substrate, the plate having a bottom surface, the top and bottom surfaces being substantially parallel to each other and having a variation in surface flatness within about 0.0005 inch; a first layer of adhesive, wherein the first layer of adhesive is configured to bond said plate and said heater film to the top surface of said temperature-controlled base, said first layer of adhesive having a variation in thickness within 0.001 inch; and a layer of dielectric material bonded to a top surface of said plate, the layer of dielectric material configured to form an electrostatic clamping mechanism for supporting the substrate.
