Abstract:
A workpiece holder includes a puck, first and second heating devices in thermal communication with respective inner and outer portions of the puck, and a thermal sink in thermal communication with the puck. The first and second heating devices are independently controllable, and the first and second heating devices are in greater thermal communication with the puck, than thermal communication of the thermal sink with the puck. A method of controlling temperature distribution of a workpiece includes flowing a heat exchange fluid through a thermal sink to establish a reference temperature to a puck, raising temperatures of radially inner and outer portions of the puck to first and second temperatures greater than the reference temperature, by activating respective first and second heating devices disposed in thermal communication with the radially inner and outer portions of the puck, and placing the workpiece on the puck.

Claim (Index 20):
The semiconductor processing system of  claim 19 , wherein the workpiece holder further comprises a thermal sink that extends substantially beneath the bottom surface of the puck, the thermal sink comprising a metal plate that flows a heat exchange fluid through channels defined therein, to maintain a reference temperature for the puck, and wherein the thermal sink mechanically and thermally couples with the puck at a plurality of attachment points that provide a degree of thermal communication between the thermal sink and the puck that is less than a degree of thermal communication between each of the first and second heating devices and the puck.
