Abstract:
A system and method is provided for providing a thermal distribution on a workpiece during a lithographic process. The system provides a source of lithographic energy to workpiece, such as a workpiece having a lithographic film formed thereover. A workpiece support having a plurality of thermal devices embedded therein is configured to support the workpiece concurrent to an exposure of the workpiece to the lithographic energy. A controller individually controls a temperature of each of the plurality of thermal devices, therein controlling a specified temperature distribution across the workpiece associated with the exposure of the workpiece to the lithographic energy. Controlling the temperature of the thermal devices can be based on a model, a measured temperature of the workpiece, and/or a prediction of a temperature at one or more locations on the workpiece.

Claim (Index 20):
A method for providing a thermal uniformity during a lithographic process, the method comprising:\n positioning a substrate, which has a layer formed over a face of the substrate, on a substrate support, wherein the substrate support includes a plurality of thermal devices embedded therein; exposing the substrate to a source of lithographic energy; and heating or cooling each of the plurality of thermal devices concurrent with the exposure of the substrate to the source of lithographic energy, wherein the plurality of thermal devices are configured to heat or cool the substrate at a respective predetermined location, therein controlling a specified temperature distribution across the substrate, wherein the specified temperature distribution comprises a temperature of the layer.
