Claim:
1. A system for providing a thermal uniformity during a lithographic process, the system comprising: a source of lithographic energy; a workpiece support having a plurality of thermal devices embedded therein, wherein the workpiece support is configured to support a workpiece concurrent to an exposure of the workpiece to the lithographic energy, wherein the workpiece has a lithography film formed thereover, and wherein the plurality of thermal devices comprise one or more Peltier devices configured to cool the workpiece at a respective predetermined location associated with each of the plurality of thermal devices; and a controller, wherein the controller is configured to individually control 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 wherein the specified temperature distribution comprises a temperature of the lithographic film.
