Substrate retaining apparatus, system including the apparatus, and method of using same

A substrate retaining apparatus comprising:

• a baseplate;
• at least one sidewall coupled to the baseplate, wherein the at least one sidewall comprises at least one cooling fluid conduit, configured to allow a liquid cooling fluid to flow there through, and at least one gas conduit;
• at least one pad coupled to and projecting from a sidewall of the at least one sidewall, the at least one pad configured to receive a substrate;
• and
• at least one heat shield coupled to at least one of the at least one sidewall, wherein the at least one heat shield comprises a reflective material on a top surface of the at least one shield, wherein the at least one heat shield comprises an emissive material on a bottom surface of the at least one heat shield, and the at least one heat shield comprises at least one opening on the bottom surface of the at least one heat shield, the at least one opening is fluidly coupled to the at least one gas conduit in the at least one sidewall, wherein the at least one opening is formed within the at least one heat shield.
