Abstract:
A thermal processing system for thermally processing a substrate, the thermal processing system comprising:a process chamber; a substrate holder whereon the substrate resides within the process chamber; a heater assembly disposed within the process chamber, wherein the heater assembly is operable to heat the substrate; a cold plate disposed within the process chamber, wherein the cold plate is operable to substantially cool the substrate, the cold plate comprising a plurality of radially-moveable segments; a radial translation device operably coupled to the plurality of segments, wherein the radial translation device is operable to radially translate each of the plurality of segments between an engaged position and a disengaged position; and an elevator operably coupled to the substrate holder, wherein the elevator is operable to vertically translate the substrate residing on the substrate holder between a heating position proximate to the heater assembly and a cooling position proximate to the cold plate, and wherein the plurality of segments are in the disengaged position when the substrate is in the heating position, and wherein the plurality of segments are in the engaged position when the substrate is in the cooling position.
