Abstract:
An apparatus for controlling a temperature of a microelectronic substrate, the substrate having a first surface and a second surface opposite the first surface, the apparatus comprising: a substrate support having at least one support surface for engaging and supporting the substrate, the support surface being rotatable about an axis extending through the substrate and perpendicular to the first surface and the second surface; and a temperature controller positioned at least proximate to the substrate support, the temperature controller having a first thermal link coupled with a first portion of the substrate and a second thermal link coupled with a second portion of the substrate, the first and second thermal links being separately controllable for transferring heat to or from the first and second portions of at least one of the first and second surfaces at different rates, wherein the first thermal link comprises a first nozzle configured to direct a first fluid stream toward the first portion of the substrate, and the second thermal link comprises a second nozzle configured to direct a second fluid stream toward the second portion of the substrate.
