Abstract:
A method of manufacturing a substrate support apparatus for processing a semiconductor wafer, the apparatus including a substrate support, a heat exchange element, and a clamp member, wherein the substrate support includes at least one gas conduit coupled to a corkscrew channel formed on an outer cylindrical surface of the substrate support, the corkscrew channel positioned to transfer gas from a shaft portion of the heat exchanger apparatus to the conduit, and wherein the heat exchanger apparatus further includes a seal member, comprising:(a) mounting the heat exchange element about a portion of the substrate support, wherein the substrate support has a surface for supporting the semiconductor wafer; (b) expanding the seal member; (c) positioning the seal member about the corkscrew channel in the outer cylindrical surface of the substrate support; (d) contracting the seal member about the substrate support to form a corkscrew conduit; (e) expanding the clamp member relative to the substrate support; (f) positioning the clamp member about a portion of the substrate support; and (g) contracting the clamp member into contact with a portion of the substrate support and the heat exchange element to maintain the heat exchange element In contact with the substrate support.
