Abstract
A platform for supporting a semiconductor substrate during processing in a processing chamber includes a body having a first support surface for supporting the substrate thereon and a second support surface for being supported by a rotatable housing over a heater in the processing chamber. The body comprises a quartz material, with at least a portion of the quartz material being adapted to be opaque to block transmission of photon energy through that portion during heating. For example, the quartz material may include a coating over at least a portion of the quartz material, with the coating adapting the quartz material to be opaque. In preferred form, the coating comprises a composite film of silicon and silicon carbide.
