APPARATUS HAVING IMPROVED SUBSTRATE TEMPERATURE UNIFORMITY USING DIRECT HEATING METHODS

摘要

Embodiments of the present invention generally relate to an apparatus and methods for uniformly heating substrates in a processing chamber. In one embodiment, an apparatus generally includes a substrate supporting structure that is able to help minimize the temperature variation across each of the substrates during thermal processing. In one configuration, a substrate supporting structure is adapted to selectively support a substrate carrier to control the heat lost from regions of each of the substrates disposed on the substrate carrier. The substrate supporting structure is thus configured to provide a uniform temperature profile across each of the plurality of substrates during processing.
