Abstract:
A single substrate thermal processing chamber, comprising:a first wall having at least a portion thereof which allows transmission of radiant heat into the chamber, the first wall having a substantially planar inner surface and an outer surface that is at least partially concavely curved over at least a portion of the wall that allows transmission of radiant heat into the chamber; a second wall; a side wall connected to the first and second walls to define an interior cavity surrounded by the first wall, the second wall and the side wall, wherein the first wall forms a separation between the inside of the interior cavity and the outside of the interior cavity to prevent process gases from passing therethrough, the side wall having at least one inlet port and one outlet port, wherein the substantially planar inner surface of the first wall spans substantially the entire distance between the inlet port and the outlet port; and a support structure positioned within the interior cavity of the processing chamber.
