Abstract
A system and method for processing substrates that achieves isothermal and uniform fluid flow processing conditions for a plurality of substrates. In one aspect, the invention is a system and method that utilizes matching the emissivity value of the surfaces of a process chamber that oppose exposed surfaces of the substrates with the emissivity value of the exposed surfaces to achieve isothermal conditions throughout a substrate stack. In another aspect, the invention is system and method of processing substrates in a process chamber that exhibits excellent fluid flow uniformity by eliminating cavities or geometrical irregularities in the process chamber profile due to substrate loading openings. In yet anther aspect, the invention is a system and method of processing substrates wherein the process chamber comprises a liner and a shell, the liner constructed of a highly thermally conductive material, such as carbon, and the shell is constructed of a non-porous material, such as stainless steel.
