    摘要: Method and apparatus for uniform direct radiant heating in a rapid thermal processing reactor where uniformity of temperature across the width and breadth of a semiconductor wafer is achieved by placement of a dome-shaped thermal insert in close proximity to a semiconductor wafer in process. Thermal energy is absorbed by the thermal insert from the semiconductor wafer at a high rate where the spacing between the thermal insert and semiconductor wafer is at a minimum and at a gradually reduced rate where the spacing between the thermal insert and semiconductor wafer is gradually increased. A guard ring is also incorporated to negate bottom side reflective thermal energy exposure.

    摘要: 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.
