Abstract: Apparatus for gas distribution in a semiconductor wafer processing chamber 200 having a roof 228. The roof 228 has a top surface 608 and a bottom surface 312. A recess 314 is disposed within the bottom surface 312 of the roof 228. A gas distribution plate 316 is disposed within the recess 314 and a material layer coating 320 is disposed upon the bottom surfaces 312/500 of the roof 228 and the gas distribution plate 316. The material layer coating 320 and the gas distribution plate 316 each have a plurality of apertures 322/404. The apertures 404 of the gas distribution plate 316 coincide with the apertures 322 in the material layer coating 320. The material layer coating 320 is formed from silicon carbide and most preferably is deposited by chemical vapor deposition (CVD). Both the roof 228 and gas distribution plate 316 are fabricated from silicon carbide.

Abstract: A temperature control system 145 is used to control the temperature of a process chamber 25 during processing of a semiconductor substrate 70. The temperature control system 145 comprises a heat exchanger plate 155 for removing heat from the chamber 25, and a heat transfer member 158 for conducting heat to the heat exchanger plate 155. The heat transfer member 158 comprises a lower heat conduction surface 205 bonded to an external surface of the chamber 25, and an upper heat transmitting surface 210 thermally coupled to the heat exchanger plate 155. Preferably, the temperature control assembly comprises a heater 150 for heating the chamber 25, and a computer control system 165 for regulating the heat removed by the heat exchanger plate 155 as well as the heat supplied by the heater 150, to maintain the chamber 25 at substantially uniform temperatures.
