Abstract

A method and apparatus for controlling the temperature of at least one gas flowing into a processing chamber is provided. In one embodiment, a gas temperature control apparatus for semiconductor processing includes a gas delivery line coupled between a processing chamber and a gas source. An enclosure substantially encloses the gas delivery line and is adapted to flow a heat transfer fluid away from the processing chamber.
