    摘要: Apparatus and methods for distributing gases into a processing chamber are disclosed. In one embodiment, the method for processing a substrate includes delivering a processing gas into a chemical vapor deposition chamber through a first gas pathway that includes flow through a first plurality of apertures in a blocker plate, the blocker plate creating a pressure drop of at least approximately 0.8 torr thereacross, reacting the processing gas to deposit a material on a substrate surface, removing the substrate from the chamber, delivering a cleaning gas into the chamber through a second gas pathway around the blocker plate bypassing the blocker plate and through a second plurality of apertures formed in the blocker plate, and reacting the cleaning gases with deposits within the chamber to etch the deposits from the chamber.

    摘要: Apparatus and methods for distributing gases into a processing chamber are disclosed. In one embodiment, the apparatus includes a gas distribution plate having a plurality of apertures disposed therethrough and a blocker plate having both a plurality of apertures disposed therethrough and a plurality of feed through passageways disposed therein. A first gas pathway delivers a first gas through the plurality of apertures in the blocker plate with sufficient pressure drop to more evenly distribute the gases prior to passing through the gas distribution plate. A bypass gas pathway delivers a second gas through the plurality of feed through passageways in the blocker plate and to areas around the blocker plate prior to the second gas passing through the gas distribution plate.
