    摘要: Apparatus and methods for distributing gas in a semiconductor process chamber are provided. In an embodiment, a gas distributor for use in a gas processing chamber comprises a body. The body includes a baffle with a gas deflection surface to divert the flow of a gas from a first direction to a second direction. The gas deflection surface comprises a concave surface. The concave surface comprises at least about 75% of the surface area of the gas deflection surface. The concave surface substantially deflects the gas toward a chamber wall and provides decreased metal atom contamination from the baffle so that season times can be reduced.

    摘要: A remote plasma process for removing unwanted deposition build-up from one or more interior surfaces of a substrate processing chamber after processing a substrate disposed in the substrate processing chamber. In one embodiment, the substrate is transferred out of the substrate processing chamber and a flow of a fluorine-containing etchant gas is introduced into a remote plasma source where reactive species are formed. A continuous flow of the reactive species from the remote plasmas source to the substrate processing chamber is generated while a cycle of high and low pressure clean steps is repeated. During the high pressure clean step, reactive species are flown into the substrate processing chamber while pressure within the substrate processing chamber is maintained between 4-15 Torr. During the low pressure clean step, reactive species are flown into the substrate processing chamber while reducing the pressure of the substrate processing chamber by at least 50 percent of a high pressure reached in the high pressure clean step.

    摘要: According to a disclosed embodiment, a flow indication counter is incremented each time a data packet is transmitted from a buffer. When the number of data packets transmitted equals or exceeds a threshold number, a flow indication message comprising the buffer window size is generated and transmitted to the base station controller. Further, flow indication messages can be generated and transmitted every threshold time interval, independently of the number of data packets transmitted to ensure that flow indication messages are sent at least every preset time interval. Moreover, a system for flow control can be constructed comprising a flow indication counter module configured to provide an updated number of data packets transmitted. The system further comprises a window size monitoring module which determines the buffer window size and a message generating module which generates a flow indication message comprising the buffer window size.
