Abstract: A showerhead for a processing chamber in a substrate processing system includes an upper portion having a lower surface and an upper surface and a faceplate. A lower surface of the faceplate is below the lower surface of the upper portion such that the showerhead extends into an interior volume of the processing chamber and the faceplate includes a plurality of holes arranged in a pattern to provide fluid communication between a remote plasma source above the showerhead and the interior volume of the processing chamber. A sidewall extends upward from an outer edge of the faceplate between the faceplate and the upper portion and the upper portion extends radially outward from the sidewall of the showerhead and is configured to be mounted on a sidewall of the processing chamber. A heater is embedded in the upper portion of the showerhead.

Abstract: A side tuning ring for a gas distribution device of a substrate processing system includes a first ring adjacent to a faceplate of the gas distribution device. The first ring surrounds the faceplate and defines a first plenum, communicates with a first gas source, and includes a first plurality of holes arranged to direct gas from the first gas source into a process chamber at a first angle. A second ring is adjacent to the first ring. The second ring surrounds the first ring and defines a second plenum, communicates with at least one of the first gas source and a second gas source, and includes a second plurality of holes arranged to direct gas from the at least one of the first gas source and the second gas source into the process chamber at the first angle or a second angle. The first ring and the second ring are detachable from the faceplate of the gas distribution device.

Abstract: A vaporization device includes a cartridge having a reservoir that holds a vaporizable material, a heating element, and a wicking element that can draw the vaporizable material to the heating element to be vaporized. The wicking element can include two ends in contact with the reservoir. The cartridge can include an airflow control feature for controlling airflow in the cartridge.

Abstract: A method for operating a substrate processing chamber includes after performing a process using a fluorine-based gas in the substrate processing chamber: a) during a first predetermined period, supplying a gas mixture to the substrate processing chamber including one or more gases selected from a group consisting of molecular oxygen, molecular nitrogen, nitric oxide and nitrous oxide and supplying RF power to strike plasma in the substrate processing chamber; b) during a second predetermined period after the first predetermined period, supplying molecular hydrogen gas and RF power to the substrate processing chamber; c) repeating a) and b) one or more times; d) purging the substrate processing chamber with molecular nitrogen gas; e) increasing chamber pressure; f) evacuating the substrate processing chamber; and g) repeating d), e) and f) one or more times.

Abstract: Three fixed reference stations having known positions comprise Omega receivers. Phase measurements made at all three stations are assembled at a master station, utilizing landlines or radio links and, using the known positions of the stations, a central processing unit calculates not merely the offset of the master station as measured from the true position but also the errors in the azimuths of the propagation directions of the received signals. The position measurement of a vehicle with an Omega receiver is corrected on the basis of the offset and also the errors in the said azimuths. Sufficient accuracy is achieved for finding the position of land based vehicles whose position may be calculated subject to the corrections in the master station on the basis of raw data transmitted to the master station over a link. Alternatively the azimuth corrections may be transmitted to the vehicle over the link. Two fixed stations suffice if they can measure absolute phase.

Abstract: Separate electrical timing and load activation devices are provided for each of plural electrical loads and each device is connected to receive reference timing signals from a central unit. Each of the separate timing and load activation devices measures a reference time interval accurately defined by the reference timing signals and subsequently activates its associated electrical load after a respectively corresponding predetermined time delay which is determined as a function of the locally measured reference time interval.

Abstract: An electrically ignited load such as a fusehead is connected to the secondary winding of a transformer. The secondary winding is magnetically linked to a primary winding through a magnetic circuit and the transformer is constructed so as to provide a substantial leakage inductance associated with the secondary winding and effectively connected in series with the load to be ignited. The structure selectively passes electrical ignition energy to the load only in response to input electrical energy having predetermined magnitude and frequency characteristics.
