Abstract:
A reactor for coating particles includes a vacuum chamber configured to hold particles to be coated, a vacuum port to exhaust gas from the vacuum chamber via the outlet of the vacuum chamber, a chemical delivery system configured to flow a process gas into the particles via a gas inlet on the vacuum chamber, one or more vibrational actuators located on a first mounting surface of the vacuum chamber, and a controller configured to cause the one or more vibrational actuators to generate a vibrational motion in the vacuum chamber sufficient to induce a vibrational motion in the particles held within the vacuum chamber.
Abstract:
A dilution stage is adapted to supply a dilute chemistry to a semiconductor device processing apparatus. The dilution stage includes a first vessel adapted to store the chemistry after dilution and a second vessel adapted to store the chemistry prior to dilution. The dilution stage may also include a control mechanism which is adapted to selectively control flowing of the chemistry and a dilutant to the first vessel. The control mechanism may be operative to fill the second vessel with the chemistry, and to flow the dilutant to the first vessel via the second vessel.
Abstract:
The present invention provides systems, methods and apparatus for processing of semiconductor wafers. Specifically, embodiments of the present invention include apparatus designed to resist etching and deposition by processing and cleaning gases in a processing chamber. The apparatus of the present invention allow multiple process steps to be performed in situ in the same chamber to reduce total processing time and facilitate cleaning of the processing chamber. In one embodiment of the invention, a heating assembly for heating a semiconductor wafer within a deposition apparatus comprises a pedestal having a substantially planar upper surface for supporting the semiconductor wafer thereon and a heating element disposed therein for heating the wafer to the required temperatures for processing. According to the invention, the pedestal includes a protective layer substantially covering and adhered to the wafer support surface. The material used in the layer is substantially resistant to reactions with and deposition by process gases and cleaning gases at temperatures up to 500.degree. C. The thickness of the protective layer usually ranges from about 2 to 30 mils and preferably between about 5 to 10 mils.
Abstract:
The present invention provides systems, methods and apparatus for high temperature (at least about 500-800° C.) processing of semiconductor wafers. The systems, methods and apparatus of the present invention allow multiple process steps to be performed in situ in the same chamber to reduce total processing time and to ensure high quality processing for high aspect ratio devices. Performing multiple process steps in the same chamber also increases the control of the process parameters and reduces device damage. In particular, the present invention can provide high temperature deposition, heating and efficient cleaning for forming dielectric films having thickness uniformity, good gap fill capability, high density, low moisture, and other desired characteristics.
Abstract:
An apparatus for fabricating an integrated circuit device comprises an enclosure housing a processing chamber and having a gas inlet for receiving process gases into the processing chamber and a gas outlet for discharging the process gases. A pedestal is disposed within the processing chamber for supporting a wafer thereon. A chamber liner at least partially surrounds the pedestal and includes inner and outer portions. The inner portion comprises a material that is substantially resistant to the process gases at temperatures of at least about 400° C. The outer portion comprises an insulating material for decreasing a thermal gradient between the perimeter of the wafer and the enclosure.
