  • Publication number: 20040082193
    Abstract: A method of depositing a low dielectric constant film on a substrate. In one embodiment, the method includes the steps of positioning the substrate in a deposition chamber, providing a gas mixture to the deposition chamber, in which the gas mixture is comprised of one or more cyclic organosilicon compounds, one or more aliphatic compounds and one or more oxidizing gases. The method further includes reacting the gas mixture in the presence of an electric field to form the low dielectric constant film on the semiconductor substrate. The electric field is generated using a very high frequency power having a frequency in a range of about 20 MHz to about 100 MHz.

  • Publication number: 20040052969
    Abstract: A method for processing a substrate. The method includes introducing one or more precursors into a chemical vapor deposition chamber through a gas distribution plate heated by a heating mechanism disposed at a bottom plate of the gas distribution plate, reacting the precursors to deposit a material on a substrate surface, removing the substrate from the chamber, introducing a cleaning gas into the chamber through the gas distribution plate, and reacting the cleaning gas with deposits within the chamber until substantially all the deposits are consumed.

  • Publication number: 20040050492
    Abstract: An apparatus for distributing gas in a processing system. In one embodiment, the system includes a gas distribution assembly having a gas distribution plate. The gas distribution plate defines a plurality of holes through which gases are transmitted. The assembly further includes a gas box coupled to the gas distribution plate, in which the gas box is configured to supply the gases into the plurality of holes. The assembly further includes a means for reducing heat transfer from the gas box to the gas distribution plate.
