摘要:
A method for cleaning a plasma enhanced chemical vapor deposition chamber. The method includes introducing a cleaning gas into the plasma enhanced chemical vapor deposition chamber, forming a plasma using a very high frequency (VHF) power having a frequency in a range from about 20 MHz to about 100 MHz, and reacting the cleaning gas with deposits within the chamber in the presence of the plasma.

The present invention is a method and apparatus for cleaning a chemical vapor deposition (CVD) chamber using cleaning gas energized to a plasma in a gas mixing volume separated by an electrode from a reaction volume of the chamber. In one embodiment, a source of RF power is coupled to a lid of the chamber, while a switch is used to couple a showerhead to ground terminals or the source of RF power.

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.

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.

The invention provides a method and apparatus to control fluids such as process gases into two or more substrate process chambers. In one aspect, the gas flow from a first supply to a first processing region is used to control the gas flow of a second supply to a second processing region where the total gas flow is about equal to the total of the gas flows into both the first and second processing regions. In another aspect, the gas flow rate from the first supply for the first processing region is about equal to the gas flow rate for the second supply to the second processing region.
