摘要:
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.

A method of forming a sidewall spacer on a gate electrode is described. The method includes generating a first plasma from a silicon containing precursor and oxide precursor, and forming a silicon oxy-nitride layer on the sidewall of the gate electrode. The method also includes generating a second plasma from the silicon containing precursor and a nitrogen precursor, and forming a nitride layer on the silicon oxy-nitride layer. The silicon containing precursor can flow continuously between the generation of the first and the second plasmas. Also, a method of forming a sidewall spacer on the side of a gate electrode on a substrate. The method includes forming an oxy-nitride layer on the sidewall, and forming a nitride layer on the oxy-nitride layer, where the substrate wafer is not exposed to air between the formation of the layers.
摘要:
A method and apparatus for cleaning a processing chamber are provided. The cleaning method includes the use of a remote plasma source to generate reactive species and an in situ RF power to generate or regenerate reactive species. The reactive species are generated from a carbon and fluorine-containing gas and an oxygen source.
