    摘要： A substrate processing system that includes a ceramic substrate holder having an RF electrode embedded within the substrate holder and a gas inlet manifold spaced apart from the substrate holder. The gas inlet manifold supplies one or more process gases through multiple conical holes to a reaction zone of a substrate processing chamber within the processing system and also acts as a second RF electrode. Each conical hole has an outlet that opens into the reaction zone and an inlet spaced apart from the outlet that is smaller in diameter than said outlet. A mixed frequency RF power supply is connected to the substrate processing system with a high frequency RF power source connected to the gas inlet manifold electrode and a low frequency RF power source connected to the substrate holder electrode. An RF filter and matching network decouples the high frequency waveform from the low frequency waveform. Such a configuration allows for an enlarged process regime and provides for deposition of films, including silicon nitride films, having physical characteristics that were previously unattainable.

    摘要： An apparatus and methods for an upgraded CVD system that provides a plasma for efficiently cleaning a chamber, according to a specific embodiment. Etching or depositing a layer onto a substrate also may be achieved using the upgraded CVD system of the present invention. In a specific embodiment, the present invention provides an easily removable, conveniently handled, and relatively inexpensive microwave plasma source as a retrofit for or a removable addition to existing CVD apparatus. In a preferred embodiment, the remote microwave plasma source efficiently provides a plasma without need for liquid-cooling the plasma applicator tube. In another embodiment, the present invention provides an improved CVD apparatus or retrofit of existing CVD apparatus capable of producing a plasma with the ability to efficiently clean the chamber when needed.
