  • Methods and apparatus for plasma processing
    Patent number: 6696662
    Abstract: Plasma processing is carried out at pressures of about atmospheric pressure, at pressures below atmospheric pressure, or at pressures above atmospheric pressure. The plasmas are generated using a RF power source and a rectangular waveguide. The plasmas can be used for applications such as materials processing and carrying out chemical reactions.

  • RF power process apparatus and methods
    Publication number: 20020170677
    Abstract: Described are methods and apparatus for coupling RF power. In one embodiment, the method includes the step of flowing an RF current through an RF induction coil having a sufficiently large surface area and a low profile that results in effective RF power coupling to the load. Preferably, the turns of the coil comprise sheets of metal and the coil turns are substantially parallel to each other. Another aspect of the present invention is an apparatus for carrying out processes that use RF power.
