    摘要: Methods and apparatus for controlling power distribution in a substrate processing system are provided. In some embodiments, a substrate processing system including a process chamber having a substrate support and a processing region disposed above the substrate support; a first conduit disposed above the processing region to provide a portion of a first toroidal path that extends through the first conduit and across the processing region; a second conduit disposed above the processing region to provide a portion of a second toroidal path that extends through the second conduit and across the processing region; an RF generator coupled to the first and second conduits to provide RF energy having a first frequency to each of the first and second conduits; an impedance matching network disposed between the RF generator and the first and second conduits; and a power divider to control the amount of RF energy provided to the first and second conduits from the RF generator.
