Abstract:
Embodiments of the disclosure provide a plasma source assembly and process chamber design that can be used for any number of substrate processing techniques. The plasma source may include a plurality of discrete electrodes that are integrated with a reference electrode and a gas feed structure to generate a uniform, stable and repeatable plasma during processing. The plurality of discrete electrodes include an array of electrodes that can be biased separately, in groups or all in unison, relative to a reference electrode. The plurality of discrete electrodes may include a plurality of conductive rods that are positioned to generate a plasma within a processing region of a process chamber. The plurality of discrete electrodes is provided RF power from standing or traveling waves imposed on a power distribution element to which the electrodes are connected.

Claim (Index 14):
A plasma source assembly, comprising:\n a power distribution element connected to an array of discrete electrodes, wherein the array of discrete electrodes are arranged in a pattern that is distributed in at least two non-parallel directions that are both substantially parallel to a first plane; a first RF generator having an input that receives a first RF control signal and an output that provides RF power to a first connection point on the power distribution element; a second RF generator having an input that receives a second RF control signal and an output that provides RF power to a second connection point on the power distribution element; a phase shifter that provides the first RF control signal to the input of the first RF generator in response to a phase shift control signal and a second RF control signal; a signal generator that provides the second RF control signal to the phase shifter and to the input of the second RF generator; a phase detector that is configured to detect a difference in the phase of the output from the first RF generator and the output from the second RF generator; and a phase controller that receives the detected phase difference from the phase detector and provides the phase shift control signal to the phase shifter to alter the phase of the first RF signal.
