    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.

    Abstract: Apparatuses including a height-adjustable edge ring, and methods for use thereof are described herein. In one example, a process kit for processing a substrate is provided. The process kit has a support ring comprising an upper surface having an inner edge disposed at a first height and an outward edge disposed at a second height less than the first height, the inner edge having a greater thickness than the outward edge. An edge ring is disposed on the support ring, an inner surface of the edge ring interfaced with the inner edge of the support ring. A cover ring is disposed outward of the edge ring, the edge ring independently moveable relative to the support ring and the cover ring. Push pins are disposed inward of the cover ring, the push pins operable to elevate the edge ring while constraining radial movement of the support ring.
