Abstract: A method of forming a transparent carbon layer on a substrate is provided. The method comprises generating an electron beam plasma above a surface of a substrate positioned over a first electrode and disposed in a processing chamber having a second electrode positioned above the first electrode. The method further comprises flowing a hydrocarbon-containing gas mixture into the processing chamber, wherein the second electrode has a surface containing a secondary electrode emission material selected from a silicon-containing material and a carbon-containing material. The method further comprises applying a first RF power to at least one of the first electrode and the second electrode and forming a transparent carbon layer on the surface of the substrate.

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.
