    Abstract: Embodiments described herein relate to apparatus for performing electron beam reactive plasma etching (EBRPE). In one embodiment, an apparatus for performing EBRPE processes includes an electrode formed from a material having a high secondary electron emission coefficient. In another embodiment, an electrode is movably disposed within a process volume of a process chamber and capable of being positioned at a non-parallel angle relative to a pedestal opposing the electrode. In another embodiment, a pedestal is movably disposed with a process volume of a process chamber and capable of being positioned at a non-parallel angle relative to an electrode opposing the pedestal. Electrons emitted from the electrode are accelerated toward a substrate disposed on the pedestal to induce etching 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.

    Abstract: In one implementation, a showerhead assembly is provided. The showerhead assembly comprises a first electrode having a plurality of openings therethrough and a gas distribution faceplate attached to a first lower major surface of the electrode. The gas distribution plate includes a plurality of through-holes for delivering process gases to a processing chamber. The gas distribution plate is divided into a plurality of temperature-control regions. The showerhead assembly further comprises a chill plate positioned above the electrode for providing temperature control and a plurality of heat control devices to manage heat transfer within the showerhead assembly. The heat control device comprises a thermoelectric module and a heat pipe assembly coupled with the thermoelectric module. Each of the plurality of heat control devices is associated with a temperature control region and provides independent temperature control to its associated temperature control region.
