    Abstract: Embodiments of the disclosure include a method of processing a substrate in a plasma processing system, comprising delivering an RF signal, by an RF generator, through an RF match to an electrode assembly disposed within the plasma processing system, wherein while delivering the RF signal the RF match is set to a first matching point, and delivering a voltage waveform, by a waveform generator, to the electrode assembly disposed within the plasma processing system while the RF signal is delivered to the electrode assembly. The method includes receiving, by the RF match, a synchronization signal from a RF generator or the waveform generator, measuring, by an output sensor of the RF match, a first set of impedance related data of the plasma processing system over a first time period, the first time period beginning after a first delay triggered by a first portion of a first waveform pulse of the synchronization signal, measuring, by the output sensor of the RF match, a second set of impedance related data of the plasma processing system over a second time period, the second time period beginning after a second delay triggered by the first portion of the first waveform pulse of the synchronization signal, calculating, by the RF match, a combined impedance parameter based on the measured first set of impedance related data and the measured second set of impedance related data, and adjusting a matching parameter within the RF match based on the calculated combined impedance parameter to achieve a second matching point.

    Abstract: Embodiments of the present disclosure generally include an apparatus and methods for measuring and controlling in real-time a potential formed on a substrate in a plasma processing chamber during plasma processing. Embodiments of the disclosure include a plasma processing system that includes a substrate support disposed within a processing volume of the plasma processing system, the substrate support comprising a substrate supporting surface and a dielectric layer disposed between a first electrode and the substrate supporting surface. The plasma processing system further includes a first generator coupled to a second electrode of the plasma processing system, and a sensor disposed a first distance from the substrate supporting surface. The first generator is configured to generate a plasma within the processing volume. The first electrode is disposed a second distance from the substrate supporting surface, and the first distance is less than the second distance. The sensor is generally configured to detect an electric field strength and/or a voltage formed on the substrate during plasma processing.

    Abstract: Methods for forming a high current inductor leverage solid core materials to form ribbon inductors. In some embodiments, the method may include forming a central opening lengthwise through a solid core conductive material, wherein the solid core conductive material has an outer diameter, the central opening forms an inner diameter of the solid core conductive material, and a difference between the outer diameter and the inner diameter is a thickness of a ribbon conductor of the high current inductor and removing a spiral portion of the solid core conductive material to form the ribbon conductor of the high current inductor, wherein a width of the spiral portion forms a gap spacing between windings of the ribbon conductor.

    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.
