  • Publication number: 20140007413
    Abstract: A method for manufacturing a plasma processing system is provided. The method includes providing a movable plasma-facing structure configured to surround a plasma that is generated during processing of a substrate. The method also includes disposing a movable electrically conductive structure outside of the movable plasma-facing structure, wherein both structures configured to be deployed and retracted as a single unit to facilitate handling of the substrate. The movable electrically conductive structure is radio frequency (RF) grounded during the plasma processing. During processing, the RF current from the plasmas flows to the movable electrically conductive structure through the movable plasma-facing structure during the plasma processing. The method further includes coupling a set of conductive straps to the movable electrically conductive structure.

  • Patent number: 8590813
    Abstract: A rotary atomizer applies particulate paints with good color matching by reducing paint droplet size deviation and then optimizing the other paint spraying parameters. Paint droplet size parameters are reduced by using a bell cup having reduced flow deviations, including an overflow surface having a generally constant angle between a deflector and an atomizing edge.

  • Publication number: 20130292056
    Abstract: An edge ring assembly surrounds a substrate support surface in a plasma etching chamber. The edge ring assembly comprises an edge ring and a dielectric spacer ring. The dielectric spacer ring, which surrounds the substrate support surface and which is surrounded by the edge ring in the radial direction, is configured to insulate the edge ring from the baseplate. Incorporation of the edge ring assembly around the substrate support surface can decrease the buildup of polymer at the underside and along the edge of a substrate and increase plasma etching uniformity of the substrate.

  • Patent number: 8573153
    Abstract: An improved upper electrode system has a multi-part electrode in which a central portion of the electrode having high wear is replaceable independent of an outer peripheral portion of the electrode. The upper electrode can be used in plasma processing systems for processing semiconductor substrates, such as by etching or CVD. The multi-part upper electrode system is particularly useful for large size wafer processing chambers, such as 300 mm wafer processing chambers for which monolithic electrodes are unavailable or costly.

  • Publication number: 20130256266
    Abstract: Methods and apparatuses for controlling plasma generation in a plasma processing chamber to reduce an effective residence time of by-product gases or to control in real time the concentration of certain polymer pre-cursors or reaction by-products in the plasma processing chamber are disclosed. The gas residence time is “effectively” reduced by reducing the plasma reaction for at least a portion of the process time. Thresholds can be provided to control when the plasma reaction is permitted to proceed at the full rate and when the plasma reaction is permitted to proceed at the reduced rate. By reducing the rate of plasma by-product generation at least for a portion of the process time, the by-product gas residence time may be effectively reduced to improve process results.
