    Abstract: A mask frame support unit includes a case, a protruding body extending below the case, and a station having a flat head disposed above the case. The protruding body includes a tapered region and a cylindrical region. The tapered region includes a first end having a first diameter coupled to the case and comprising a second end having a second diameter opposite the first end. The second diameter is less than the first diameter, and the tapered region is coupled to the cylindrical region at the second end. The case houses a number of components including an upper receiving plate in contact with the station, a lower receiving plate disposed underneath the upper receiving plate, a flat head unit movement support mechanism disposed between the lower receiving plate and the body, and a centering component.

    Abstract: The present disclosure relates to a corner spoiler designed to decrease high deposition rates on corner regions of substrates by changing the gas flow. In one embodiment, a corner spoiler for a processing chamber includes an L-shaped body fabricated from a dielectric material, wherein the L-shaped body is configured to change plasma distribution at a corner of a substrate in the processing chamber. The L-shaped body includes a first and second leg, wherein the first and second legs meet at an inside corner of the L-shaped body. The length of the first or second leg is twice the distance defined between the first or second leg and the inside corner. In another embodiment, a shadow frame for a depositing chamber includes a rectangular shaped body having a rectangular opening therethrough, and one or more corner spoilers coupled to the rectangular shaped body at corners of the rectangular shaped body.

    Abstract: Implementations described herein generally relate to components and methods used in plasma processing, and more specifically relate to grooved surfaces for controlling RF return path lengths in plasma processing chambers and methods for forming the same. In one implementation, a backing plate for a plasma processing chamber is provided. The backing plate comprises a rectangular body. The rectangular body has a front surface, a back surface opposing the front surface, a first axis perpendicular to a center of the rectangular body and a plurality of grooves formed in the front surface. At least one groove of the plurality of grooves has a first length across the groove in a first location and a second length across the groove in a second location.
