  • Patent number: 11508560
    Abstract: A focus ring adjustment assembly of a system for processing workpieces under vacuum, where the focus ring may include a lower side having a first surface portion and a second surface portion, the first surface portion being vertically above the second surface portion. The adjustment assembly may include a pin configured to selectively contact the first surface portion of the focus ring, and an actuator operable to move the pin along the vertical direction between an extended position and a retracted position. The extended position of the pin may be associated with the distal end of the pin contacting the first surface of the focus ring and the focus ring being accessible for removal by a workpiece handling robot from the vacuum process chamber.

  • Patent number: 11195718
    Abstract: Systems and methods for processing a workpiece are provided. In one example, a method includes placing a workpiece on a workpiece support in a processing chamber. The method includes performing a spacer treatment process to expose the workpiece to species generated from a first process gas in a first plasma to perform a spacer treatment process on a spacer layer on the workpiece. The first plasma can be generated in the processing chamber. After performing the spacer treatment process, the method can include performing a spacer etch process to expose the workpiece to neutral radicals generated from a second process gas in a second plasma to etch at least a portion of the spacer layer on the workpiece. The second plasma can be generated in a plasma chamber that is remote from the processing chamber.

  • Publication number: 20200258718
    Abstract: Plasma processing apparatus and associated methods are provided. In one example implementation, the plasma processing apparatus can include a gas supply in a processing chamber of a plasma processing apparatus, such as an inductively coupled plasma processing apparatus. The gas supply can include one or more injectors. Each of the one or more injectors can be angled relative to a direction parallel to a radius of the workpiece to produce a rotational gas flow relative to a direction perpendicular to a center of the workpiece. Such gas supply can improve process uniformity, workpiece edge critical dimension tuning, gas ionization efficiency, and/or symmetric flow inside the processing chamber to reduce particle deposition on a workpiece and can also reduce heat localization from a stagnate flow.
