  • Patent number: 11972971
    Abstract: A wafer lift pin system is capable of dynamically modulating or adjusting the flow of gas into and out of lift pins of the wafer lift pin system to achieve and maintain a consistent pressure in supply lines that supply the gas to the lift pins. This enables the wafer lift pin system to precisely control the speed, acceleration, and deceleration of the lift pins to achieve consistent and repeatable lift pin rise times and fall times. A controller and various sensors and valves may control the gas pressures in the wafer lift pin system based on various factors, such as historic rise times, historic fall times, and/or the condition of the lift pins. This enables smoother and more controlled automatic operation of the lift pins, which reduces and/or minimizes wafer shifting and wafer instability, which may reduce processing defects and maintain or improve processing yields.

  • Patent number: 11875973
    Abstract: Methods for preparing a void-free protective coating are disclosed herein. The void-free protective coating is used on a dielectric window having a central hole, which is used in a plasma treatment tool. A first protective coating layer is applied to the window, leaving an uncoated annular retreat area around the central hole. The first protective coating layer is polished to produce a flat surface and fill in any voids on the window. A second protective coating layer is then applied upon the flat surface of the first protective coating layer to obtain the void-free coating. This increases process uptime and service lifetime of the dielectric window and the plasma treatment tool.
