Application: Methods for preparing void-free coatings for plasma treatment components (Patent ID: US20230367339A1)

The patent filed by Taiwan Semiconductor Manufacturing Co Ltd. discloses methods for preparing a void-free protective coating for a dielectric window used in a plasma treatment tool. The protective coating involves applying a first layer, polishing it to create a flat surface, and then adding a second layer to achieve a void-free coating. This innovation aims to enhance the process uptime and service lifetime of the dielectric window and the plasma treatment tool, ultimately improving overall efficiency and performance.

The claims associated with the patent detail the specific components and characteristics of the plasma treatment tool, such as the materials used for the dielectric window, the protective coating composition, and the dimensions of the uncoated annular retreat area. Additionally, the method for plasma treating a semiconducting wafer substrate using the described protective coating is outlined, emphasizing the importance of the void-free coating's thickness, surface roughness, hardness, and crystallinity. By incorporating a two-layer protective coating system, the patent introduces a novel approach to ensuring the durability and effectiveness of the dielectric window in plasma treatment applications, potentially setting a new standard for the industry.
