    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.
