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.
