Disclosed are a gas showerhead, a method of manufacturing the same, and a plasma apparatus provided with the gas showerhead. The gas showerhead comprises a back plate and a gas distribution plate, the gas distribution plate including a plurality of annular gas distribution regions with the center of the gas distribution plate as their center; on each annular gas distribution region are provided a plurality of gas through-holes penetrating through the gas inlet face and the gas outlet face, the gas through-holes at least including a plurality of first gas through-holes inclined at a certain angle, and the gas through-holes further include a plurality of second gas through-holes, the second gas through-holes being parallel to the central axis or having a radial inclination direction different from the first gas through-holes; and in the same annular gas distribution region, gas flowing out of the first gas through-holes and gas flowing out of the second gas through-holes are kept away from each other.

An advanced coating for parts used in plasma processing chamber. The advanced coating is formed over an anodized surface that has not been sealed. After the coating is formed, the coated area is masked, and the remaining anodized surface is sealed. The porous and rough structure of the anodized but un-sealed aluminum enhances adhesion of the coating. However, to prevent particle generation, the exposed anodized surface is sealed after formation of the coating. The coating can be of yttria, formed by plasma enhanced atomic deposition techniques which results in a dense and smooth coating.
