    摘要: Methods and apparatus for reducing particles in a gas delivery system are provided herein. In some embodiments, a method of fabricating a gas distribution apparatus, such as a gas distribution plate or nozzle, for a semiconductor process chamber includes providing a gas distribution apparatus having one or more apertures adapted to flow a gas therethrough. A slurry is flowed through the one or more apertures to remove a damaged surface from sidewalls of the plurality of apertures. In some embodiments, the gas distribution apparatus may be oxidized before or after flowing the slurry through the one or more apertures. In some embodiments, the gas distribution apparatus may be conditioned by providing RF power to the gas distribution plate for a desired period of time.

    摘要: An article which is resistant to corrosion or erosion by chemically active plasmas and a method of making the article are described. The article is comprised of a metal or metal alloy substrate having on its surface a coating which is an oxide of the metal or metal alloy. The structure of the oxide coating is columnar in nature. The grain size of the crystals which make up the oxide is larger at the surface of the oxide coating than at the interface between the oxide coating and the metal or metal alloy substrate, and wherein the oxide coating is in compression at the interface between the oxide coating and the metal or metal alloy substrate. Typically the metal is selected from the group consisting of yttrium, neodymium, samarium, terbium, dysprosium, erbium, ytterbium, scandium, hafnium, niobium or combinations thereof.

    摘要: A cleaning process for recovering an anodized aluminum part is particularly useful when the part has been exposed to a fluorine-containing plasma in etch reactor. The part is bathed in an agitated solution of a fluoride acid, such as ammonium fluoride, which converts aluminum fluoride to a soluble fluoride. The part is rinsed in water. The pores of the cleaned anodization may be resealed by a submerging the part in hot agitated deionized water.

    摘要: A diamond coating formed on a bulk member used in a plasma processing chamber for processing a substrate such as a semiconductor wafer. The coating is particularly useful in a plasma etching chamber using a chlorine-based chemistry to etch metal. One class of such parts includes a dielectric chamber wall, in particular, a chamber wall through which RF or microwave energy is coupled into the chamber to support the plasma. For example, an RF inductive coil is positioned outside the chamber wall and inductively couples energy into the chamber. Exemplary substrates for the diamond coating include alumina, silicon nitride, silicon carbide, polysilicon, and a SiC/Si composite. Amorphous carbon may be substituted for diamond.
