    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: Disclosed herein is a method for applying plasma-resistant coatings for use in semiconductor processing apparatus. The coatings are applied over a substrate which typically comprises an aluminum alloy of the 2000 series or the 5000 through 7000 series. The coating typically comprises an oxide or a fluoride of Y, Sc, La, Ce, Eu, Dy, or the like, or yttrium-aluminum-garnet (YAG). The coating may further comprise about 20 volume % or less of Al2O3. The coatings are typically applied to a surface of an aluminum alloy substrate or an anodized aluminum alloy substrate using a technique selected from the group consisting of thermal/flame spraying, plasma spraying, sputtering, and chemical vapor deposition (CVD). To provide the desired corrosion resistance, it is necessary to place the coating in compression. This is accomplished by controlling deposition conditions during application of the coating.

    摘要: Disclosed herein is a gas distribution plate for use in a gas distribution assembly for a processing chamber, where the gas distribution plate is fabricated from a solid yttrium oxide-comprising substrate, which may also include aluminum oxide. The gas distribution plate includes a plurality of through-holes, which are typically crescent-shaped. Through-holes which have been formed in the solid yttrium oxide-comprising substrate by ultrasonic drilling perform particularly well. The solid yttrium oxide-comprising substrate typically comprises at least 99.9% yttrium oxide, and has a density of at least 4.92 g/cm3, a water absorbency of about 0.02% or less, and an average grain size within the range of about 10 μm to about 25 μm. Also disclosed herein are methods for fabricating and cleaning the yttrium oxide-comprising gas distribution plate.

    摘要: An electrostatic chuck has an electrode embedded in a dielectric which is mounted on a pedestal. The dielectric has a contact surface with an average surface roughness of less than about 0.5 μm, a surface peak waviness of less than about 0.12 μm, and a surface peak waviness material ratio of greater than about 20%. The surface texture can be formed by lapping the dielectric surface with a slurry of abrasive particles.

    摘要: Particulate generation has been a problem in semiconductor device processing in highly corrosive plasma environments. The problem is exacerbated when the plasma is a reducing plasma. Empirically produced data has shown that the formation of a plasma spray coated yttrium-comprising ceramic such as yttrium oxide, Y2O3—ZrO2 solid solution, YAG, and YF3 provides a low porosity coating with smooth and compacted surfaces when such ceramics are spray coated from a powder feed having an average effective diameter ranging from about 22 μm to about 0.1 μm. These spray-coated materials reduce the generation of particulates in corrosive reducing plasma environments.
