    摘要: Embodiments of the present invention provide electrostatic chucks for operating at elevated temperatures. One embodiment of the present invention provides a dielectric chuck body for an electrostatic chuck. The dielectric chuck body includes a substrate supporting plate having a top surface for receiving a substrate and a back surface opposing the top surface, an electrode embedded in the substrate supporting plate, and a shaft having a first end attached to the back surface of the substrate supporting plate and a second end opposing the first end. The second end is configured to contact a cooling base and provide temperature control to the substrate supporting plate. The shaft is hollow having a sidewall enclosing a central opening, and two or more channels formed through the sidewall and extending from the first end to the second end.

    摘要: A method of creating a plasma-resistant thermal oxide coating on a surface of an article, where the article is comprised of a metal or metal alloy which is typically selected from the group consisting of yttrium, neodymium, samarium, terbium, dysprosium, erbium, ytterbium, scandium, hafnium, niobium or combinations thereof. The oxide coating is formed using a time-temperature profile which includes an initial rapid heating rage, followed by a gradual decrease in heating rate, to produce an oxide coating structure which is columnar in nature. The grain size of the crystals which make up the oxide coating 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 the oxide coating is in compression at the interface between the oxide coating and the metal or metal alloy substrate.

    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.
