    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.
