    摘要: A ceramic substrate support and methods for fabricating the same are provided. In one embodiment, a ceramic substrate support for supporting a substrate includes a ceramic body and a porous member disposed therein. The ceramic body generally has an upper portion and a lower portion. The upper portion includes a support surface while the lower portion includes a bottom surface. At least one passage is disposed in the lower portion of the ceramic body. A first end of the passage is at least partially closed by the upper portion of the ceramic body. At least one outlet is disposed through the portion of the ceramic body through the upper portion of the ceramic body and fluidly couples the passage to the support surface.

    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.
