    摘要: A method and apparatus for providing a fluid distribution element for an electrostatic chuck that reduces plasma formation and arcing within heat transfer fluid passages. One embodiment comprises a plate and a dielectric component, where the dielectric component is inserted into the plate. The plate is adapted to be positioned within a channel to define a plenum, wherein the dielectric component provides at least a portion of a fluid passage coupled to the plenum. A porous dielectric layer, formed upon the dielectric component, provides at least another portion of a fluid passage coupled to the plenum. In other embodiments, the fluid distribution element comprises various arrangements of components to define a fluid passage that does not provide a line-of-sight path from the support surface for a substrate to a plenum.

    摘要: A method of making an electrostatic chuck comprising positioning a plate into a channel in a body to form a plenum and inserting a dielectric component into an opening in the plate, where the dielectric component defines a portion of a passage from the plenum. Thereafter, depositing a dielectric layer covering at least a portion of the body and at least a portion of the plate to form a support surface. The dielectric layer is polished to a specified thickness. In one embodiment, the polishing process forms an opening through the dielectric layer to enable the dielectric component to define a passage between the support surface and the plenum. In another embodiment, at least a portion of the dielectric layer is porous proximate the dielectric component such that the porous dielectric layer and the dielectric component form a passage between the support surface and the plenum. In a further embodiment, a hole is formed through the dielectric layer and the hole in the dielectric layer and the dielectric component form a passage between the support surface and the plenum.
