摘要:
Electrostatic chucks and methods of manufacturing the same are provided herein. In some embodiments, an electrostatic chuck comprises an electrically conductive body having one or more channels formed in an upper surface thereof; a plate positioned within the one or more channels to define one or more plenums between the body and the plate, wherein the surfaces of the plenum are anodized; one or more fluid passages disposed in the plate and fluidly coupling the one or more plenums to the upper surface of the body, wherein the surfaces of the fluid passages are electrically insulated; and a dielectric layer disposed over the upper surface of the body and the plate, wherein the dielectric layer forms a support surface for a substrate to be disposed thereon.
