Abstract:
1. A method for refurbishing at least a portion of an electrostatic chuck having a plate and a first dielectric component, wherein the first dielectric component comprises a tube inserted into the plate and the plate is adapted to be positioned within a channel to define a plenum, wherein the first dielectric component provides at least a portion of a fluid passage coupled to the plenum and a porous dielectric layer formed upon the dielectric component covers an opening of the tube and provides at least another portion of the fluid passage that extends axially above the opening, the method comprising: removing the porous dielectric layer and the first dielectric component from the plate of the electrostatic chuck, wherein the first dielectric component is positioned to provide a fluid to a back surface of a substrate that faces the electrostatic chuck when the substrate is disposed on the electrostatic chuck; replacing the first dielectric component with a second dielectric component to provide at least a portion of the fluid passage; and forming a second porous dielectric layer upon the second dielectric component to cover the opening of the tube and provide at least another portion of the fluid passage that extends axially above the opening.
