Abstract:
A polishing apparatus used for the chemical-mechanical-planarization of at least one wafer, said polishing apparatus having a polishing pad having an attachment surface for attaching said polishing pad to a portion of said polishing apparatus and having a polishing surface for planarizing a surface of said wafer using said chemical-mechanical-planarization process by the movement of said polishing pad with respect to said wafer, comprising:a platen having a first surface for adhesive attachment of the attachment surface of the polishing pad thereto, said platen including a coating of a fluoropolymer material on at least a portion of the first surface thereof for the adhesive attachment of the polishing pad thereto; a carrier for holding a wafer against said polishing surface of said polishing pad; and apparatus for moving said platen and substrate carrier relative to each other for said mechanical-chemical-planarization process of at least a portion of the surface of a wafer.
