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