Patent ID: 6991740

Claim:
A method for polishing at least one wafer using a chemical-mechanical planarization apparatus, the chemical-mechanical planarization apparatus having a polishing pad having an attachment surface for attaching the polishing pad to a portion of the chemical-mechanical planarization apparatus and having a polishing surface for planarizing a surface of the at least one wafer using a chemical-mechanical planarization process by movement of the polishing pad with respect to the at least one wafer, comprising: providing a platen having a first surface for adhesive attachment of the attachment surface of the polishing pad thereto, the first surface having at least one channel therein, the 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; providing a carrier for holding the at least one wafer against the polishing surface of the polishing pad; providing an apparatus for moving the platen and carrier relative to each other for the chemical-mechanical planarization process of at least a portion of the surface of the at least one wafer; and contacting the at least one wafer with the polishing pad attached to the platen during a chemical-mechanical planarization process.
