  • Publication number: 20230271298
    Abstract: A chemical mechanical planarization (CMP) tool includes a platen and a polishing pad attached to the platen, where a first surface of the polishing pad facing away from the platen includes a first polishing zone and a second polishing zone, where the first polishing zone is a circular region at a center of the first surface of the polishing pad, and the second polishing zone is an annular region around the first polishing zone, where the first polishing zone and the second polishing zone have different surface properties.
    Type: Application
    Filed: May 5, 2023
