Zusammenfassung:A novel pad-in-a-bottle (PIB) technology for advanced chemical-mechanical planarization (CMP) copper barrier CMP compositions, systems and processes has been disclosed for use with polyurethane-based polishing pads having a plurality of asperities. The CMP composition comprises abrasives, polyurethane beads, and surfactant. The polishing pad lifetime increasing is achieved using PIB-type Cu barrier CMP polishing composition.
