  • Abstract
    This paper provides a brief introduction of CMP evolution for Cu damascene interconnects including its technology, performance drivers, and unique set of challenges. A manufacturing worthy Cu CMP solution calls attention to all key attributes involved. Discussions and examples are centered around corrosion control, role of abrasive in maintaining chemical and mechanical balance, scratch reduction and overall Cu/barrier process integration.
