发明名称 Chemically active slurry for the polishing of noble metals and method for same
摘要 A slurry and CMP process to polish a noble metal surface is provided. The slurry and polishing process are used to form a damascene, or dual damascene noble metal inlay. Such as inlay is useful is forming an integrated circuit ferroelectric capacitor electrode. The slurry includes a halogen, such as bromine, in a basic aqueous solution to chemically react with the noble metal. With an abrasive added, the slurry is used to polish and remove noble metals from a wafer surface during a CMP process.
