摘要: Aqueous polishing slurries for chemical-mechanical polishing are effective for polishing copper at high polish rates. The aqueous slurries according to the present invention may include soluble salts of molybdenum dissolved in an oxidizing agent and molybdic acid dissolved in an oxidizing agent. Methods for polishing copper by chemical-mechanical planarization include polishing copper with low pressures using a polishing pad and a aqueous slurries including soluble salts of molybdenum dissolved in an oxidizing agent and molybdic acid dissolved in an oxidizing agent, particles of MoO3 dissolved in an oxidizing agent, and particles of MoO2 dissolved in an oxidizing agent.

摘要: Method for polishing copper by chemical-mechanical planarization. The method of the present invention includes dissolving MoO3 in an oxidizing agent and deionized water to form a first slurry; filtering the first slurry; adding supplemental ceramic/metal oxide nano-particles to the first slurry after filtering, forming an aqueous slurry; introducing the aqueous slurry between the copper and a polishing pad; and, polishing the copper by moving the polishing pad and the copper relative to one another.
