发明名称 Process and composition for electrochemical mechanical polishing
摘要 Compositions and methods for processing a substrate having a conductive material layer disposed thereon are provided. In one embodiment, a composition for processing a substrate having a conductive material layer disposed thereon is provided which composition includes an acid based electrolyte, a chelating agent, a corrosion inhibitor, a passivating polymeric material, a pH adjusting agent, a leveler a solvent, and a pH between about 3 and about 10. The composition is used in a method to form a passivation layer on the conductive material layer, abrading the passivation layer to expose a portion of the conductive material layer, applying a bias to the substrate, and removing the conductive material layer.
