    摘要: Compositions and methods for processing a substrate having a conductive material layer disposed thereon are provided. In one embodiment, a method of electrochemically processing a substrate using a conductive polishing article is provided. The method includes disposing a substrate having a conductive material layer formed thereon in a process apparatus comprising a cathode coupled to the conductive polishing article and an anode, wherein the substrate is in electrical contact with the anode, supplying a polishing composition comprising a cathodic inhibitor and an anodic inhibitor, forming a protective film on the cathode to prevent corrosion of the cathode, and polishing the substrate. In another embodiment, a composition for processing a substrate having a conductive material layer disposed thereon is provided which composition includes a corrosion inhibitor selected from the group of an amino acid based inhibitor, a polymeric based corrosion inhibitor, an oxidizer, a chelating inhibitor or combinations thereof.

    摘要: A method and apparatus for removing conductive material from a substrate surface are provided. In one embodiment, a method is provided for electrochemical mechanical polishing of a substrate. A substrate comprising dielectric feature definitions, a barrier material disposed on the feature definitions, and a bulk conductive material in an amount sufficient to fill the feature definitions is provided. The substrate is exposed to an electrolyte solution. A passivation layer is formed on the conductive material. The passivation strength of the passivation layer is increased by polishing the substrate with a first voltage for a first time period. The substrate is polished with a second voltage higher than the first voltage for a second time period. Conductive material is removed from at least a portion of the substrate surface by anodic dissolution.

    摘要: An ECMP method that suppresses hillock formation on a substrate includes the step of buffing a substrate before a two-step electrochemical mechanical polishing process. The buffing step prevents hillocks from forming around the features of the substrate and does not interfere with the protrusion formation. The buffing step includes contacting the substrate with a polishing pad and rotating the substrate and the polishing pad in opposite directions.

    摘要: Embodiments of a conditioning head for in-situ conditioning and/or cleaning a processing pad of a CMP, ECMP, or other processing system are provided. In one embodiment, the conditioning head includes a brush disposed in a central cavity. A cleaning fluid is provided through the central cavity of the conditioning head to a processing pad. The brush spins and moves laterally across the surface of the processing pad. The cleaning solution dispensed through the conditioning head dissolves by-products of the processing operation while the brush gently wipes the processing pad. A lip of the conditioning head retains the cleaning fluid and cleaning waste, thereby minimizing contamination of the area outside of the conditioning head. The cleaning waste is removed from the processing pad via passages formed near the outer periphery of the conditioning head.

    摘要: Polishing compositions and methods for removing conductive materials from a substrate surface are provided. In one aspect, a composition is provided for removing at least a conductive material from a substrate surface including sulfuric acid or derivative, phosphoric acid or derivative, a first chelating agent including an organic salt, a pH adjusting agent to provide a pH between about 2 and about 10 and a solvent. The composition may further include a second chelating agent. The composition may be used in a single step or two step electrochemical mechanical planarization process. The polishing compositions and methods described herein improve the effective removal rate of materials from the substrate surface, such as tungsten, with a reduction in planarization type defects.
