    摘要: Embodiments described herein provide a method for polishing a substrate surface. The methods generally include storing processing components in multiple storage units during processing, and combining the processing components to create a slurry while flowing the processing components to a polishing pad. A substrate is polished using the slurry, and the thickness of a material layer disposed on the substrate is determined. The flow rate of one or more processing components is then adjusted to affect the rate of removal of the material layer disposed on the substrate.

    摘要: A method and apparatus for pre-conditioning a new soft polishing pad and processing a substrate on a soft polishing pad is described. The method includes coupling a soft polishing pad to a platen, contacting the processing surface of the soft polishing pad with a conditioning disk, applying a pressure conditioning disk, removing the conditioning disk from contact with the processing surface of the soft polishing pad, and contacting a first substrate with the processing surface of the soft polishing pad to perform a polishing process on the first substrate.

    摘要: Embodiments described herein relate to removing material from a substrate. More particularly, the embodiments described herein relate to polishing or planarizing a substrate by a chemical mechanical polishing process. In one embodiment, a method of chemical mechanical polishing (CMP) of a substrate is provided. The method comprises exposing a substrate having a conductive material layer formed thereon to a polishing solution comprising phosphoric acid, one or more chelating agents, one or more corrosion inhibitors, and one or more oxidizers, forming a passivation layer on the conductive material layer, providing relative motion between the substrate and a polishing pad and removing at least a portion of the passivation layer to expose a portion of the underlying conductive material layer, and removing a portion of the exposed conductive material layer.
