    摘要: A carrier head and a method of cleaning the carrier head are disclosed. The carrier head may have one or more openings through a sidewall that extend into a cavity within the carrier head using a fluid passage. The openings may each have a lip. The lip may have a chamfered edge. Additionally, a fluid passage may slope generally downward from the openings to the cavity. The chamfered lips and the sloped fluid passage reduce back splashing and help ensure that sufficient rinsing fluid reaches the cavity to rinse polishing fluid and particles from the carrier head. The present invention relates to carrier heads for polishing or planarizing semiconductor substrates by chemical mechanical polishing (CMP) or electrochemical mechanical polishing (ECMP). The cavities in the carrier head are cleaned by rinsing fluid (i.e., liquid or gas) from inside the cavity towards a substrate receiving side of the carrier head.

    摘要: Polishing compositions and methods for removing conductive materials and barrier materials from a substrate surface are provided. In one aspect, a full sequence electrochemical mechanical planarization technique is provided. In another aspect, a hybrid planarization technique using combination of at least one chemical mechanical polishing process and at least one electrochemical mechanical polishing process is provided. In addition, a multi-step polishing process for polishing a substrate surface using at least two oxidizers in one or more polishing composition is described. The polishing composition may be used in the full sequence or the hybrid planarization technique. The polishing compositions and methods described herein improve the effective removal rate of materials from the substrate surface with a reduction in planarization defects.

    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: A method for processing a substrate having a conductive layer disposed thereon is provided. The substrate is coupled with a planarizing head. The planarizing head is moved to a position above a polishing pad assembly. The planarizing pad is positioned relative to the polishing pad assembly without applying a voltage to the substrate. A first voltage is applied to the substrate for a first time period. A second voltage is applied to the substrate for a second time period in order to remove a portion of the conductive layer, wherein the second voltage is greater than the first voltage. In certain embodiments, applying a first voltage to the substrate further comprises forming a uniform passivation layer on the conductive layer.
