  • Publication number: 20070128992
    Abstract: Embodiments of a flexible pad conditioner for conditioning a processing pad are provided. The pad conditioner includes an arc-shaped member having an abrasive bottom surface configured for conditioning the processing pad. Means are provided to apply a downward force as well as to oscillate the pad conditioner. Further means may be provided to vary the downward force along the length of the pad conditioner. In one embodiment, a plurality of actuators may be coupled to a top surface of the member and adapted to selectively provide an independently controllable force against the member to finely control the conditioning profile.

  • Patent number: 7175505
    Abstract: Aspects of the present invention include a method and an apparatus that may be utilized to adjust processing times in a substrate processing system. In one embodiment of the present invention, a pre-processing thickness measurement of a substrate while the substrate is in one of the polishing stations is taken. Then the substrate is processed in the polishing system for a predetermined processing time. A post-processing thickness measurement is taken while the substrate is in one of the polishing stations. A removal rate is calculated based on the pre-processing and the post-processing measurements and the predetermined processing time. A processing time is adjusted for one or more of the polishing stations based on the removal rate for use in subsequent processing of a production substrate.

  • Patent number: 7115024
    Abstract: A platen for chemical mechanical polishing of a substrate includes a surface upon which a polishing pad can be placed, a support structure, and a controller. The surface has a first region and a second region and is operable to exert force against the polishing pad during polishing. The support structure is located beneath the second region and is operable to cause the second region to exert more force than the first region. The controller is operable to adjust the amount of force that is exerted by the second region.

  • Patent number: 7104267
    Abstract: A process for treating a copper or copper alloy substrate surface with a composition and corrosion inhibitor solution to minimize defect formation and surface corrosion, the method including applying a composition including one or more chelating agents, a pH adjusting agent to produce a pH between about 3 and about 11, and deionized water, and then applying a corrosion inhibitor solution. The composition may further comprise a reducing agent and/or corrosion inhibitor. The method may further comprise applying the corrosion inhibitor solution prior to treating the substrate surface with the composition.

  • Patent number: 7040971
    Abstract: A carrier head for a chemical mechanical polishing apparatus is described. The carrier head has a base, a rigid body, a membrane and a pressurizing structure. The rigid body is movable relative to the base and includes a downwardly-extending projection. The membrane has a mounting surface for a substrate. The membrane extends below the base to provide a chamber between the base and the membrane. The pressurizing structure applies a downward pressure on the rigid body to cause a lower surface of the rigid body to press on an inner surface of the membrane.
