  • Patent number: 7827930
    Abstract: An electroless deposition system is provided. The system includes a processing mainframe, at least one substrate cleaning station positioned on the mainframe, and an electroless deposition station positioned on the mainframe. The electroless deposition station includes an environmentally controlled processing enclosure, a first processing station configured to clean and activate a surface of a substrate, a second processing station configured to electrolessly deposit a layer onto the surface of the substrate, and a substrate transfer shuttle positioned to transfer substrates between the first and second processing stations. The system also includes a substrate transfer robot positioned on the mainframe and configured to access an interior of the processing enclosure. The system also includes a substrate a fluid delivery system that is configured to deliver a processing fluid by use of a spraying process to a substrate mounted in the processing enclosure.
    Type: Grant

  • Patent number: 7497767
    Abstract: A carrier head for chemical mechanical polishing is described. The carrier head includes a backing assembly, a housing and a damping material. The backing assembly includes a substrate support surface. The housing is connectable to a drive shaft to rotate with the drive shaft about a rotation axis. In one implementation, the damping material is in a load path between the backing assembly and the housing to reduce transmission of vibrations from the backing assembly to the housing.

  • Publication number: 20040005842
    Abstract: A carrier head for chemical mechanical polishing of a substrate has a flexible membrane extending beneath a base to define a chamber. The flexible membrane provides a substrate receiving surface, and can be configured so that a pressure profile applied to a substrate is substantially insensitive to retaining ring wear.
