  • Patent number: 9214375
    Abstract: An apparatus is provided for lifting a substrate. The apparatus comprises a first piece and a second piece. The apparatus further comprises a set of first contact points in a plane and a set of second contact points, where at least one contact point from each set is present on the first piece and the second piece. The apparatus also comprises an actuator that translates the first piece, substantially parallel to the plane, between a first position and a second position relative to the second piece. Additionally, the first position arranges the set of first contact points so that all of the contact points of the set of first contact points are able to engage the substrate, and the second position arranges the set of second contact points so that all of the contact points of the second set of contact points are able to engage the substrate.

  • Patent number: 8334191
    Abstract: A system for treating distinct batches of workpieces to serial procedures comprises first and second multi-site structures. In each multi-site structure the sites are rotatable for alignment in turn with loading and unloading stations together constituting treatment or process stations. Workpieces of a batch are loaded onto all of the treatment sites and then simultaneously and identically treated by operation of treatment stations with which the process sites are aligned. After treatment in the first structure, workpieces of a batch are transferred from the unloading stations of the first structure to the loading stations of the second structure for further processing.

  • Patent number: 8207047
    Abstract: A system for simultaneously treating multiple workpieces is configured with treatment sites, configured to hold respective workpieces, fixed on a rotatable base. Treatment stations are equipped with respective active components operable simultaneously to treat respective workpieces identically on respective aligned treatment sites. For loading and unloading the treatment sites are rotated through distinct loading and unloading stations of the treatment stations which allow loading of a second batch while a first batch is being unloaded.

  • Patent number: 8021215
    Abstract: A carrier head that has a housing, a base assembly, a retaining ring, a carrier ring, and a flexible membrane is described. The base assembly is vertically movable relative to the housing. The retaining ring is connected to and vertically movable relative to the base assembly and has a lower surface configured to contact a polishing pad and an inner surface configured to circumferentially surround the edge of a substrate to retain the substrate. The carrier ring is connected to and vertically fixed relative to the base assembly, circumferentially surrounds the retaining ring to prevent lateral motion of the retaining ring, and has a bottom surface configured to contact a polishing pad.
