  • Patent number: 9421617
    Abstract: A rotary chuck adapted to hold a substrate. The rotary chuck has a rotatable chuck portion and an edge grip having a movable grip member movably mounted to the rotatable chuck portion, the moveable grip member being substantially free moving so that rotation of the rotating chuck portion causes the moveable grip member to move in a plane substantially aligned with a surface of the substrate to engage the substrate in a engaged position. A resilient element is coupled to the moveable grip member, the resilient member biasing the grip member to a disengaged position.

  • Patent number: 9303329
    Abstract: Techniques disclosed herein include an electro-chemical deposition apparatus that provides an efficient circulation system, chemical management that provides reliable and uniform plating, and a configuration that provides short maintenance times and greater tool availability. Techniques include a processing tank containing an anolyte fluid, and one or more plating cells each having a catholyte fluid compartment with a circulation path that connects to a separate or remote catholyte reservoir. Thus, with such a configuration, a single pump can be used to flow catholyte (via manifolds) through one or more plating cells. Thus, with the catholyte reservoir maintained off board, instead of dumping catholyte over a weir into a reservoir, catholyte fluid—after flowing through a plating cell—is returned to the catholyte reservoir.

  • Patent number: 9293356
    Abstract: A system for fluid processing substrate surfaces arrayed in a fluid having a process section with a frame having a plurality of process elements to process the substrate surfaces without contacting the substrate surfaces. A substrate holder assembly having a holder frame and a number of substrate holders, each of which is coupled to the holder frame and is configured for holding a substrate so that each substrate holder holds a different substrate for transport as a unit with the substrate holder assembly to and from the process section. The substrate holder assembly and each substrate holder are removably coupled to the process section frame, and the substrate holders of the substrate holder assembly are movable relative to the holder frame and positionable in repeatable alignment with respect to a predetermined feature of the process section and independent of positioning of the holder frame with respect to the process section.

    Abstract: A system for fluid processing substrate surfaces arrayed in a fluid having a process section with a frame having a plurality of process elements to process the substrate surfaces without contacting the substrate surfaces and a substrate holder assembly having a number of substrate holders and configured for transporting substrates as a unit. The substrate holder assembly and each of the substrate holders are configured for removable coupling to the process section frame, each substrate holder configured to hold at least one of the substrates. The process section frame has alignment features disposed so that, on coupling of the substrate holder assembly with the process section frame, the alignment features interface with each substrate holder of the substrate holder assembly and locate each substrate holder in repeatable alignment, at corresponding coupling of each substrate holder and the process section frame, with respect to a predetermined feature of the process section.

  • Patent number: 8967935
    Abstract: A substrate loader adapted to load and unload a substrate to and from a moveable holder having a seal. The substrate loader has a base and a holder support frame coupled to the base, the holder support frame adapted to repeatably position the moveable holder relative to a predetermined datum. The substrate transport is coupled to the base and having a substrate chuck and adapted to move and transport the substrate relative to the holder. The substrate transport is deterministically positioned relative to the predetermined datum and is adapted to move the substrate from a first position, with the substrate captured by the moveable holder, to a second position with the substrate disengaged from the holder and the seal, the substrate transport movement of the substrate from the first to the second position effecting disengagement from the holder and the seal substantially without contacting the substrate.

  • Publication number: 20150047674
    Abstract: Techniques disclosed herein include a method and apparatus for stripping resist from a substrate without using high concentrations of toxic chemicals and without needing frequent bath replacement. Techniques include using a chemistry that lifts-off the resist, without substantially dissolving the resist, coupled with mechanically breaking removed resist into small particles using mechanical agitation and high fluid flow. Resist particles can then be removed from the vicinity of the wafer by a high-flow circulation out of a processing tank. Circulating flow can then be filtered to remove the resist particles from the circulating fluid and reintroduced into the processing tank. A filtering system can also remove particles from filters either during circulation or with circulation stopped.

  • Patent number: 8858755
    Abstract: A substrate edge bevel etch module for etching a material from a peripheral edge of a substrate with an etchant is described. The substrate edge bevel etch module includes a rotatable substrate holder having a support for a substrate, and a surface tension etch applicator comprising a wetted etching surface opposing a substrate surface proximate an edge of the substrate when the surface tension etch applicator is located proximate to the edge of the substrate. The surface tension etch applicator further includes an etchant dispensing portion, proximate the wetted etching surface, which dispenses an etchant in a region between the wetted etching surface and the substrate surface and wet at least a portion of the wetted etching surface and the substrate surface. A spacing between the wetted etching surface and the substrate surface is selected to retain the etchant using surface tension forces and form a meniscus there between.

  • Patent number: 8425687
    Abstract: A method and apparatus for wetting the surface of a workpiece is disclosed. The apparatus includes a chamber with a vacuum port and a fluid port and a workpiece holder including a body, a ring, and a port. The body includes a surface and defines a cavity extending from the surface. The ring is adapted to retain the workpiece on the surface of body over the cavity. The ring forms a fluid seal relative to the workpiece and to the workpiece holder. The port is defined in the body and in communication with the cavity. The port affects pressure in the cavity to minimize a pressure differential between the front and back surfaces of the workpiece. The fluid port is in communication with the chamber. The fluid port delivers a fluid (e.g., a substantially degassed fluid) to wet the front surface of the workpiece during operation of the chamber at a reduced pressure relative to atmosphere.
