  • Patent number: 7524406
    Abstract: Although there are several inventions disclosed herein, the present application is directed to a reactor for electrochemically processing a microelectronic workpiece. The reactor comprises a movable electrode assembly that is disposed for movement along a motion path. The motion path includes at least a portion thereof over which the electrode assembly is positioned for processing at least one surface of the microelectronic workpiece. A cleaning electrode is located along the motion path of the movable electrode assembly. In one embodiment, a programmable controller is connected to direct the movable electrode assembly to move to the cleaning electrode during a cleaning cycle. At that time, the programmable controller connects the movable electrode assembly as an anode and the cleaning electrode as a cathode for cleaning of the movable electrode assembly.

  • Publication number: 20060226019
    Abstract: The present invention provides a semiconductor workpiece support and contact assembly for providing localized electrical connections with the device side of the workpiece. The additional contact points help overcome the terminal effect caused by very high sheet resistance of thin barrier layers and enable plating a conformal seed layer or feature filling directly on thin barrier layers. By utilizing the streets that separate individual dice on a workpiece to make electrical connections with the workpiece and provide localized distribution of plating chemistry, the present invention provides a more uniform and conformal metallization layer.

  • Publication number: 20060037855
    Abstract: Processing tools, components of tools, and methods of making and using such devices for electrochemical processing of microelectronic workpieces. One aspect of the invention is directed toward reaction vessels for electrochemical processing of microelectronic workpieces, processing stations including such reaction vessels, and methods for using these devices. For example, one embodiment of a reaction vessel includes an outer container having an outer wall, a first outlet configured to introduce a primary fluid flow into the outer container, and at least one second outlet configured to introduce a secondary fluid flow into the outer container separate from the primary fluid flow. The reaction vessel can also include at least one electrode, and it can also have a field shaping unit.

  • Publication number: 20050155864
    Abstract: An electrochemical processing chamber which can be modified for treating different workpieces and methods for so modifying electrochemical processing chambers. In one particular embodiment, an electrochemical processing chamber 200 includes a plurality of walls 510 defining a plurality of electrode compartments 520, each electrode compartment having at least one electrode 600 therein, and a virtual electrode unit 530 defining a plurality of flow conduits, with at least one of the flow conduits being in fluid communication with each of the electrode compartments. This first virtual electrode unit 530 may be exchanged for a second virtual electrode unit 540, without modification of any of the electrodes 600, to adapt the processing chamber 200 for treating a different workpiece.

  • Publication number: 20050107971
    Abstract: A processing apparatus for processing a microelectronic workpiece includes a metrology unit and a control, signal-connected to the metrology unit. The control can modify a process recipe or a process sequence of the processing apparatus based on a feed forward or a feed back signal from the metrology unit. A seed layer deposition tool, a process layer electrochemical deposition tool, and a chemical mechanical polishing tool, arranged for sequential processing of a workpiece, can be controlled as an integrated system using one or more metrology units. A metrology unit can be located at each tool to measure workpiece parameters. Each of the metrology units can be used as a feed forward control and/or a feed back control at each of the tools.

  • Publication number: 20050045474
    Abstract: Contact assemblies for electrochemical processing of microelectronic workpieces. The contact assembly (400) can comprise a support member (410) that includes an inner wall (412) which defines an opening (414) configured to receive the work-piece and a plurality of contacts (420). The individual contacts (420) include a conductor (440) and a cover (430). The conductor (440) can comprise a proximal section (435) projecting inwardly into the opening (414) relative to the support member (410), a distal section (436) extending from the proximal section (435), and an inert exterior (444) at least at the distal section (436). The cover (430) comprises a dielectric element that covers at least the proximal section of the conductor, but does not cover at least a portion of the distal section of the core. The exposed portion of the distal section of the core, accordingly, defines a conductive contact site for contacting a conductive layer (e.g., a seed layer) on the workpiece.

  • Publication number: 20030136431
    Abstract: In a post chemical-mechanical polishing (CMP) procedure for cleaning a workpiece, a cleaning solution is delivered to the core of a brush where the solution is absorbed by the brush and then applied by the brush onto the workpiece. The cleaning solution is uniformly applied to the workpiece. The volumes of solutions used in the scrubbing process is reduced. A thin oxide layer is etched. A hydrophilic surface state is maintained. The workpiece is then rinsed and dried in a centrifugal processing between upper and lower rotors. A high level clean is achieved while consumption of rinsing and drying fluids is reduced.
