A process electrolyte recirculation compartment is disposed in the frame configured so that the process electrolyte is recirculating between the replenishment module and the deposition apparatus. An anode compartment is coupled to the process electrolyte recirculation compartment having the second anode, that is a soluble anode, for immersion in a secondary anolyte, and having a first ion exchange membrane being a cationic member separating the secondary anolyte from the process electrolyte. A cathode compartment is provided in the frame coupled to the process electrolyte recirculation compartment having a second cathode for immersion in a secondary catholyte, and having a second ion exchange membrane being a monovalent selective membrane separating the secondary catholyte from the process electrolyte.

摘要: An electrochemical deposition apparatus adapted to deposit metal onto a surface of a substrate, the apparatus has a frame configured for holding a process electrolyte. A substrate holder is removably coupled to the frame, the substrate holder supporting the substrate in the process electrolyte. An anode fluid compartment is removably coupled to the frame and containing an anolyte and having an anode facing the surface of the substrate, the anode fluid compartment further having a ion exchange membrane disposed between the anode and the surface of the substrate, the anode fluid compartment removable from the frame as a unit with the ion exchange membrane and the anode. The holder, the anode and the membrane are arranged in the frame so that ions from the anode pass through the ion exchange membrane into and primarily replenish ions in the process electrolyte depleted by ion deposition onto the surface of the substrate.

摘要: A method and system for coating the interior surfaces of microscale hole features fabricated into the substantially planar surface of a work piece. The method comprises providing a work piece with a barrier metal coating that is substantially continuous and uniform both along the planar surface of the work piece and the inner surfaces of the microscale hole features wherein said barrier metal coating is applied by a substantially surface reaction limited process. The workpiece is provided with a coating, on the planar surface of the work piece, of a thick metal layer anchored to the barrier metal coat and disposed to provide substantially uniform electrical conduction capability to the microscale features located throughout and across the workpiece. An electrical contact path is provided to the electrically conductive coating at the perimeter of the work piece. The workpiece is immersed in a chemical bath, causing said chemical bath to fully contact the interior surfaces of the microscale hole features, said chemical bath containing metal ions suitable for electrodeposition. An electric potential is applied at the perimeter of the work piece to cause electrodeposition of metal ions onto all surfaces of the work piece including the interior surfaces of the microscale hole features to a predetermined finish coating in one step.
