    Abstract: Embodiments of methods and apparatus for filling a feature disposed in a substrate are disclosed herein. In some embodiments, a method for filling a feature disposed in a substrate includes (a) depositing a metal within the feature to a first predetermined thickness in a first process chamber; (b) depositing the metal within the feature to a second predetermined thickness in a second process chamber; (c) etching the metal deposited in (b) to remove an overhang of the metal at a top of the feature in a third process chamber different than the first and second process chambers; and (d) subsequent to (c), filling the feature with the metal in a fourth process chamber different than the first and third process chambers.

    Abstract: A method for forming metallization in a workpiece includes electrochemically depositing a second metallization layer on the workpiece comprising a nonmetallic substrate having a dielectric layer disposed over a substrate and a continuous first metallization layer disposed on the dielectric layer and having at least one microfeature comprising a recessed structure, wherein the first metallization layer at least partially fills a feature on the workpiece, where the first metallization layer is a cobalt or nickel metal layer, and wherein the second metallization layer is a cobalt or nickel metal layer that is different from the metal of the first metallization layer, electrochemically depositing a copper cap layer after filling the feature, and annealing the workpiece to diffuse the metal of the second metallization layer into the metal of the first metallization layer.

    Abstract: A wafer electroplating system has at least one first electroplating chamber having a first electrolyte containing cobalt ions, and is adapted to electroplate a cobalt film onto a wafer at a first deposition rate. A second electroplating chamber has a second electrolyte containing cobalt ions, and is adapted to electroplate a cobalt film onto the wafer at a second deposition rate faster than the first deposition rate. The first and second electroplating chambers are within an enclosure of a processing system. A robot moves a wafer among the first and second electroplating chambers.

    Abstract: An electroplating apparatus has one or more membrane tube rings which act as electric field shields, to provide advantageous plating characteristics at the perimeter of a work piece. The membrane tube rings may be filled with fluids having different conductivity, to change the shielding effect as desired for electroplating different types of substrates. The membrane tube rings may optionally be provided in or on a diffuser plate in the vessel of the apparatus.
