    Abstract: The present invention relates to methods and apparatus for plating a conductive material on a semiconductor substrate by rotating pad or blade type objects in close proximity to the substrate, thereby eliminating/reducing dishing and voids. This is achieved by providing pad or blade type objects mounted on cylindrical anodes or rollers and applying the conductive material to the substrate using the electrolyte solution disposed on or through the pads, or on the blades. In one embodiment of the invention, the pad or blade type objects are mounted on the cylindrical anodes and rotated about a first axis while the workpiece may be stationary or rotate about a second axis, and metal from the electrolyte solution is deposited on the workpiece when a potential difference is applied between the workpiece and the anode. In another embodiment of the present invention, the plating apparatus includes an anode plate spaced apart from the cathode workpiece. Upon application of power to the anode plate and the cathode workpiece, the electrolyte solution disposed in the plating apparatus is used to deposit the conductive material on the workpiece surface using cylindrical rollers having the pad or blade type objects.

    Abstract: Conductive structures in features of an insulator layer on a substrate are fabricated by a particular process. In this process, a layer of conductive material is applied over the insulator layer so that the layer of conductive material covers field regions adjacent the features and fills in the features themselves. A grain size differential between the conductive material which covers the field regions and the conductive material which fills in the features is then established by annealing the layer of conductive material. Excess conductive material is then removed to uncover the field regions and leave the conductive structures. The layer of conductive material is applied so as to define a first layer thickness over the field regions and a second layer thickness in and over the features. These thicknesses are dimensioned such that d1≦0.5d2, with d1 being the first layer thickness and d2 being the second layer thickness. Preferably, the first and second layer thicknesses are dimensioned such that d1≦0.3d2.

    Abstract: The methods and systems described provide for radiation assisted material deposition, removal, and planarization at a surface, edge, and/or bevel of a workpiece such as a semiconductor wafer. Exemplary processes performed on a workpiece surface having topographical features include radiation assisted electrochemical material deposition, which produces an adsorbate layer outside of the features to suppress deposition outside of the features and to encourage, through charge conservation, deposition into the features to achieve, for example, a planar surface profile. A further exemplary process is radiation assisted electrochemical removal of material, which produces an adsorbate layer in the features to suppress removal of material from the features and to encourage, through charge conservation, removal of material outside of the features so that, for example, a planar surface profile is achieved.

    Abstract: An apparatus capable of assisting in controlling an electrolyte flow and an electric field distribution used for processing a substrate is provided. It includes a rigid member having a top surface of a predetermined shape and a bottom surface. The rigid member contains a plurality of channels, each forming a passage from the top surface to the bottom surface, and each allowing the electrolyte and electric field flow therethrough. A pad is attached to the rigid member via a fastener. The pad also allows for electrolyte and electric field flow therethrough to the substrate.

    Abstract: A layer structure usable in manufacturing an integrated circuit is made, in a single apparatus, by a particular process in which a patterned substrate is provided. An electrolyte solution, out of which a conductive material can be plated under an applied potential, is supplied over a surface of the patterned substrate, and a potential is applied so as to deposit a film of the conductive material out of the electrolyte solution and over the surface of the patterned substrate. The film of conductive material is preferably polished as it is deposited. The conductive material is then removed from field regions of the patterned substrate, while deposits of the conductive material are left in features defined in the patterned substrate. The deposits of the conductive material are then electrically isolated, resulting in the layer structure.

    Abstract: A process of electrodepositing a substantially flat conductive layer on a workpiece surface is provided. In the process, various transition current densities are determined experimentally by evaluating the effects of the plating current density on gap fill profile in the smallest cavities with the largest tendency to over-plate on the substrate. After determining the transition currents on experimental wafers or dies, an electrochemical plating process is performed to apply selected transition current densities as process current densities to form a substantially flat profile over the smallest cavities.
