摘要： 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.

摘要： 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.

摘要： The present invention relates to a method for fabricating high performance chip interconnects and packages by providing methods for depositing a conductive material in cavities of a substrate in a more efficient and time saving manner. This is accomplished by selectively removing portions of a seed layer from a top surface of a substrate and then depositing a conductive material in the cavities of the substrate, where portions of the seed layer remains in the cavities. Another method includes forming an oxide layer on the top surface of the substrate such that the conductive material can be deposited in the cavities without the material being formed on the top surface of the substrate. The present invention also discloses methods for forming multi-level interconnects and the corresponding structures.

摘要： 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.

摘要： 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.

摘要： The present invention applies an electrochemical etching solution to a material layer, preferably a metal layer, disposed on a workpiece, in the presence of a current. This electrochemical etching solution supplies to the material on the substrate surface the species to form an intermediate compound on the surface that can be more easily mechanically removed as intermediate compound fragments than the material. By removing the intermediate compound fragments, the process allows more efficient use of the supplied current to form another layer of intermediate compound that can also be mechanically removed, rather than using the current to result in another compound on the surface of the material that eventually dissolves into the solution. In another aspect of the invention, such intermediate compound particulates are externally generated and used to mechanically remove the surface layer of the material. Such intermediate particulates do not contaminate, and thus allow for more efficient material removal, as well as plating to occur within the same chamber, if desired.
