  • Patent number: 7217345
    Abstract: Production of pure metals through electro-winning and electro-deposition is accomplished by electrolytic deposition of metal over a reusable stainless-steel plate (cathode). Metal is deposited on both faces of the cathode, as well as on its edges, creating problems when removing the deposited metal. Breaking the deposited edges to remove the metal deposited on both faces produces irregular edges, folding and damages to the surface of the cathode, requiring re-processing, increasing costs of the deposited metal, as well as repairs or replacement of the cathodes. This invention includes a structure made of insulating material to which are fixed electrically energizable cathode guidance profiles with a cross-section similar to an omega and which house the edges of the cathodes, holding them in position during the process.

  • Patent number: 7204920
    Abstract: A contact ring for use in electroplating of a substrate material is constructed such that fluid (e.g., electrolyte) is allowed to flow radially away from the axis of a toroidal support ring, thus preventing the trapping of fluids between the substrate and the toroidal support ring. The contact ring is constructed with a series of openings arranged about the circumference of the ring and wherein an electrical contact is placed in the path of each opening so any fluid passing through the opening also passes around the associated electrical contact. Further, the electrical contacts are also placed such that a substrate (e.g., a semiconductor wafer) can be placed inside the support ring so as to electrically contact the electrical contacts. The toroidal support ring has an aerodynamically streamlined cross-section at the openings, such that fluid flows through the openings with reduced aerodynamic drag.

  • Patent number: 6974530
    Abstract: The flow of electrolyte and/or of ions is controlled by a diffuser element provided in a plating reactor, wherein, in one embodiment, the diffuser element comprises a mechanical adjustment mechanism to adjust the effective size of passages of the diffuser element. In another embodiment, the diffuser element comprises at least two patterns of passages that are movable relatively to each other so as to adjust an overlap and thus an effective size of the corresponding passages. Moreover, the path of ions within the plating reactor may be controlled by an electromagnetically driven diffuser element so that a required thickness profile on the workpiece surface may be obtained.

  • Patent number: 6921468
    Abstract: A system for electroplating a semiconductor wafer is set forth. The system comprises a first electrode in electrical contact with the semiconductor wafer and a second electrode. The first electrode and the semiconductor wafer form a cathode during electroplating of the semiconductor wafer. The second electrode forms an anode during electroplating of the semiconductor wafer. A reaction container defining a reaction chamber is also employed. The reaction chamber comprises an electrically conductive plating solution. At least a portion of each of the first electrode, the second electrode, and the semiconductor wafer contact the plating solution during electroplating of the semiconductor wafer. An auxiliary electrode is disposed exterior to the reaction chamber and positioned for contact with plating solution exiting the reaction chamber during cleaning of the first electrode to thereby provide an electrically conductive path between the auxiliary electrode and the first electrode.

  • Patent number: 6864589
    Abstract: A two dimensional vernier is provided along with a method of fabrication. The two dimensional vernier has a reference array patterned into a substrate, or a material overlying the substrate. An active array is patterned into photoresist overlying the substrate or the material. Both the reference array and the active array each comprise a two dimensional array of shapes. A difference between a combination of size or spacing of the shapes in each array determines vernier resolution. Vernier range is determined by a combination of vernier resolution and an integer related to a total number of shapes along a given axis. The two dimensional vernier allows an operator to readily measure the misalignment of a pattern to be processed relative to a previous pattern in two dimensions using a microscope. The two dimensional vernier reduces, or eliminates, repositioning of the microscope to determine both x-axis misalignment and y-axis misalignment.

  • Patent number: 6852208
    Abstract: Deposition of conductive material on or removal of conductive material from a workpiece frontal side of a semiconductor workpiece is performed by providing an anode having an anode area which is to face the workpiece frontal side, and electrically connecting the workpiece frontal side with at least one electrical contact, outside of the anode area, by pushing the electrical contact and the workpiece frontal side into proximity with each other. A potential is applied between the anode and the electrical contact, and the workpiece is moved with respect to the anode and the electrical contact. Full-face electroplating or electropolishing over the workpiece frontal side surface, in its entirety, is thus permitted.
