  • Patent number: 7604718
    Abstract: A dynamically configurable electrode includes a first planar electrode and a planar array of pixels in a different plane, wherein a polarizable liquid medium (including electrolyte solutions) is to reside in the gap between electrodes. The pixels are individually addressable by a time-varying voltage, and adjacent pixels receive, at any instant in time, either the same voltage waveform or a different voltage waveform. Adjacent pixels receiving different voltage waveforms generate corresponding movement of dipolar entities, including dipolar particles, ions, or dipolar molecules in the polarizable liquid medium between the electrodes, which can in turn generate fluid flow and movement of particles suspended in the fluid along the planar array surface.

  • Patent number: 7592536
    Abstract: A solar cell structure has a solar cell unit structure including a heat sink, and a solar cell having a front side, a back side, and a solar-cell projected area coverage on the heat sink. The solar cell has an active semiconductor structure that produces a voltage between the front side and the back side when the front side is illuminated. An intermediate structure is disposed between and joined to the back side of the solar cell and to the heat sink. The intermediate structure has an intermediate-structure projected area coverage on the heat sink and includes a by-pass diode having a diode projected area coverage on the heat sink. The diode projected area coverage on the heat sink may be substantially the same as the intermediate-structure projected coverage on the heat sink. Alternatively, the diode projected area coverage on the heat sink maybe less than the solar-cell projected area coverage on the heat sink, and the intermediate structure further includes a substrate coplanar with the by-pass diode.

  • Patent number: 7588674
    Abstract: Some embodiments of the present invention provide processes and apparatus for electrochemically fabricating multilayer structures (e.g. mesoscale or microscale structures) with improved endpoint detection and parallelism maintenance for materials (e.g. layers) that are planarized during the electrochemical fabrication process. Some methods involve the use of a fixture during planarization that ensures that planarized planes of material are parallel to other deposited planes within a given tolerance. Some methods involve the use of an endpoint detection fixture that ensures precise heights of deposited materials relative to an initial surface of a substrate, relative to a first deposited layer, or relative to some other layer formed during the fabrication process. In some embodiments planarization may occur via lapping while other embodiments may use a diamond fly cutting machine.

  • Patent number: 7585399
    Abstract: In one embodiment, a magnetron sputtering apparatus includes one or more magnet arrays for moving ions or charged particles on at least two plasma discharge paths on a target. Charged particles on one of the plasma discharge paths are moved in one direction, while charged particles on the other plasma discharge path are moved in the opposite direction to reduce rotational shifting of deposition flux on the patterned substrates. The plasma discharge paths may be formed by two symmetric magnet arrays or a single asymmetric magnet array rotated from behind the target.

  • Patent number: 7575664
    Abstract: A cathode potential is applied to a conductive layer formed on a substrate having a depression pattern. A plating solution in electrical contact with an anode is supplied to the conductive layer to form a plating film on the conductive layer. At this time, the plating solution is supplied by causing an impregnated member containing the plating solution to face the conductive layer. Since the plating solution stays in the depression, a larger amount of plating solution is supplied than on the upper surface of the substrate, and the plating rate of the plating film in the depression increases. Consequently, the plating film can be preferentially formed in the depression such as a groove or hole.

  • Patent number: 7575662
    Abstract: The invention relates to a method for operating a magnetron sputter cathode, in particular a tube cathode or several tube cathodes forming an array. In such cathodes a target passes through a magnetic field, whereby induction currents flow in the target which distort the magnetic field. This results in the nonuniform coating of a substrate. By having the relative movement between magnetic field and target alternately reverse its direction, the effect of the magnetic field distortion can be compensated. This yields greater uniformity of the coating on a substrate to be coated.
