  • Patent number: 9812296
    Abstract: Some embodiments provide a magnetron sputtering apparatus including a vacuum chamber within which a controlled environment may be established, a target comprising one or more sputterable materials, wherein the target includes a racetrack-shaped sputtering zone that extends longitudinally along a longitudinal axis and comprises a straightaway area sandwiched between a first turnaround area and a second turnaround area, a gas distribution system that supplies a first gas mixture to the first turnaround area and/or the second turnaround area and supplies a second gas mixture to the straightaway area, wherein the first gas mixture reduces a sputtering rate relative to the second gas mixture. In some cases, the first gas mixture includes inert gas having a first atomic weight and the second gas mixture includes inert gas having a second atomic weight, wherein the second atomic weight is heavier than the first atomic weight.

  • Patent number: 9748082
    Abstract: A cathode target assembly for use in sputtering target material onto a substrate includes a generally cylindrical target and a magnetic array. The magnetic array is adapted to provide a plasma confinement region adjacent an outer surface of the target. End portions of the magnetic array are adapted to make the shape and strength of the confinement field at the turns of the racetrack closely match the shape and strength of the confinement field along the straight part of the racetrack so as to significantly reduce cross-corner effect.

  • Publication number: 20160111624
    Abstract: A thermoelectric device for use with solar cells or other heat sources. A substrate has a manufactured surface with a plurality of highland features and lowland features. Each highland feature defines a peak adjacent to which there is an interface of two different film regions (formed of two different metals, two different semiconductors, or one metal and one semiconductor). The two film regions diverge away from each other with increasing distance from the interface and terminate at distal end regions. In response to a temperature difference between the interface and the distal end regions, the device produces a voltage.

  • Patent number: 8906206
    Abstract: The invention provides a coater, and methods of using the coater, for depositing thin films onto generally-opposed major surfaces of a sheet-like substrate. The coater has a substrate transport system adapted for supporting the substrate in a vertical-offset configuration wherein the substrate is not in a perfectly vertical position but rather is offset from vertical by an acute angle. The transport system defines a path of substrate travel extending through the coater. The transport system is adapted for conveying the substrate along the path of substrate travel. Preferably, the transport system includes a side support for supporting a rear major surface of the substrate. The preferred side support bounds at least one passage through which coating material passes when such coating material is deposited onto the substrate's rear major surface. Preferably, the coater includes at least one coating apparatus (e.g.
