  • Patent number: 11910715
    Abstract: A poling apparatus for poling a polymer thin film formed on a workpiece carried by a workpiece carrier. The workpiece has multiple grounding electrodes, grounding pads located at its edges, and a polymer thin film including multiple areas each covering only one grounding electrode. The poling apparatus includes, in a poling chamber, a poling source generating a plasma, a shadow mask below the poling source, and a Z-elevator to raise the workpiece carrier toward the shadow mask and poling source. When the workpiece in the workpiece carrier is raised to contact the underside of the shadow mask, multiple openings of the shadow mask expose only the corresponding multiple thin film areas of the workpiece to the plasma; meanwhile, conductive grounding terminals on the underside of the shadow mask electrically connect the grounding pads of the workpiece with carrier electrodes on the workpiece carrier, to ground the workpiece.

  • Patent number: 10050419
    Abstract: A corona polarization (also denoted “poling”) process and associated apparatus polarizes a ferroelectric polymer thin film while monitoring and evaluating a substrate current whose magnitude, slope and noise profile (Barkhausen noise) varies in accordance with phase transformation processes of crystallites within the film and, thereby, provides an indication of the polarization status. The electric current flowing through the microstructures of the thin film can be modeled by an equivalent circuit, within which electrical charges stored in the respective microstructures are denoted by a plurality of discrete components (e.g., capacitors). Alternatively, the process can be modeled in terms of a hysteresis loop of polarization vs. electric field, corresponding to the availability of recombination sites on the thin-film surface.

  • Publication number: 20150232907
    Abstract: An automated toxicity assessment apparatus includes multiple sample plates each configured to hold test wells for holding a test solution comprising a test compound and a test organism. A dispense head holds dispense tips for dispensing test solutions into the test wells in one sample plate at each time. An electronic detector can capture an image of a test solution in one of test wells on a sample plate to establish a dose-response curve for the test organism. A carousal system rotates a first sample plate to a first position under the dispense head to allow the plurality of dispense tips to dispense solutions into the test wells on the first sample plate. The carousal system rotates the first sample plate to a second position to allow the electronic detector to capture an image of a test solution in the one of test wells on the first sample plate.
