  • System and method for formation of electrical conductors on a substrate
    Patent number: 8635761
    Abstract: A method for printing an electrical conductor on a substrate has been developed. In the method, a reverse image of the electrical conductor pattern is printed on a substrate with an electrically non-conductive material to form a second pattern that exposes a portion of the surface area of the substrate. The entire surface area of the substrate is then covered with an electrically conductive material. The non-conductive material of the reverse image electrically isolates the electrically conductive material covering the reverse image from the electrically conductive material covering the second pattern.

  • Method for coating dielectric composition for fabricating thin-film transistors
    Patent number: 8623447
    Abstract: An electronic device, such as a thin-film transistor, includes a substrate and a dielectric layer formed from a dielectric composition. The dielectric composition includes a dielectric material, a crosslinking agent, and a thermal acid generator. In particular embodiments, the dielectric material comprises a lower-k dielectric material and a higher-k dielectric material. When deposited, the lower-k dielectric material and the higher-k dielectric material form separate phases. The thermal acid generator allows the dielectric layer to be cured at relatively lower temperatures and/or shorter time periods, permitting the selection of lower-cost substrate materials that would otherwise be deformed by the curing of the dielectric layer.
