    摘要: A MOS transistor with a laser-patterned metal gate, and methods for its manufacture. The method generally includes forming a layer of metal-containing material on a dielectric film, wherein the dielectric film is on an electrically functional substrate comprising an inorganic semiconductor; laser patterning a metal gate from the metal-containing material layer; and forming source and drain terminals in the inorganic semiconductor in locations adjacent to the metal gate. The transistor generally includes an electrically functional substrate; a dielectric film on at least portions of the electrically functional substrate; a laser patterned metal gate on the dielectric film; and source and drain terminals comprising a doped inorganic semiconductor layer adjacent to the metal gate. The present invention advantageously provides MOS thin film transistors having reliable electrical characteristics quickly, efficiently, and/or at a low cost by eliminating one or more conventional photolithographic steps.

    摘要: A method for making an electronic device, such as a MOS transistor, including the steps of forming a plurality of semiconductor islands on an electrically functional substrate, printing a first dielectric layer on or over a first subset of the semiconductor islands and optionally a second dielectric layer on or over a second subset of the semiconductor islands, and annealing. The first dielectric layer contains a first dopant, and the (optional) second dielectric layer contains a second dopant different from the first dopant. The dielectric layer(s), semiconductor islands and substrate are annealed sufficiently to diffuse the first dopant into the first subset of semiconductor islands and, when present, the second dopant into the second subset of semiconductor islands.
