摘要： Radio frequency identification (RFID) tags and processes for manufacturing the same. The RFID device generally includes (1) a metal antenna and/or inductor; (2) a dielectric layer thereon, to support and insulate integrated circuitry from the metal antenna and/or inductor; (3) a plurality of diodes and a plurality of transistors on the dielectric layer, the diodes having at least one layer in common with the transistors; and (4) a plurality of capacitors in electrical communication with the metal antenna and/or inductor and at least some of the diodes, the plurality of capacitors having at least one layer in common with the plurality of diodes and/or with contacts to the diodes and transistors. The method preferably integrates liquid silicon-containing ink deposition into a cost effective, integrated manufacturing process for the manufacture of RFID circuits. Furthermore, the present RFID tags generally provide higher performance (e.g., improved electrical characteristics) as compared to tags containing organic electronic devices.

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 MOS RF surveillance and/or identification tag, and methods for its manufacture and use. The tag generally includes an interposer, an antenna and/or inductor on the interposer, and integrated circuitry on the interposer in a location other than the antenna and/or inductor. The integrated circuitry generally has a lowest layer in physical contact with the interposer surface. The method of manufacture generally includes forming a lowest layer of integrated circuitry on an interposer, forming successive layers of the integrated circuitry on the lowest layer of integrated circuitry, and attaching an electrically conductive functional layer to the interposer. Alternatively, an electrically conductive structure may be formed from a functional layer attached to the interposer. The method of use generally includes causing and/or inducing a current in the present tag sufficient for it to generate, reflect or modulate a detectable electromagnetic signal, detecting the signal, and optionally, processing information conveyed by the detectable electromagnetic signal. The present invention advantageously provides a low cost RFID tag capable of operating at MHz frequencies that can be manufactured in a shorter time period than conventional RFID tags that manufacture all active electrical devices on a conventional wafer.
