  • Patent number: 10332686
    Abstract: High precision capacitors and methods for forming the same utilizing a precise and highly conformal deposition process for depositing an insulating layer on substrates of various roughness and composition. The method generally comprises the steps of depositing a first insulating layer on a metal substrate by atomic layer deposition (ALD); (b) forming a first capacitor electrode on the first insulating layer; and (c) forming a second insulating layer on the first insulating layer and on or adjacent to the first capacitor electrode. Embodiments provide an improved deposition process that produces a highly conformal insulating layer on a wide range of substrates, and thereby, an improved capacitor.

  • Patent number: 9400953
    Abstract: Methods, algorithms, processes, circuits, and/or structures for laser patterning suitable for customized RFID designs are disclosed. In one embodiment, a method of laser patterning of an identification device can include the steps of: (i) depositing a patternable resist formulation on a substrate having configurable elements and/or materials thereon; (ii) irradiating the resist formulation with a laser tool sufficiently to change the solubility characteristics of the resist in a developer; and (iii) developing exposed areas of the resist using the developer. Embodiments of the present invention can advantageously provide a relatively low cost and high throughput approach for customized RFID devices.

  • Patent number: 8912890
    Abstract: The disclosure relates to surveillance and/or identification devices having capacitors connected in parallel or in series, and methods of making and using such devices. Devices with capacitors connected in parallel, where one capacitor is fabricated with a relatively thick capacitor dielectric and another is fabricated with a relatively thin capacitor dielectric achieve both a high-precision capacitance and a low breakdown voltage for relatively easy surveillance tag deactivation. Devices with capacitors connected in series result in increased lateral dimensions of a small capacitor. This makes the capacitor easier to fabricate using techniques that may have relatively limited resolution capabilities.

  • Patent number: 8461628
    Abstract: 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.
