  • Patent number: 8178380
    Abstract: Phase change devices, and particularly multi-terminal phase change devices, include first and second active terminals bridged together by a phase-change material whose conductivity can be modified in accordance with a control signal applied to a control electrode. This structure allows an application in which an electrical connection can be created between the two active terminals, with the control of the connection being effected using a separate terminal or terminals. Accordingly, the resistance of the heater element can be increased independently from the resistance of the path between the two active terminals. This allows the use of smaller heater elements thus requiring less current to create the same amount of Joule heating per unit area. The resistance of the heating element does not impact the total resistance of the phase change device.

  • Publication number: 20110315981
    Abstract: A microbolometer includes a micro-bridge structure for uncooling infrared or terahertz detectors. The thermistor and light absorbing materials of the micro-bridge structure are the vanadium oxide-carbon nanotube composite film formed by one-dimensional carbon nanotubes and two-dimensional vanadium oxide film. The micro-bridge is a three-layer sandwich structure consisting of a layer of amorphous silicon nitride base film as the supporting and insulating layer of the micro-bridge, a layer or multi-layer of vanadium oxide-carbon nanotube composite film in the middle of the micro-bridge as the heat sensitive and light absorbing layer of the microbolometer, and a layer of amorphous silicon nitride top film as the stress control layer and passivation of the heat sensitive film. The microbolometer and method for manufacturing the same can overcome the shortcomings of the prior art, improve the performance of the device, reduce the cost of raw materials and is suitable for large-scale industrial production.

  • Publication number: 20110315880
    Abstract: A TeraMOS sensor based on a CMOS-SOI-MEMS transistor, thermally isolated by the MEMS post-processing, designed specifically for the detection of THz radiation which may be directly integrated with the CMOS-SOI readout circuitry, in order to achieve a breakthrough in performance and cost. The TeraMOS sensor provides a low-cost, high performance THz passive or active imaging system (roughly in the range of 0.5-1.5 THz) by combining several leading technologies: Complementary Metal Oxide Semiconductor (CMOS)-Silicon on Insulator (SOI), Micro Electro Mechanical Systems (MEMS) and photonics. An array of TeraMOS sensors, integrated with readout circuitry and driving and supporting circuitry provides a monolithic focal plane array or imager. This imager is designed in a commercial CMOS-SOI Fab and the MEMS micromachining is provided as post-processing step in order to reduce cost.

    Abstract: A sensor-fitted substrate allowing a sensor-fitted wafer for measuring the temperature or strain to be produced inexpensively, moreover, allowing measurements of the temperature or strain to be carried out with satisfactory accuracy, and a method for producing such a sensor-fitted substrate. An undercoat film is formed on the surface of a substrate, the film being configured, compared to when no undercoat film is formed, to allow the strength of close contact of a dispersed nano-particle ink with the substrate to be increased, the diffusion of the dispersed nano-particle ink into the substrate to be suppressed, and the growth of metal crystal particles contained in the dispersed nano-particle ink to be suppressed. A wiring pattern of the sensor is traced on the surface of the undercoat film of the substrate surface by using the dispersed nano-particle ink, and the dispersed nano-particle ink is baked and metalized.
