  • Patent number: 9698184
    Abstract: With an image sensor in which the amplifier circuit is disposed at each pixel, there is such an issue that the threshold voltage of the transistor fluctuates so that the signal voltage fluctuates because a voltage is continuously applied between the source and the gate of the transistor at all times when using the amorphous thin film semiconductor as the transistor that constitutes an amplifier circuit. The gate-source potential of the TFT that constitutes the amplifier circuit is controlled so that the gate terminal voltage becomes smaller than the source terminal voltage in an integrating period where the pixels accumulate the signals, and controlled so that the gate terminal voltage becomes larger than the source terminal voltage in a readout period where the pixels output the signals.

  • Patent number: 9664642
    Abstract: The ion sensors using TFT or MOSFET are low in the measurement sensitivity so that it is difficult to detect an extremely small amount of sensing-target substance. A TFT ion sensor includes both a gate electrode (a silicon substrate) and a reference electrode, in which the electrostatic capacitance of a gate insulating film (a thermal oxide film) is set to be larger than the electrostatic capacitance of an ion sensitive insulating film. Therefore, it is possible to detect the concentration of ions, hormones, and the like in a sensing-target substance from the shift in the threshold voltage of the gate-source voltage to source-drain current property.

    Abstract: A TFT biosensor includes a gate electrode (silicon substrate), a reference electrode, and enzyme that is fixed to an insulating substrate spatially separated from the gate electrode and the reference electrode. A pH variation in the vicinity of an ion-sensitive insulating film is induced by a reaction between the enzyme and a sensing object material. The TFT biosensor can detect a concentration of the sensing object material with high sensitivity by detecting the pH variation as a threshold voltage shift of characteristics of a gate-source voltage to a source-drain current.
