  • AN INTEGRATED SENSOR DEVICE FOR CHARGE DETECTION
    Publication number: 20160153932
    Abstract: A semiconductor based integrated sensor device includes: a lateral insulating-gate field effect transistor (MOSFET) connected in series to the base of a vertical bipolar junction transistor (BJT) wherein the drain-drift-region of the MOSFET is part of the base-region of the BJT within the semiconductor substrate thus making electrical contact to the base of the BJT and the distance of the drain-drift-region of the MOSFET to the emitter of the BJT exceeds the vertical distance between the emitter and any buried layer, serving as collector, and the breakdown voltage of the device being determined by the BVCEO of the vertical BJT.
