Abstract: PROBLEM TO BE SOLVED: To achieve a trade-off between resolution and sensitivity, and pixel size or packing ratio and circuit complexity. SOLUTION: A circuit comprising a sensor 12, an amplifier connected by an output of the sensor 12 so as to control the amplifier, and a sensor-reset connected to the sensor 12 selectively resetting an electric charge in the sensor 12, and converting the data of the sensor 12 to an electrical signal can be improved by trading off the sensor-reset containing a reset-transistor with its channel region formed by a conductive material having a first structural state the amplifier containing an amplifier transistor 16 with its channel region formed by a conductive material having a converted first structural state, and the amplifier transistor 16 and the reset transistor formed on an common substrate.
