Image sensor and method of manufacturing the same

摘要

An image sensor has a CdTe plate, a plurality of hole-type electrodes, and a voltage-applying unit. The hole-type electrodes are arranged at predetermined intervals in the direction of thickness. The voltage-applying unit applies a voltage to the hole-type electrodes. One of the electrodes is not adjacent to any other electrode and is used as an anode. The remaining electrodes are used as cathodes. A sensor-element array is provided on the detecting surface of the image sensor. The array comprises a plurality of sensor elements arranged in the form of a matrix. Each sensor element comprises an anode, a plurality of cathodes, and CdTe lying between the anode and the cathodes.
