LIGHT LEAKAGE COMPENSATING UNIT IMAGE SENSORS, IMAGE SENSOR ARRAYS INCLUDING THE UNIT IMAGE SENSORS, AND METHODS FOR COMPENSATING FOR LIGHT LEAKAGE OF THE IMAGE SENSOR ARRAYS

摘要

A light leakage compensating unit image sensor in a back side illumination method includes a photodiode and a storage diode, in which light input to a back side of the unit image sensor is received only by an area forming an electrode of the photodiode, and an area for forming another electrode of the photodiode and an area for forming two electrodes of the storage diode are separated from each other by a well, thereby compensating light leakage.
