ABSTRACT:
An image sensor includes a photoelectric converter formed in a semiconductor substrate to generate and integrate charges resulting from incident light, a first charge transmitter transmitting integrated charges to a charge detector, an overflow drain region discharging excess charges generated by the photoelectric converter, and a second charge transmitter transmitting the excess charges to the overflow drain region and having a width which is at least half of a span of the photoelectric converter.
