CIRCUIT AND PHOTO SENSOR OVERLAP FOR BACKSIDE ILLUMINATION IMAGE SENSOR
摘要
A backside illuminated ("BSI") imaging sensor pixel (400) includes a photodiode (420) region and pixel circuitry (430) The photodiode region is disposed within a semiconductor die for accumulating an image charge in response to light incident upon a backside of the BSI imaging sensor pixel. The pixel circuitry includes transistor pixel circuitry disposed within the semiconductor die between a frontside of the semiconductor die and the photodiode region. At least a portion of the pixel circuitry overlaps the photodiode region.
