METHODS AND APPARATUS FOR A GLOBAL SHUTTER SCANNED, STACKED IMAGE SENSOR CAPABLE OF SIMULTANEOUS INTEGRATION OF ELECTRONS AND HOLES

摘要

Various embodiments of the present technology may comprise methods and apparatus for an image sensor capable of simultaneous integration of electrons and holes. According to an exemplary embodiment, the image sensor comprises a backside-illuminated hybrid bonded stacked chip image senor comprising a pixel circuit array, and each pixel circuit comprising a charge storage capacitor oriented in a vertical direction in a deep trench isolation region. Both the electrons and holes are integrated (collected) using a global shutter operation, and the charge storage capacitor is used for storing a signal generated by the holes.
