Abstract:
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 sensor 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 generated and integrated (collected) in the pixel simultaneously, and the charge storage capacitor is used for storing the signal generated by holes in the high light level illuminated pixels.

Claim (Index 12):
A solid-state stacked chip image sensor, comprising:\n an array of pixel circuits, each pixel circuit comprising:\n a photodiode; \n a floating body region; \n a capacitor connected to the floating body region and a ground potential; \n a charge overflow structure comprising a drain connected to the photodiode and configured to:\n divert charge having a first polarity from the photodiode to the drain; and \n divert a corresponding charge of opposite polarity to the capacitor after the photodiode has reached a predetermined charge threshold; \n \n a first readout circuit connected to:\n a floating diffusion region; and \n the photodiode through a charge transferring device; \n wherein the first readout circuit is configured to output an electron-generated voltage; and \n \n a second readout circuit connected to the capacitor and configured to output a hole-generated voltage; \n wherein each pixel circuit is formed across a plurality of chips.
