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 1):
A stacked pixel circuit formed on a first chip and a second chip, comprising:\n a photodetector configured to generate electron charge and hole charge in response to light; a charge overflow device connected to the photodetector and configured to divert the hole charge to a capacitor; a floating body node disposed between the photodetector and the capacitor; a first readout circuit connected to the photodetector and configured to output an electron charge-generated voltage; a floating diffusion node disposed between the photodetector and the first readout circuit; and a second readout circuit connected to the floating body node and configured to output a hole charge-generated voltage.
