Abstract
A vertically-integrated image sensor includes a sensor wafer connected to a support circuit wafer. Each pixel region on the sensor wafer includes a photodetector, a charge-to-voltage conversion mechanism, a transfer mechanism for transferring charge from the photodetector to the charge-to-voltage conversion mechanism, and a reset mechanism for discharging the charge-to-voltage conversion mechanism. The support circuit wafer includes an amplifier and other support circuitry for each pixel region on the sensor wafer. An inter-wafer connector directly connects each charge-to-voltage mechanism on the sensor wafer to a respective gate to an amplifier on the support circuit wafer.
