Abstract:
An exemplary stacked photodetector assembly includes a first wafer and a second wafer bonded to the first wafer. The first wafer includes a SPAD and has a thickness T 1  configured to minimize absorption by the first wafer of photons included in light incident upon the first wafer while the SPAD is in a disarmed state. The second wafer has a thickness T 2  configured to provide structural support for the first wafer. The stacked photodetector assembly includes a fast gating circuit electrically coupled to the SPAD and configured to arm and disarm the SPAD.

Claim (Index 11):
The stacked photodetector assembly of  claim 1 , further comprising:\n an additional voltage source connected to an input node of the SPAD and configured to supply a reverse bias voltage at the input node, the reverse bias voltage having a magnitude that is equal to or less than the breakdown voltage of the SPAD, wherein the voltage source is configured to selectively connect to the capacitor to charge the capacitor with the bias voltage, the bias voltage being an excess bias voltage that has a magnitude that is less than the magnitude of the reverse bias voltage supplied by the additional voltage source; and a switch configuration configured to put the SPAD into the armed state by connecting the capacitor to an output node of the SPAD while the capacitor is charged with the excess bias voltage and while the capacitor is disconnected from the voltage source; wherein, when the capacitor is connected to the SPAD, the capacitor supplies the excess bias voltage to the SPAD such that a voltage across the SPAD is greater than the breakdown voltage.
