Abstract

This paper reports on the state of the art of the Quanta Image Sensor (QIS) being developed by Dartmouth. The QIS is a photon-counting image sensor. Experimental 1Mpixel devices have been implemented in a modified backside-illuminated stacked CMOS image sensor process. Without the use of avalanche multiplicative gain, the sensors have achieved room temperature average read noise of 0.22e- rms (analog readout) permitting photon counting, and over 1000fps readout at under 20mW total power dissipation including pads (single-bit digital readout).
