[Abstract]
CMOS image sensors (CIS) have witnessed tremendous technology advancement with wide adoption to the markets, with advantages of the ultra-low power and camera-on-chip integration. Short wave infrared (SWIR) imaging does not benefit from the development of these CIS technologies, because silicon does not generate photo-carriers with the light wavelength longer than about 1μm. By monolithically integrating quantum-dot (QD) photodiode on top of the fully processed CMOS readout IC (ROIC), low-cost, high-resolution SWIR image sensors were developed. Integration of QD with silicon readout ROIC allows access to SWIR imaging in applications that could previously not even consider this modality [1]. Furthermore, QD sensors show already stateof-the-art figures of merit, such as sub-2-μm pixel pitch and multimegapixel resolution [2-3]. This presentation briefly introduce QD image sensors, share basic characteristics and demonstrating an interesting application example.
