"TSMC's pixel-level stacking technology enables higher resolution, HDR and Global shutters that are imperatives in fully autonomous vehicles. Our high QE(Quantum Efficiency) NIR technology enhances vehicle night vision. NIR+ at visible wavelength and NIR+ Gen2 at longer wavelength are being added to the portfolio, to make 940nm/1550nm Lidar sensor feasible."
Interesting news. Any information on the technology they are using?

ReplyDeleteWhat about dark current? Lag? Hot pixels? ...?
DeleteI did read something about SiGe, but I did not think it was commercially viable.
It was new to me that SiGe is another aproach for detection in the >1200nm range. Are there any other technology approaches for the >1200nm range other than
Delete- SiGe
- InGaAs
- other compound Semiconductors like HgCdDe, InSb...
- CQD and other 'quantum dot' approaches
- Graphene
- Schottky Diodes
Nanowires are another approach which also limits dark current
ReplyDeleteI thought the sensor that used graphene was not really using graphene to convert light, it was using CQD for the bulk light conversion and graphene as the top layer contact.
