TSMC Offers 1550nm Sensing Platform

TSMC publishes its LiDAR and HDR sensing automotive portfolio mentioning 1550nm NIR+ Gen2 imaging platform:

"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."

  1. Interesting news. Any information on the technology they are using?

    1. What about dark current? Lag? Hot pixels? ...?

      I did read something about SiGe, but I did not think it was commercially viable.

    2. 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
      - SiGe
      - InGaAs
      - other compound Semiconductors like HgCdDe, InSb...
      - CQD and other 'quantum dot' approaches
      - Graphene
      - Schottky Diodes

  3. Nanowires are another approach which also limits dark current

  4. I 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.
