I found this interesting:


In that article, Sony described a new high resolution SWIR sensor using Copper wiring to improve signal. Apparently, SWIR are becoming more popular.

This is the quote:
"Sony Semiconductor Solutions Corporation
We developed a back-illuminated InGaAs image sensor with 1280 x 1040 pixels at 5-um pitch by using Cu-Cu hybridization connecting different materials, a III-V InGaAs/InP of photodiode array, and a silicon readout integrated circuit (ROIC). A prototype device showed high sensitivity at visible to SWIR wavelengths and low dark current."

That is very cool. But obviously experimental, so may be a while...
