BSI is very simple compared to what they are proposing here. BSI illumination does not require that any features are actually built into the backside. It basically just requires that the backside be polished very nicely. Here we are talking about building elements on the backside and then connecting them to the front side. It is much trickier.

That's not entirely true. BSI always had some metallization on the backside for aperture, power and packaging. For example, see this: https://image-sensors-world.blogspot.com/2018/03/techinsights-publishes-samsung-09um.html https://image-sensors-world.blogspot.com/2018/03/techinsight... Perhaps what they're proposing is more sophisticated, but definitely not something entirely new.
