How would you do that if there's like 60 layers of metal conductors over the silicon substrate?

Not sure if regular tomography would work, but this has been done at high enough resolution with some fancier techniques (ptychography): https://www.nature.com/articles/s41586-024-07615-6

I would imagine this is of decent interest to people reverse engineering chip designs, or doing failure analysis, so it’s possible someone might actually be trying this at scale.

You can destructively deprocess dies, removing a layer at a time and imaging at each layer. 20ish years ago you could still do this with a polishing wheel and a fine slurry; don’t know if that’s still viable.

It’s like taking a picture of someone’s house to determine their current medical diagnosis.

Garbage in, it’ Herpes.

Could have just said to determine where all the pipes are but you know, you could go all the way to herpes I suppose… :)
