Not so much my field but I'd say a precondition would be that you can
produce a digitalised photographic (/holographic) representation of the
chip you hold in your hands. To analyse multilayered chips you would
grind them down in the process.
Or maybe you can image them in some kind of MRI...? Then you could at
least match your chip against the image of a prototype. Can a
microprocessor survive the MRI process? Are MRI resolutions high enough
to make the structures visible, at least for past generation chips? Are
the materials in the processor suitable to produce a clear image?
At least MRIs are getting more and more common. Maybe someone on the
list has experience in working with one.
Just a funny idea.
