Not a CPU, but we made a complete and working SAW filter at university. We did everything from design to coating the wafers, lithography to ultimately bonding, housing and testing. I still have the thing somewhere.
Of course we depended on some machines, raw materials and especially a mono crystalline silicon wafer.
I think it is notable, that we did not really depend on an existing computer. Of course a SAW filter is simple, but the 6502 was still made with a similar technique. So if the material science is up to par again a microprocessor is a smaller step than one might think.
