Noone really cares about used-up silicon. My uncle works at a major
company that builds semiconductor factories (A meta-semiconductor
factory?), the name of whic escapes me. It is the major one, though.
Anyway, he has an bad wafer, of Pentium chips.
By the way, is it theoretically possible to make an IC with only
a prototype IC and an arbitrary amount of machinery?
