How to "open" a microchip and what's inside?
I've got to add that this is pretty much how Intel's x86 processors were reverse engineered [1] for use in Soviet IBM PC clones like Poisk [2]. Most resources on the Web talk about clones of CPUs up to and including the 80286 but I am told there was at least one successful attempt at cloning an earlier version of the 80386. The smaller sub-1 µm process used by Intel for later 80386 and 80486 units proved too much, however.[1] http://www.cpu-world.com/info/exUSSR-chips.html[2] http://www.oldcomputermuseum.com/poisk.html
