The brilliant think about Chuck (not Charles) is that he designs the next
generation CPU using a computer built with the previous one. The chip is
actully fabricated in a foundry, but all the rest is self-made!

Hmm you need silicon wafers...an furnace were you deposit funny things
like arsenic or boron...an Aluminum sputterer...probably the litography is
not really the big problem here :)
