Comment on A home-made lithographically-fabricated integrated circuitComments−olskool8yIf he could get feature size down to 10 microns someone might have a shot at making a microprocessor.−AstralStorm8yAt that scale his hacked together (amazingly cheap) optical lithography equipment will not serve. (See how well it did with 1um lines. That is the main problem.)

Just for fun :) a B5000 maybe
