http://sam.zeloof.xyz/first-ic/ http://sam.zeloof.xyz/first-ic/ This is one of the things where the details of the "booting civilization" situation matter a LOT. If you can find a Blu-ray player, it'd be much easier for you to make something like Breaking Taps did- no need for a projector or computer, you could even do this by hand using an optical relay. However it's VERY hard to make an appropriate UV laser[1], and it's very hard to make a photoresist that works in infrared where a CO2 laser is easy to make. In that case you have to use a projector. For a while I've wondered how feasible it would be to use an electron microscope to just ablate everything. Shockingly easy to make for such an excellent instrument. [1]: Ironically the easiest type of laser to make is a UV nitrogen laser, but it's extreme power and short (nanosecond) pulse time mean you can't use it for this: http://www.repairfaq.org/sam/lasercn2.htm#cn2cn20 http://www.repairfaq.org/sam/lasercn2.htm#cn2cn20
