I just quit a gig at a semiconductor supplier that makes EUV light. Keep in mind this is just one major component in the chain: - EUV comes from a plasma of metal created in a vacuum chamber. - the plasma is created by concentrating a beam of light on a tiny pellet of molten metal - that beam of light is a 25kw laser, which is borderline weapons-grade. To the point that countries hesitate to even allow it to be imported. - the laser must be pulsed precisely to vaporize the metal as its flying through the chamber - residue from the metal vapor quickly builds up and deteriorates the process getting this stuff to work requires armies of engineers and scientists. the machines themselves are the size of a tour bus.
