A comment on 5nm vs. 3nm. Parent comment
- 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.
