Yeah fair. Pretty much every part of the process is bonkers. Just the light sources draw something like 1 megawatt and weigh over 100 tons (for extreme ultraviolet). EUV gets absorbed by everything including air, which is bad, but the light source requires plasma so somehow you need both the plasma and vacuum in the same machine without a window or whatever to separate them. Then the features on the chip are so small that random variance in the spatial distribution of landing photons causes defects. And that's just the light, it's amazing anyone can make the process work at all. |
