They etch thin copper, then plate it back up afterwards. That's a
tricky process to do at home, I suspect.
However, by the time you need 4/4 or whatever, surely you're also
calling for tiny, plated-through vias and multi layers? There comes a
point when you just pay someone. I can't see me ever doing finer than
6/6 at home.
