And the clean environment as a whole. That's a massive investment and there are a million ways to mess that up.

wafers are the easy bit.
Hold on, if I had an electron microscope, can I just put in a decapped cheap large format photodiode under it, jack the beam current way up, and start etching trenches on it?
