Wow, no!
Laws are laws especially these sensitive issues must be obeyed in my opinion.
I would build a plasma etch system.

Where I just have been living for a long time laws are just there so that people can find ways around them, so yeah, besides potentially building a simple plasma etcher by using this magnetron sputter setup from Hackaday and running it in reverse, we might also try to find ways to buy those chemicals in diluted form and then turning it into a more concentrated form in our lab... hmm

Hello Everyone,
As for poly-Si etching our never-ending problem came across again:
http://sam.zeloof.xyz/second-ic/
https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32019R1148
He is probably not an European guy... And Europe aims to be on the map
in terms of scientific progress... Never mind, we need no amateurs. Just
spill a ton of public money onto our for-profit firms, they will solve
everything in the right way. < / rant >
The problem is nitric acid, that is visible outright. The n-dopant is
also likely no-go (I did not find explicitly, but knowing how the
legislators think, they may crap their pants on the word "phosphorus
compound"). Any idea on solving this?
Regards,
Ferenc

Hi
Yes. That's what I'm planning to do as well.
The idea just was to design a bit more compact stepper, which can also be
scaled up and sold for professional industrial environments, considering that
the furnace costs 3200 USD and I've got to get the cash back in :-)
Cheers,
lev
