Hello Everyone,

As for poly-Si etching our never-ending problem came across again:



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?
