I am interested in the Plasma desmear process. I have been reading alot
about this type of desmear technique and dont quite understand the
variables involved.
>From what I understand there is a combination of three gasses that
combine to create the "plasma" state ( the most common oxygen, nitrogen
and tetraflouromethane).
How are these gasses controlled and what effects do the ratio of the
gasses effect the etchrate?
