We have had success with vacuum cavitational streaming in removing some
stubborn resists.
Drop me an email at hyperflo@hyperflo.com if you want to discuss further or

Subject: [mems-talk] hardbaked photoresist...
I have a problem in that I cannot get hardbaked PR (SPR-220) of my
surfaces, both gold and Si.
With the gold sitting on TiW, piranha is not really a feasible solution.
I have tried long o2 plasma ashes and overnight baths in heated prs-3000
with little success.
Any other solutions I can try?
