Hi, I'm looking for negative photo resist for 5 to 30 um processing. In this process the resolution is not important. The resist and developer should (if possible) be nontoxic. It would nice to have resist stripped in Ace or in some AZ developer. I know Japanese have resist called NFR015, but they doesn't seem to sell it to Europeans. I wonder what you might know about PR's or PR vendors? With Best Regards, Antti Peltonen Process Engineer Helsinki University of Technology
