Dear Colleagues, I'm searching for information on any and all resists (or similar photopatternable materials) that can be deposited and patterned with fairly vertical sidewalls in a layer at least 20-25 microns thick. I have no particular preference for negative or positive-working. The only thing I'm familiar with is SU-8, but there must be quite a few others. Product names, manufacturers, and phone numbers would be greatly appreciated. Sincerely, Adam Cohen USC
