Hello original poster! I can't find the original email about this, but if I remember properly, the poster wants to deposit onto un-crosslinked (unexposed SU-8). Something important to think about is what effect the brightly glowing source is going to have on your photosensitive substrate. I don't know if the source glows at the proper wavelength to expose SU-8, but I do know that it's bright enough that we don't look at it without a welding glass. At least, in an evaporator. I understand there's a glowing plasma in a sputterer, as well. But, I don't know how bright that is. Is your process going to get messed up if the SU-8 is exposed by the metal deposition method? What if it's only partially exposed? If so, you're probably going to have to do a few experiments to find a solution. Sincerely, Jesse Fowler
