Hello All, I was wondering whether anyone can help me. I am currently processing 260micron SU8-2100 layers on Silicon substrates. I have tried the suggested procedure by microchem but did not get the results I wanted. I have also gotten procedures from other groups in the literature but many are quite different to each other. I am especially concerned about the exposure times which varies a lot from different groups. Has anyone had experience in processing layers this thick with good results and could share their procedure or experiences. Any input will be greatly appreciated. Thank you.
