Hi All, I need to deposit a photoresist of thickness about 5um, and pattern it in order to relize structures of lateral sizes 4x1000um. I tried using AZ9260 photoresist, but i had adhesion problems after development step. I used HMDS as adhesion promoter. I also tried to use a O2 plasma before photoresist spinning, but it did not helped. Any suggestions to improve photoresist adhesion ? Best regards, Andrea
