Hello, I'm using Pyralin 2555 (1:1), ~3um thick, as a dielectric thin film. After photolitogrphy and development, I want to remove the photoresist (AZ2020) with Acetone, but the Pyralin is peeling off my substrate as well (it is not cured yet). Can anyone recommend me something about that? Thanks a lot, Yair Gannot, Process Engineer Wolfson Microelectronics Research Center TECHNION - ISRAEL INSTITUTE OF TECHNOLOGY Technion City, Haifa 3200, Israel Tel- +972-4-8293291
