Hello, everybody, I need photoresist which could produce steep sidewall after developing. And I also need a 5-7 microns film thickness. Does anybody use Futurrex positive photoresist before? If so, please give me some advices about this photoresist, especially about the method to obtain the steep sidewall. Thank you.
