Hello Edward. Which kind of plasma treatments are suitable for SU1828? Or is it not changeable resist by resist? I use SU1828 for first lithography and TI35 for second. I think i will treat SU1828 but i am not sure for the ambient. I can apply O2 plasma, CHF3, SF6, CCl2 with RIE also. Which one is suitable do you think? Thank you for your help. Best Regards.
