Hi everybody, I'm performing lift off to pattern SiO2 on a gold thin film on Pyrex substrate. My process will be: Remover 1165 bath (overnight) Remover 1165 bath + ultrasounds (some minutes?) Isopropanol bath? (how long?) 2 Rinses Spin Rinser Dryer Do you agree? Do you think I should do the isopropanol bath? for how long? If I well remember ISP breaks PMMA... what about pyrex (glass)? Thanks a lot, SM.
