Hi,

If you have large areas of SU-8 a thermal shock - heat the wafer and cool in
water - might do it. Otherwise think about a SU-8 which has a bad adhesion to
your substrate (e.g. HMDS priming prior to spinning or sacrificial photoresist).
As already mentioned, etching SU-8 will be difficult.

Hi Jeff.
The OmniCoat will help removal of the SU-8. You can try to apply it before SU-8.
Good luck

Does anyone have some experience to completely remove SU8 after development?
I tried PG Remover and it didn't work well. And also plasma cleaning
under oxygen, still not working.
