What is the etch rate of SU-8 in O2 plasma?

Hi,

        May I add a question? I've tried to ash SU-8 with O2 plasma in
ICP/RIE system. But there is a film of residue on wafer. Have you seen
such problem?

system. OUr experience with oxygen and su8 shows it will ash but it is better if
you have not done the second bake. This has been done in an icp/rie system and
the etch rate is a little less than other negative working photoresists. Bob
