Polymide?
You mean polyamide or polymers or what?

Hot oxygen or fluorine will pretty nearly certainly work but probably won't be very practical.
What are you trying to do?

Sulphuric acid might do the job, but it may damage other things too.

An alkaline etch might work, but it is more likely to damage the silicon.
Have you tried sodium hydroxide?
