Satish,

I know this problem. You have CxFy-polymer on top of resist and the ion
bombardment in RIE-chamber makes the film harder - so Aceton or what
ever you use - doesn't help.

You can try: O2-plasma first to remove this polymer film then Aceton/IPA.
If not: order cleaning agent Pine Alpha from Arakawachem Japan. It works.

good luck
