Here are some detail. Hoping that this will be helpful.
Photoresist is being spin-coated on the Si (silicon) substrate and 800 nm of Al (aluminium) thin film was deposited on the photoresist. And the thin film just peel off then. Any suggestions to improve the adhesion of Al thin film on photoresist.
Waiting for replies,
Best Regards!!!

Maybe someon on here can help answer this better. I thought this was a thermal spray question. Is the substrate being cleaned and or etched? Is the alumium in a solution, spun and then vac baked?

RE: Issues in Al coating on photoresist
which deposition method do you use in order to deposite the aluminum thin film?, I can assume that this is not a thermal spray application, so try to clean the surface with a thiner or other meccanica media.
Best regards
