Tmah chemistry
WebA TMAH based positive photoresist developer such as OPD 262 or OPD 4262 is recommended. The develop time is dependent on the polyimide softbake, polyimide thickness, exposure dose and develop method. A spray puddle process should include a short dynamic spray time of 6-8 seconds to remove Spin Curve Durimide 116 WebNational Center for Biotechnology Information
