NMP (1-Methyl-2-pyrrolidon) is a powerful stripper due to its physical properties: NMP yields a low vapour pressure (no striation formation), strongly dissolves organic impurities as well as resists, keeps the removed resist in solution, and can be heated up to 80°C due to its high boiling point. However, since NMP is classified as toxic and teratogenic, a recommended alternative is DMSO.
