For some years now, NMP has been classified as toxic to reproduction and the use of NMP has become more and more restricted. Now the EU has continued to restrict the use of NMP, so that after 09.05.2020, NMP can only be used if special precautions are taken.

Technic France, our current single supplier for NMP, has now decided to completely stop the production of the NMP.

We have many products in our portfolio that can replace NMP and many customers have already qualified alternatives in the past due to the increasingly problematic situation regarding NMP. DMSO, TechniStrip D350, NI555, P1316, P1331, MLO-07, Micro D2, AZ 100 Remover or the strippers from Intelligent-Fluids SH5 and SVD can be considered as alternative products.

We would be happy to supply you with samples of possible alternatives; it is best to briefly describe the process and the (substrate) materials involved so that we can explore the best alternatives together with you.

Available Purity Grades of NMP

We supply NMP in ULSI-quality as typically used in the fields of semiconductor processing and micro-electronics. The specifications of both qualities are listed in the technical data sheet below.

Typical Fields of Application of NMP

NMP is a powerful lift-off medium due to its physical properties: NMP yields a low vapour pressure (no striation formation), strongly solves organic impurities as well as resists, keeps solved particles in solution, and can be heated up to 80°C due to its high boiling point. For the same reasons, NMP (pure or diluted in H2O) gives a very well-suited stripper for photoresists processed under harsh conditions.

Substitute for NMP?

Due to the toxicity of NMP and its position of the SVHC-list (REACH), the long-term availability of NMP can not be guaranteed. Therefore, we strongly recommend to consider alternative substances.

For non cross-linked resist films the AZ® 100 Remover, DMSO or other common organic solvents cab be used as stripper. If the resist film is crosslinked (e. g. by high temperature steps > 140°C, during plasma processes such as dry etching, or during ion implantation), we recommend the NMP-free, nontoxic TechniStrip P1316 or TechniStrip NI555 as remover.
