Since 2001 we supply a growing number of research institutes, start-ups and production facilities in the field of micro-structuring with photo resists, ancillaries, solvents, and etchants in semiconductor quality.

Beside our continuously growing product range, it's our utmost concern to assist you with related technical support, short lead times, and suited sales units.

Do you have any technical questions concerning your litho processes, or our products? Please do not hesitate to contact us!

Your Team MicroChemicals


This week (KW34) we were informed by the manufacturer Merck, whose distributor we are, that due to an ingredient (based on PFOS surfactants) the resists AZ 9260 and AZ 9245 are now no longer available and may no longer be placed on the market, according to which there are no salable stocks remaining.

You can find the official letter from the manufacturer together with an updated MSDS below. However, with the AZ 10 XT there exists a PFOS-free alternative, otherwise - to a large extent - identical to the AZ 9260, which should allow you to continue your previous processes with the same parameters and the same results.

We will gladly send you samples on request.
Please contact us: sales(at)microchemicals.de

Thank you for understanding!

Our new Strippers

Photoresist Stripper SVD and SH5

The strippers easily removes layers of photoresists (PR) from inorganic substrates such as silicon, glass and metals (e.g. copper). The smart intelligent fluids® (IF) mode of action is not based on aggressive dissolving processes as in the case of many conventional products. Instead, intelligent fluids® enable a gentle physical detaching even of persistent layers, without damaging the substrate surface.

The strippers works with highly dynamic phase structures in two steps:

● infiltration and fragmentation of the layer
● wrapping and removal of fragments

Negative-tone photoresists will be detached in larger fragments and can be filtered off. Positive-tone photoresists on the other hand will be incorporated
into the fluid.


● water-based
● pH neutral to the skin (pH: 5.5 – 6.5)
● non-toxic, non-flammable
● safe-to-handle
● dermatologically tested - “excellent”
● readily biodegradable
