Thin-film technology (DST) has long mastered the high-precision application of very thin layers of various materials. So far, however, this technology has been closed to most users due to high investments in process development and production facilities. Sensor technology Wiedemann change that for the sensors now.

The processes for producing the thinnest layers are also the foundations of semiconductor manufacturing. Nevertheless, the potential of thin-film technology is far from being exploited. Further applications are conceivable primarily in sensor technology. Thin films are sensitive and reproducible on forces, deformation, temperature, light, chemical substances, etc. With a suitable design, the detection of magnetic fields and electric currents, with a spatial resolution of a few microns but is possible.

Nickel, chromium, copper, SiO2, TiON, and NiCr are just some of the materials that allow layers up to 1,5 μm thick to be adhered to any smooth surface. Structuring from a width of 10 μm is possible. One of the hardly used options of the DST is the direct application to application-specific deformation elements. For example, layers on 50 μm thin sheets have already enabled a new method for magnetic position measurement.
