The challenge and objective of our process engineering development work is to find the best ways of combining thin films using a variety of specialized techniques. Thanks to our combination of preparation methods and ana- lytical tools, we are well prepared to successfully handle the development challenges of our clients across the Fraunhofer IGB portfolio – whether in the medicine, pharmacy, chemistry, the environment or energy business area.
