"The understanding of complex root cause-and-effect chains and the creative application of emerging technologies safeguards the competitive advantage for Bosch and enables reliable and innovative "technology for life"."
Together with my team at Bosch Research and the colleagues in the business unit Automotive Electronics development, I work on a better understanding of our future microsystems and their production processes. With our technology, we can demonstrate high-precision micro- and nanostructures from thin films down to the monolayer level in the research cleanroom. This level of precision is mandatory for the reliable operation of today's smart, high-performance, optical and mechanical microsystems.

Interview with Christoph Schelling, Dr.
Senior Expert for MEMS Technology
Please tell us what fascinates you most about research.
The creative freedom to bring in and drive one's own ideas thereby shaping a small part of the Bosch future adds that special extra spice.
What makes research done at Bosch so special?
The scientific, interdisciplinary work in a creative team of highly qualified, brilliant minds on demanding and challenging topics is a constant source of motivation and inspiration. The impossible suddenly becomes possible in this environment.
What research topics are you currently working on at Bosch?
I ponder how we can further improve our microsystems in order to make them even more reliable and precise in future. For example, I look into the question on how to produce the structures even more precisely. Recently, we have been able to prove that the production tolerances of the structures can be reduced down to the level of a few hundred atoms. This is a quantum leap in process technology!
What are the biggest scientific challenges in your field of research?
Microsystems are an ever recurring challenge. You think that you have understood a microsystem thoroughly, but every now and then you will experience a surprise. The understanding of aging phenomena and root-cause-and-effect chains is not yet as thorough as in the highly standardized microelectronics, for example. Degradation requires multidomain knowledge from several disciplines (mechanics, electrostatics, chemistry, ...).
How do the results of your research become part of solutions "Invented for life"?
I work closely together with colleagues from the business unit Automotive Electronics in order to leverage our research results early and directly into products. Those products support many aspects of our daily lives, from safety to comfort.
