The core competences are an indicator for the specific technological know-how of the Fraunhofer Institute for Electronic Nano Systems. The excellence of Fraunhofer ENAS is based on a broad variety of technologies and methodes for smart systems integration.

The three core competences "Silicon Based Technologies for Micro and Nano Systems", "Polymer Based Technologies for Micro and Nano Systems" and "Printing Technologies for Functional Layers and Components" are the technological basis for the development of components of micro and nano systems. "Interconnect Technologies" and "System Integration Technologies" are so-called cross-sectional technologies of smart systems integration. "Design and Test of Components and Systems" as well as "Reliability of Components and Systems" support the other technologies.
