Main areas of responsibility in the research activities of the “Microsystem Electronics” working group at the Professorship of Electronical Devices of Micro and Nano Technique are the development of integrated electronic micro systems and electronic micro and nano devices and the solution of customer-oriented problems.

The current research projects are:

  • In the BMBF project “ModElan” a module platform for customized solutions of compact electrical drives are investigated
  • Smart-power applications realized by a trench isolation, which contains the design of integrated high-voltage electronics and characterization of high-voltage isolation structures to optimize the production technology
  • Research and development of applications for energy-efficient sensor systems and investigation of weak-inversion circuit techniques are the content of the “nano system integration network of excellence – application of nano technologies for energyefficient sensor systems”
  • The DFG-Research Unit 1713 “Sensoric Micro- and Nanosystems” investigates at the integration of different technologies and functionalities in a micro system to transmit signals and information and to interact with the environment
  • “SmartFilter – intelligent filter monitoring system” is a further BMBF project. The development of a system for accurate monitoring of the filter contamination level and the temperature is the project objective.
  • Design of intellectual properties for the MEMS-technologies, currently for a 1μm-CMOS-technology with monolithic integrated pressure sensors
  • Development of next generation electrical drive systems, e.g. electric motors with high efficiency and smart power control concepts
  • Development of customized measuring strategies and characterization of In-Die parameter variations for semiconductor structures in nanotechnologies
  • Electrical and physical design and characterization of analog and mixed-signal standard circuits for the CMOS-process
  • Creation of simulation models for SOI-devices
  • Investigation and modeling of isolation structures for high-voltage ICs
