Mission & Goals

In the last decades the rapid development in the area of electronic devices was mainly determined by the continuing miniaturization of the structure sizes. This is accompanied by the appearance of novel phenomena, caused by the ever increasing electric field strengths and emergence of quantization effects. These effects have to be understood, investigated and modeled. At the same time, the limits of scaling are foreseeable. Therefore there is a need for alternative solutions, like integrated optical and magnetic devices, which enable a further improvement in the performance of electronic systems with respect to speed, low power consumption, cost reduction. 

Additionally, the technological advances achieved in micro- and nanoelectronics can also be used for devices with extended and completely different functionalities. Thereby, for components in optoelectronics, bioelectronics, power electronics and microsystems ever better performance data can be obtained. To achieve this, a corresponding basic research is necessary. With respect to the complex relations between process, device and system, the best solutions are only obtained if the complete chain of process, device, circuit and system parameters is regarded synoptically. For this, we combine our expertise and competencies in semiconductor technology, physical device understanding and modeling, technology related circuit design and methodical design automation, to develop improved or completely new solutions.

A further area of growing importance are micro-structured semiconductor devices for power electronics, that have a key function in custom designed assemblies with lower power, higher immunity to disturbances and higher reliability under often harsh operating conditions. To obtain these goals, powerful simulation platforms have to be developed. They enable to perform detailed and precise virtual experiments and tests by simulation also under conditions, which are outside of the secure operation range of the devices close to the occurrence of damage.
