Fraunhofer Institute for Integrated Systems and Device Technology IISB

Fraunhofer I ISB conducts appl ied research and development in the f ie ld of

e lectronic systems for appl icat ion in, e.g. , e lectr ic mobi l i ty , aerospace, Indus-

try 4.0, power gr ids, or energy technology. In this connect ion, the inst i tute

uniquely covers the ent i re value chain from basic mater ia ls to ent i re power

e lectronic systems.

Semiconductors and Power Electronics

With its two business areas, semiconductors and power electronics, the IISB provides innova-

tion and solutions in materials development, semiconductor technology and manufacturing,

electron devices, packaging and modules, vehicle power electronics, energy electronics, and

energy supply systems. This is supplemented by broad activities in test and reliability, simulation,

characterization, and metrology. In addition to silicon technology, the IISB has a strong focus on

wide-bandgap semiconductors, especially silicon carbide (SiC). For SiC, the institute offers a com-

plete technology backbone, including materials science, devices, modules, and their integration

in highly efficient power electronic systems.

The headquarters of the IISB is located in Erlangen. The institute has branches in Nuremberg,

Freiberg, and Chemnitz. As one of the institutes of the Fraunhofer-Gesellschaft, the IISB does

contract research for industry and public authorities. It closely cooperates with Friedrich-

Alexander-Universität Erlangen-Nürnberg (FAU), with its Chair of Electron Devices (LEB) and its

Chair of Energy Electronics (LEE) being held by the directors of the IISB. The IISB has more than

250 employees plus numerous students working as research assistants. It is a member of Energie

Campus Nürnberg (EnCN) and Leistungszentrum Elektroniksysteme (LZE).

The IISB is equipped with high-class laboratories, such as a test center for electric cars and an

application center for DC grid technology. The IISB institute building itself serves as a research

and demonstration platform for advanced energy technologies to be used in industrial pro-

duction environments, linking electrical energy and non-electrical forms of energy by providing

the necessary interfaces. Together with the FAU, the institute runs 1500m2 of cleanroom area for

semiconductor technology on silicon and silicon carbide. The IISB operates the π-Fab, an electron

device prototype fabrication, which comprises a continuous silicon CMOS and silicon carbide

processing line in an industry-compatible environment. π-Fab supports its customers with specific

processing steps as well as with the fabrication of customized electron devices.

Finally, the IISB is a competent and strategic partner for national and international industry. Its

main objective is to provide excellent research to its industrial partners and to set technological

benchmarks as one of the leading research institutions in electronic systems.
