The Fraunhofer Society operates 76 institutes and research facilities in Germany and is the world's leading organization for application-oriented research. Around 30,000 employees work on an annual research volume of 2.9 billion euros.
The Fraunhofer Institute for Silicon Technology ISIT is part of the Fraunhofer Society and works with approximately 180 employees at the locations Itzehoe and Kiel in a leading position with industry and research on a national and international level.
Our scientists develop power electronic components and silicon-based microsystems. The »Power Electronics« department focuses on developing advanced active and passive power semiconductor components based on silicon and gallium nitride. We also integrate them into power electronic systems and develop battery storage and high-performance storage systems.Our GaN-based power devices focus on MOSFET Transistors with vertical current flow and High-Electron-Mobility Transistors (HEMTs) with lateral current flow. The goal of this position is to develop, process and characterize vertical trench-MOSFETs and diodes based on GaN-on-silicon (GaN-on-Si) substrates. The devices will be evaluated in traction inverters and the investigation of their failure mechanisms will conclude the activity. The position is to be filled immediately.
