Your Benefits

A particular R&D focus is application-specific device design and the development of new device architectures. Another important research topic is the development of new processes for advanced power devices at wafer level. For gallium nitride devices, ISIT is also developing front and backside contacting methods for bulk GaN wafers and GaN-on-Si wafers.

For system integration of passive devices, Fraunhofer ISIT offers the development of chip capacitors, precision resistors and inductors as well as corresponding chip-level circuits. At ISIT, the complete development chain from simulation and design to the development of single processes and complete process lines on 8" manufacturing equipment and numerous characterization tools is offered.
