Testing of semiconductor components under cryogenic conditions

As a link between research and industrial application, the Fraunhofer EMFT in Munich is dedicated to the characterization of electronic semiconductor components such as transistors or memory components at extremely low temperatures and under cryogenic conditions. Through these investigations, we evaluate the performance and reliability of these components under extreme conditions and create the basis for their integration into new technologies.
