Fraunhofer Institute for Electronic Microsystems and Solid State Technologies EMFTAs 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. 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.
