The NASA Glenn Microsystems Fabrication Laboratory (MFL, located in Building 77) is a vertically integrated silicon carbide (SiC) semiconductor research and development facility dedicated to design, fabrication, and testing integrated circuit electronics and sensors uniquely durable to extreme environments. To date MFL is the only laboratory in the world that has fabricated and tested packaged semiconductor integrated circuits operating at 500 °C for over a year. This laboratory is available for assisting external partners in the design and prototyping of developmental extreme environment SiC sensors and electronics under mutual agreement negotiated by the NASA Glenn Technology Transfer Office
