The Center for Integrated Research of Future Electronics (CIRFE), established in October 2015, engages in leading-edge electronics research-including research in the untraversed area of devices with gallium nitride, carbon nano-tube, SiC and other post-silicon materials-while also cultivating top-notch human resources to lay the foundations of the future electronics industry. CIRFE is divided into seven sections, each staffed with instructors who serve as leading specialists in their field, and equipped with outstanding research infrastructure. The Center's fully integrated joint research and education system covers everything from basic scientific education on materials, measuring, devices, and applied systems through to the completion of student educational courses. Through research on energy-saving devices, an area in which very little experimentation has been carried out anywhere in the world, CIRFE strives to foster well-trained human resources who will lead the field of manufacturing in the twenty-first century.

Device Innovation Section
The Device Innovation Section aims to develop devices with new functions by establishing new crystal-growth methods and process development for cutting-edge electronics materials with a central focus on wide-bandgap semiconductors, such as gallium nitride and silicon carbide, and nanocarbon materials. A fully integrated research approach enables us to establish a unified process from crystal growth to device design, manufacturing, and assessment.
