Outline of Final Research Achievements

For the decommissioning of the Fukushima Daiichi Nuclear Power Plant in Japan, installation of robots has been promoted. However the electronics are mainly consist of conventional silicon integrated circuits, which is vulnerable to radiation. And then the electronics limits the operation time for the decommissioning. For the radiation hardened electronics, we need to apply other semiconductor with radiation hardness. 4H-SiC semiconductor is one of the candidates for such a material. In this research project, we promoted research and developments on 4H-SiC MOSFET devices and integrated circuits, research for high performance, and for harsh environment applications, under the international collaboration.
