Diamond is considered to be a material for next-generation power semiconductor devices due to high thermal conductivity and breakdown voltage. In this research, triple-gate metal-oxide-semiconductor field-effect transistor (MOSFET) device was fabricated using a hydrogenated diamond (H-diamond) substrate. In device fabrication, Samco open-load Reactive Ion Etching (RIE) system at National Institute for Materials Science (NIMS) was used for diamond plasma etching to form a diamond mesa structure.
