<aside> 💡 Ookuma Diamond Devices Co., Ltd. is an innovative company established in 2022, with the aim of commercializing technologies cultivated through the Fukushima Daiichi Nuclear Power Plant decommissioning project. The company's core technology focuses on diamond semiconductors, specifically analog devices responsible for power control and frequency conversion.
Diamond stands out for its exceptional thermal conductivity, dielectric breakdown strength, relative permittivity, and carrier mobility. This unique combination gives Okuma Diamond Devices a forward-thinking advantage and strength in utilizing high power with high efficiency. This technology specializes in areas where "only diamond can provide solutions." For example, it can operate at high temperatures of 300°C and under radiation exposure of 3 MGy, enabling robust radiation-hardened devices for nuclear reactor decommissioning and space applications. Crucially, it eliminates the need for cooling devices, which are essential for existing semiconductors, thus allowing for miniaturization and weight reduction.
Furthermore, this technology aims to resolve the bottleneck of high-speed, high-capacity data communication in next-generation services such as autonomous driving, drones, IoT, blockchain, the metaverse and so on. Addressing the challenges of existing 5G's narrow coverage area and increasing power consumption, diamond semiconductors achieve both high output and high-frequency performance. They are considered "the only material that can be applied to base station deployment beyond 5G." Significant contributions are also anticipated in mobile phone base stations, inter-base station communication, satellite communication, and radar fields.
The company's business and vision are to contribute to solving Japan's decommissioning problems through technology and to commercialize the new technologies born from this endeavor. Specifically, their goal is to "establish a mass production technology platform for diamond semiconductors and become a pillar supporting the next-generation IT industry." They also possess a unique value chain and several fundamental patents, looking beyond devices for the Fukushima decommissioning project to future specific target markets. This alignment of unique technology and clear market needs suggests extremely high market potential. Moreover, strong collaborations with leading domestic research institutions such as Hokkaido University, AIST (National Institute of Advanced Industrial Science and Technology), NIMS (National Institute for Materials Science), and KEK (High Energy Accelerator Research Organization) further bolster their prospects. We wish Okuma Diamond Devices Corporation continued success. (AS)
