Target Company Overview

Coral Capital has recently invested 140 million yen in a seed funding round for Okuma Diamond Device, a company focused on developing diamond semiconductors. This funding round also saw participation from GLOBIS CAPITAL PARTNERS, which has recently raised a significant 72.7 billion yen fund. This marks GLOBIS's first investment in a seed-stage deep tech startup, illustrating a growing interest in advanced technology ventures.

Despite being an unfamiliar concept to many, diamond semiconductors have the potential to revolutionize various industries, particularly in ultra-high-speed communication infrastructure, electric vehicles, and environmental resilience devices.

Industry Overview in Japan

The semiconductor industry in Japan is categorized into various domains, with power semiconductors being one of the significant segments. As of 2022, the power semiconductor market in Japan is valued at approximately 2.5 trillion yen, projected to surpass 13 trillion yen by 2035. Japanese companies like Mitsubishi Electric, Fuji Electric, Toshiba, and ROHM continue to hold significant global market share within this sector.

Power semiconductors, which differ from standard silicon semiconductors used in CPUs and GPUs, are specifically designed to handle high voltage and current, thus playing a crucial role in energy-efficient technologies across diverse sectors. They are essential for applications such as electric vehicles and infrastructure communication systems, proving to be a critical component in today’s technology landscape.

Recently, there has been a push for the revival of Japan's semiconductor industry, particularly by companies like Toyota and Sony through initiatives like Rapidus, which aims for a renewed presence in the global semiconductor arena. Power semiconductors, characterized by unique manufacturing processes and high customization needs, have thus been a key focus area for Japanese manufacturers.

Amid shifts in manufacturing technologies, innovations in semiconductor materials continue. Alternatives to silicon, such as Silicon Carbide (SiC) and Gallium Nitride (GaN), have started gaining traction, yet diamond materials are garnering attention for their superior properties in power management, thermal conductivity, and overall efficiency.

Rationale Behind the Deal

The primary reason behind Coral Capital's investment in Okuma Diamond Device stems from the significant business potential that diamond semiconductors present for next-generation technologies. With applications ranging from ultra-fast communication frameworks like 5G and beyond to energy-efficient solutions for electric vehicles, the startup is poised to lead this technological evolution.

Additionally, there exists an avenue for early monetization through various applications such as neutron detectors, satellite communications, and decommissioning projects for nuclear reactors. This dual-pronged approach, combining long-term technological potential with near-term revenue opportunities, made Okuma an attractive investment opportunity for Coral Capital.
