Collaboration Overview
National University Corporation Saga University (headquartered in Honjo, Saga City, Saga Prefecture; Hiroaki Kodama, President; hereinafter "Saga University") and ITOCHU Techno-Solutions Corporation (headquartered in Minato-ku, Tokyo; Tatsushi Shingu, President and CEO; hereinafter "CTC") will start collaboration on research aimed at practical utility of diamond semiconductors*1, which are gaining attention as next-generation ultra-high-performance semiconductors.
Diamond semiconductors are expected to be applied to high-performance servers, high-performance communication devices, electric vehicles, and quantum computers as a technology that can achieve high energy efficiency. Saga University and CTC will accelerate practical use of diamond semiconductors, aiming to solve already troubling social issues such as energy issues to realize a digital society.
Saga University has been at the global forefront in research on diamond semiconductors, a.k.a. ultimate semiconductors.
CTC has worked on many IT solution projects to date. We have decided to collaborate with the university to get involved in the development stage of diamond semiconductor research, aiming to deepen our engagement in realizing a digital society (where both economic development and solving societal challenges are pursued) and to provide more effective services to this end.
In recent years, the widespread use of generative AI has increased power demand, posing challenges like the difficulty in achieving carbon neutrality due to increased CO2 emissions. We believe that improving energy efficiency by reducing power loss and heat generation in the power supply chain will contribute to solving such social challenges.
Collaboration Plan
Saga University will receive support for research on diamond semiconductors from CTC through commissioning contracts and will provide relevant technological information to CTC.
CTC plans to seek participants in this collaboration, standardize specifications, and establish frameworks for mass production, and aim for early utilization of the semiconductors to solve social issues. Additionally, CTC will support global rollout by working together with the ITOCHU Group.
Glossary
- *1 Diamond semiconductor Diamond semiconductors have approximately five times the bandgap energy of silicon semiconductors, which are currently widely used. If practically used, they could handle nearly 50,000 times more electricity than silicon as high-output and high-efficiency power semiconductors. Moreover, application of diamond semiconductors toward space communications and memory elements for quantum computers are also considered. Saga University possesses unique doping technology for diamond semiconductors, and has continuously achieved cutting-edge results such as output power of 875 MW/cm².
