Power Diamond Systems and Toray Research Initiate Joint Research on Next-Gen Diamond Semiconductor Devices

Joint Research to Accelerate Diamond Semiconductor Technology

Power Diamond Systems (PDS), a Tokyo-based startup specializing in diamond semiconductor devices, and Toray Research Center (TRC), also located in Tokyo, have formalized a partnership to propel the development of next-generation diamond semiconductor devices. By leveraging advanced material analysis and interface characterization techniques, the project aims to visualize the microstructure, impurity distribution, and interface characteristics of diamond semiconductors with high precision. This effort is geared towards building a robust evaluation framework that enhances both device performance and reliability.

Background of the Initiative

The demand for enhanced efficiency and miniaturization in electric vehicles, renewable energy, and industrial power control systems underscores the necessity for breakthroughs in next-generation power semiconductor devices. Among various materials, diamond stands out for its remarkable thermal conductivity and wide bandgap, presenting an unmatched potential compared to traditional power semiconductor materials. However, to realize its practical application, a comprehensive understanding of how microstructures, interface conditions, impurities, and defects impact device performance and reliability needs to be established. Thus, a technological foundation capable of high-precision evaluation and analysis is critical for this segment.

Objectives of the Joint Research

This collaboration will merge TRC's high-precision material analysis techniques with PDS's expertise in diamond power semiconductor device design and processing technology. The research aims to methodically elucidate the correlations between material characteristics, microstructure, interface conditions, and their effects on device performance and reliability. TRC's insights derived from detailed analyses at the nanoscale will be rapidly fed back into PDS's material and process development, creating an advanced material development cycle that intertwines analysis and development. Consequently, this initiative seeks to enhance the performance and reliability of diamond power semiconductors and expedite their practical application and mass production.

Comments from Leadership

Tatsuya Fujishima, CEO of Power Diamond Systems, emphasized the company's commitment since its establishment in August 2022 to realize next-generation power electronics through diamond semiconductor research and development. In addition to advancing device structures and processing technologies, enhancing performance and reliability with a focus on social implementation remains a key area of research.
