Advancements in Large-Diameter Diamond Substrates Transforming Technology
Advancements in Diamond Substrate Technology
The innovative realm of diamond semiconductor technology is rapidly evolving, with Orbray leading the charge in the production of self-standing single-crystal (111) diamond substrates. The company's recent development showcases the creation of substrates measuring 20mm square, a significant milestone in manufacturing large-diameter diamond substrates. Such advancements pave the way for enhanced diamond-based quantum devices and power electronics, essential for meeting growing demands in various industries.
Commercialization Plans
Orbray aims to commercialize its large (111) diamond substrates by 2026. This ambitious goal reflects the company's commitment to advancing diamond semiconductors into mainstream applications. The development of these substrates not only addresses current market needs but also facilitates the integration of n-type self-standing diamond substrates. The latter is crucial for expanding the functionality and viability of diamond semiconductor devices.
Improving Semiconductor Performance
Diamond semiconductors are recognized for their exceptional thermal conductivity, outstanding electrical insulation properties, and remarkable electric breakdown strength. These characteristics make them highly desirable for applications ranging from high-power electronics to quantum computing. In recent years, research has intensified efforts to enhance the quality and size of diamond substrates, responding to increasing industry demands.
The Challenges of Diamond Growth
Historically, the production of large-diameter (111) diamond substrates faced significant hurdles. Until recently, available (111) diamond substrates were limited to smaller sizes, about 3mm square. The growth of (111) diamond crystals often resulted in defects termed twin crystals, complicating the manufacture of large and thick single-crystal diamonds. Overcoming these challenges has been vital for the advancement of high-performance diamond semiconductor devices.
Recent Achievements in Diamond Technology
In a notable breakthrough, Orbray successfully developed a high-quality 2-inch diameter (100) self-standing diamond substrate, utilizing their proprietary efficient step-flow growth method. Building on this achievement, the company has made significant progress in crafting the (111) single-crystal diamond substrates. This latest accomplishment leads to the creation of flawless diamond substrates, free from twin defects, marking a new chapter in diamond substrate production.
Future of Diamond Semiconductors
The future of diamond semiconductors looks promising with ongoing research and development in this field. Orbray's advancements aim to solidify the place of diamond semiconductors in various applications, which include power electronics and innovative quantum devices. Their synthetic processes also open doors for new research avenues and applications across different technological sectors.
Upcoming Conferences and Publications
The Japan Society of Applied Physics (JSAP) Spring Meeting and the International Conference on New Diamond and Nano Carbons are set to showcase groundbreaking research on diamond growth technologies. Seminars will highlight topics such as large-diameter (111)-plane diamond free-standing growth and the success of heteroepitaxial diamond on sapphire substrates. These conferences will provide an excellent platform for researchers and industry professionals to exchange ideas and explore the vast potential of diamond technologies.
