Revolutionary Advances in Large-Diameter Diamond Substrate Production Technology by Orbray

Revolutionizing Diamond Technology: Orbray's Breakthrough

Orbray Co., Ltd., a prominent player in precision jewel parts and advanced manufacturing technologies, has achieved a significant milestone in the realm of diamond substrates. The company recently announced the development of the world’s largest self-standing single-crystal (111) diamond substrates, measuring an impressive 20mm on each side. This innovation is expected to set new milestones in the field of diamond-based quantum devices and high-performance power devices.

In the diamond semiconductor industry, there has been a surge in demand for larger and high-quality diamond substrates, primarily due to their unique properties that enhance device performance. Historically, the production of sizable (111) diamond substrates proved problematic due to the susceptibility of these crystals to defects during the growth process. Previously available options were limited to small (3mm square) substrates that did not meet the industry's increasing requirements.

Orbray's revolutionary production method, specifically the efficient step-flow growth technique, has opened doors to creating defect-free, large-diameter single-crystal diamond substrates. In previous press releases, such as one from September 2021, the company showcased its success in synthesizing high-quality 2-inch diameter (100) self-standing diamond substrates. This foundational success has paved the way for the current achievement of the 20mm square (111) substrate, free of twin defects, which are typically challenging to eliminate in the CVD growth process.

This advancement is not merely an engineering feat; it holds profound implications for the future of diamond semiconductors. Diamond devices, particularly those incorporating nitrogen-vacancy (NV) centers, are renowned for their applications in quantum computing and high-efficiency power electronics. The ability to produce larger, high-quality (111) substrates means a direct expansion of the applications for diamond semiconductors.

As Orbray aims to commercialize these large substrates by 2026, the market can expect a shift toward mainstream adoption of diamond semiconductor devices. This transition is crucial because the integration of n-type self-standing diamond substrates is imperative for the widespread implementation of diamond-based electronic devices. Recent partnerships and collaborations in cutting-edge research, such as those showcased at the Japan Society of Applied Physics Spring Meeting and the International Conference on New Diamond and Nano Carbons, further underline the interest and vitality surrounding this innovation.

Founded in 1939, Orbray has a rich history of blending traditional craftsmanship with modern innovations. The company’s ongoing research and development not only reflect its commitment to advancing diamond technology but also its pivotal role in the semiconductor landscape. With its headquarters in Tokyo, Japan, Orbray continues to be at the forefront of diamond manufacturing, leveraging expertise and advanced technologies to push boundaries.

In conclusion, Orbray’s progress in the mass production of high-quality, large-diameter single-crystal diamond substrates heralds a new era for semiconductor technology. As we look ahead, the implications of this innovation promises not only to enhance the capabilities of current devices but also to spur future advancements in numerous applications, including quantum computing and energy-efficient electronics.

For further information, industry stakeholders and enthusiasts can stay updated with Orbray’s upcoming research publications and commercial offerings, as the organization gears up for the commercialization phase in 2026.
