Element Six and Orbray accelerate wafer-scale single-crystal diamond for volume production
Synthetic diamond materials firm Element Six of Oxford, UK (E6, part of the De Beers Group) and Tokyo-based Orbray Co Ltd (which makes precision jewel parts, DC coreless motors, fiber-optic components, and medical devices) have announced the next phase of their partnership, building on a joint aim to deliver wafer-scale single-crystal diamond (WSC).
The firms have established a reproducible process for 3-inch WSC diamond, representing a significant step change in size, uniformity and manufacturability compared to conventional single-crystal (SC) diamond materials. Development of larger 4-inch substrates is underway.
In parallel, 2-inch wafers optimized for epitaxial applications are nearing finalization, while 2-inch wafer diamonds for thermal bonding applications are being prepared for volume production at E6’s chemical vapour deposition (CVD) facility in Gresham, Oregon.
Since establishing the partnership, E6 and Orbray’s efforts have focused on advancing wafer size alongside manufacturing maturity, aiming to accelerate broader adoption of WSC diamond across 6G wireless components, power and RF electronics, sensing, thermal management, and quantum technologies.
Together, these developments represent a transition from R&D to scalable implementation, with the collaboration between the companies now shifting focus on refining production processes to support operational ramp-up for volume manufacturing at industrial scale.
“Our partnership with Orbray was built on shared strengths in innovation, quality and technical expertise,” says E6’s CEO Siobhán Duffy. “The progress we are making together shows how those core competencies translate into tangible delivery, as we move closer to pioneering wafer-scale single-crystal diamond at the quality and volumes our industrial customers need,” she adds.
“The milestones achieved so far represent meaningful steps in the journey we started, together with Element Six, to expand commercial use of single-crystal diamond, advancing material capability alongside the manufacturing volumes required to support most demanding applications,” says Orbray’s president & CEO Riyako Namiki.
