Element Six and Orbray accelerate wafer-scale single-crystal diamond for volume production
Suppliers 16 June 2026 – Element Six (Oxford, UK), a synthetic diamond materials firm and part of the De Beers Group, and Tokyo-based Orbray Co Ltd have announced the next phase of their partnership to deliver wafer-scale single-crystal diamond (WSC). They have established a reproducible process for 3-inch WSC diamond, marking a significant improvement in size, uniformity, and manufacturability over conventional single-crystal diamond. Development of larger 4-inch substrates is underway. Meanwhile, 2-inch wafers optimized for epitaxial applications are nearing finalization, and 2-inch wafers for thermal bonding applications are being prepared for volume production at Element Six’s chemical vapour deposition facility in Gresham, Oregon. The collaboration focuses on advancing wafer size alongside manufacturing maturity to accelerate adoption of WSC diamond across 6G wireless components, power and RF electronics, sensing, thermal management, and quantum technologies. These developments represent a transition from R&D to scalable implementation, with the companies now refining production processes to support operational ramp-up for volume manufacturing at industrial scale. Element Six CEO Siobhán Duffy stated that the partnership builds on shared strengths in innovation and quality, translating into tangible progress towards wafer-scale single-crystal diamond at the quality and volumes needed by industrial customers. Orbray president & CEO Riyako Namiki noted that the milestones achieved so far are meaningful steps in expanding commercial use of single-crystal diamond, advancing material capability alongside the manufacturing volumes required for demanding applications.
