Element Six and Orbray establish 3-inch diamond process
Element Six (E6) and Orbray have successfully established a reproducible process for 3-inch wafer-scale single crystal (WSC) diamond.
The materials companies say this latest stage in their partnership represents 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 optimised for epitaxial applications are nearing finalisation, while 2-inch wafer diamonds for thermal bonding applications are being prepared for volume production at E6’s 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.
“Our partnership with Orbray was built on shared strengths in innovation, quality and technical expertise,” said Siobhán Duffy, CEO of Element Six. “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.”
Riyako Namiki, president and CEO at Orbray, added: “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.”
