II-VI Licenses Element Six Diamond tech


Single-crystal diamond technology will complement II-VI’s polycrystalline diamond platform

II‐VI and Element Six have announced a strategic collaboration that will expand II-VI’s diamond platform, accelerating the development of new applications by licensing Element Six’s single-crystal diamond technology. II-VI is licensing IP and equipment from Element Six.

Applications of advanced power and RF electronics, including for 6G wireless components and quantum computing, are expected to drive the adoption of single-crystal diamond, a difficult material to manufacture but well known for its optical, mechanical, thermal, and electrical properties.

“Element Six has invested hundreds of millions of dollars for over 70 years to become a world leader in single-crystal diamond engineering and growth. Its unique capabilities complement II‑VI’s proprietary polycrystalline diamond, a material we already manufacture at scale,” said Steve Rummel, SVP, Engineered Materials and Laser Optics Business Unit, II‑VI.

“This exciting collaboration is consistent with II-VI’s innovation strategy of making early investments in technology platforms that are process- and capital-intensive, and that require time to evolve, mature, and scale, so we can enable our customers’ technology roadmaps.”

“With its diverse global manufacturing footprint, growth markets expertise, and a successful vertically integrated structure, II-VI is one of the largest listed photonics and compound semiconductor companies. These elements make it an ideal partner to accelerate the market adoption of this remarkable material,” said Daniel Twitchen, chief technologist, Element Six.

“Besides future opportunities for electronics, there is also a wide range of near-term applications driving the demand for accessible high-quality single-crystal diamond, including high-power optics, high-durability parts, and high-performance thermal-management systems. We look forward to enabling these and many new markets through this strategic collaboration with II-VI.”
