Dusseldorf, Germany, August 10, 2023 – Crystal IS, an Asahi Kasei Group company, announced the successful fabrication of a 100 mm (4 inch) diameter aluminum nitride (AlN) single crystal substrate. This is the first aluminum nitride substrate of this size and demonstrates the scalability of the Crystal IS processes for AlN single crystal growth.
Aluminum nitride substrates have low defect density, high UV transparency, and low levels of impurities. AlN is attractive for a variety of applications such as UVC LEDs and power devices due to its extremely wide band gap and very high thermal conductivity. The 100mm substrate produced has a usable area of over 80% and thus meets the current requirements for UVC LEDs.
“We are very pleased to announce the fabrication of a 100mm aluminum nitride substrate,” said Dr Naohiro Kuze, Executive Fellow, Research Laboratory of Advanced Science and Technology at Asahi Kasei. “This success demonstrates that aluminum nitride has commercial viability not only for UVC LEDs, but also for other industries.” Founded in 1997, Crystal IS provides UVC with its commercial process for 50mm (2 inch) diameter native aluminum nitride substrates -LEDs here. These LEDs enable the highest reliability and performance at germicidal wavelengths of 260nm – 270nm.
“This demonstrates the scalability of our processes to produce quality aluminum nitride parts,” said Eoin Connolly, President and CEO of Crystal IS. “We are proud of the team’s achievement and its impact on the entire semiconductor industry.” Crystal IS currently produces thousands of 50mm substrates annually to support the production of its Klaran and Optan product lines. The commercialization of 100mm AlN substrates will quadruple device output from the existing Green Island facility footprint. It will also enable the development of new applications on aluminum nitride substrates, as it can be integrated into existing manufacturing lines for power and high-frequency devices with alternative materials.
Crystal IS will present advances in 100mm substrates at the 23rd American Conference on Crystal Growth and Epitaxy August 13-18 in Tucson, Arizona. For more information on aluminum nitride and Crystal IS products, please visit cisuvc.com or [email protected].
