Aluminum nitride substrates have low defect densities, high UV transparency, and low concentrations of impurities. AlN is attractive for a variety of industries, such as UVC LEDs and power devices, due to its ultra-wide bandgap and very high thermal conductivity. The 4-inch substrate produced shows a usable area of over
“We are extremely excited to announce the achievement of a 4-inch bulk aluminum nitride substrate,” said Dr. Naohiro Kuze, Executive Fellow at the Research Laboratory of Advanced Science and Technology, Asahi Kasei. “This accomplishment signifies that aluminum nitride is commercially viable for new industries beyond just UVC LEDs.”
Founded in 1997 to develop native aluminum nitride substrates, Crystal IS manufactures UVC LEDs on its commercial process for 2-inch diameter substrates. These LEDs enable industry-leading reliability and performance at the ideal germicidal wavelengths from 260 nm – 270 nm. The current capacity of the facility can meet the volume requirements for consumer devices using UVC LEDs based on the existing 2-inch production line.
“This indicates the scalability of our processes to deliver quality devices on Aluminum Nitride,” said Eoin Connolly, President and CEO of Crystal IS. “We are proud of the team’s accomplishment and its impact on the semiconductor industry as a whole.”
Crystal IS currently produces thousands of 2-inch substrates annually to support the production of its Klaran and Optan product lines. The commercialization of 4-inch AlN substrates will quadruple the device output of the existing footprint of the
Crystal IS will present the progress on 4-inch substrates at this month’s 23rd American Conference on Crystal Growth and Epitaxy in
