Crystal IS and Asahi Kasei have achieved 99% usable area on 100 mm bulk aluminum nitride substrate

Rhea-AI Summary

Crystal IS, a subsidiary of Asahi Kasei, has announced the successful serial production of 100 mm diameter single-crystal aluminum nitride (AlN) substrates with a 99% usable area. This marks a significant improvement from the previous 90% in Q1 CY24. The substrates are to be manufactured in the United States and will enhance the performance and reliability of UVC LEDs, RF, and power devices. The announcement follows the first-ever 100 mm diameter AlN launch in August 2023, which won the Grand Prize in the Semiconductor of the Year Awards. These substrates are set to accelerate the development of new applications and integrate seamlessly into existing fabrication lines.

Positive

• 99% usable area achieved on 100 mm diameter AlN substrates.
• Substrates to be manufactured in the US, potentially boosting local manufacturing.
• Improved wafer quality from 90% in Q1 CY24 to 99% in Q2 CY24.
• AlN substrates to enhance performance and reliability of UVC LEDs, RF, and power devices.
• Winning the Grand Prize in the Semiconductor of the Year Awards.
• Expansion beyond UVC LEDs to new applications in RF and power devices.

Negative

• No immediate revenue figures provided.
• Potential risks of manufacturing exclusively in the US, such as higher costs.
• Dependency on successful integration into existing fabrication lines.

Following the first reported 100 mm diameter AlN in 2023, the company now announces improved wafer quality based on specification for UVC LEDs

NEW YORK & TOKYO & DÜSSELDORF--(BUSINESS WIRE)-- Crystal IS, an Asahi Kasei company, today announced the successful serial production of 100 mm diameter single-crystal aluminum nitride (AlN) substrates with 99% usable area, based on current requirements for UVC LEDs, with manufacturing to take place in the United States. The ultra-wide bandgap and high thermal conductivity of AlN help to improve device reliability and performance not only in UVC LEDs but also in next-generation RF and power devices.

“The improvement of our large diameter substrate quality over the last nine months showcases the expertise of our team in Crystal Growth,” said Eoin Connolly, President and CEO of Crystal IS. “The inherent thermal benefits of aluminum nitride can enable higher performing RF and power devices in mission critical and telecom applications—we are excited to work with our partners to further develop this material to meet their needs.”

This achievement follows the company’s announcement of the first-ever recorded 100 mm diameter in August 2023, which won the Grand Prize in the category of Electronic Materials for Semiconductors in the 2024 Semiconductor of the Year Awards. The Semiconductor of the Year Awards are organized by Electronic Device Industry News, an industry journal published in Tokyo by Sangyo Times, Inc.

Crystal IS manufactures bulk single crystal AlN substrates at its headquarters in Green Island, New York, and began selling 2-inch diameter substrates for research and development in RF and power devices in late 2023. This 100 mm diameter milestone accelerates the development of new applications on AlN substrates as it integrates into existing fabrication lines for RF and power devices using alternative materials. The company plans to offer 100 mm diameter substrates, which will be exclusively manufactured in its US facility, to key partners this year as they continue to expand beyond UVC LEDs.
