HexaTech makes Defect-Free 2 inch AlN Substrate


Largest known single crystal AlN substrate that is completely free of macroscopic defects

HexaTech, a US supplier of single crystal AlN substrates, has announced the first known demonstration of a defect-free 2 inch diameter AlN substrate.

AlN substrates are used to make long life UV-C LEDs for disinfection applications, deep UV lasers for biological threat detection, and high voltage switching devices for efficient power conversion, and RF components for satellite communications.

HexaTech co-founder and CTO, Raoul Schlesser commented: “This is the largest known single crystal AlN substrate that is completely free of macroscopic defects, and accomplishes a long-standing goal as part of our 2 inch product development. Full-substrate reflection X-ray topography confirms this achievement, which will support and accelerate commercial production of high quality 2 inch material.”

“Less than a year from our first 2 inch demonstration, reaching this level of perfection is a testament to the efforts of the entire HexaTech team, and highlights our relentless drive to provide our customers the ultimate in AlN substrate performance”, stated HexaTech CEO, John Goehrke. “This capability establishes a new baseline for sustaining our vision of continued diameter expansion and greater market adoption”, he added.

HexaTech’s 2 inch diameter substrates, in addition to 35 mm and 25 mm substrates, are available now with standard lead times.
