HexaTech achieves defect-free 2”-diameter aluminium nitride substrate

As part of its R&D program (combined with the direct support of its strategic business partners), HexaTech of Morrisville, NC, USA – which manufactures single-crystal aluminium nitride (AlN) substrates for long-life UV-C LEDs in disinfection applications, deep UV lasers in biological threat detection, and high-voltage power switching devices in efficient power conversion as well as RF components in satellite communications – has announced what it reckons is the first demonstration of a defect-free 2”-diameter AlN substrate.

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” product development,” says co-founder & chief technology officer Dr Raoul Schlesser. “Full-substrate reflection x-ray topography confirms this achievement, which will support and accelerate commercial production of high-quality 2” material,” he adds.

Less than a year from our first 2” demonstration, reaching this level of perfection is a testament to the efforts of the entire HexaTech team,” says CEO John Goehrke. “This capability establishes a new baseline for sustaining our vision of continued diameter expansion and greater market adoption.”

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