Semiconductor material supplier HexaTech announced the launch of its deep-UV transparent 2-inch diameter, single crystal aluminum nitride (AlN) substrate product line. This capability is targeted to directly support commercial production of UVC LED. The company will also reveal its detect-free AlN substrate capability in May of last year. "This deep-UV transparency capability, especially when coupled with HexaTech's market-leading crystal quality, continues to demonstrate both the wide-ranging potential of the AlN platform, and the outstanding technical...

HexaTech Inc. announced today the signing of two strategic agreements with OSRAM Opto Semiconductors GmbH, of Regensburg, Germany. 

HexaTech announced the demonstration of its first generation UVSure™ UV‐C LED, based on HexaTech’s proprietary and world-leading aluminum nitride (AlN) substrate material. The 263 nm wavelength device achieves 6 mW in a 0.15 mm2 active area die. When scaled to our second generation larger footprint, the die is expected to produce approximately 24 mW, which is twice the radiant flux of competitive products.

HexaTech demonstrated optically pumped, AlGaN-based lasers grown on single crystalline AlN substrates , to develop its UV-C LEDs. Hexatech AlN wafer production process Laser structures fabricated at HexaTech and tested in collaboration with North Carolina State University (NCSU) featured lasing thresholds as low as 85 kW/cm2 at wavelengths of 264 and 280 nm. HexaTech says this AlN substrate platform is suited for UV-C opto-electronic applications. “Our recent results show convincing evidence of the feasibility of a solid-state UV-C ...

HexaTech, Inc. has developed a new class of high transparency single crystal Aluminum Nitride (AlN) material. This new material provides a significant reduction in optical absorption in the UV-¬C wavelengths, resulting in dramatic improvements in the processing and performance of UV-¬C optoelectronic components. according to the company,this enhanced material will offer an improvement of lifetime and power output for UV-¬‐C LEDs. For the rapidly growing water purification market, the requirement for extended lifetime and improved efficiency are critica...
