HexaTech Technology

Advanced semiconductor materials pave the way for novel applications in both new and existing market segments. Central North Carolina has a proven track record as a premier innovation center for advanced materials and information technology with a storied list of successful start-ups including RF Micro Devices and Cree. RFMD harnessed the performance of gallium arsenide (GaAs) to become a dominant supplier of RF integrated circuits for cellular handsets; while Cree perfected silicon carbide (SiC) technology to lead the explosive growth in LED lighting.

HexaTech is a recognized world leader in the development and commercialization of the next-generation semiconductor material, aluminum nitride (AlN). This wide bandgap semiconductor offers unique properties which enable the fabrication of first-in-kind devices, including long life UV-C light emitting diodes (LEDs) for disinfection applications, deep UV lasers for biological threat detection, high voltage switching devices for efficient power conversion, and RF (radio frequency) components for satellite communications.

High-performance AlGaN semiconductor devices currently face a crucial challenge in terms of achievable device quality. Fabricating these devices on lattice-matched, highly thermally conducting, single crystalline AlN wafers enables sophisticated, next-generation AlGaN-based devices with vastly superior performance and device lifetimes.

HexaTech has developed a proprietary crystal growth process that yields single crystalline AlN boules of exceptionally high quality, ideally suited for the fabrication of AlN substrates. By delivering substrates with 10,000 to 1,000,000 times fewer defects than competing technologies, HexaTech's AlN wafers enable breakthrough performance in the fabrication of high Al content AlGaN-based devices.
