HexaTech Inc. has developed a proprietary growth process for the fabrication of single crystalline aluminum nitride (AlN) boules ideally suited for the fabrication of high-quality AlN substrates. The III-nitride industry currently faces a crucial challenge in terms of device quality. The use of lattice-matched, highly thermally conducting, single crystalline AlN substrates will enable the fabrication of sophisticated, next-generation III-nitride devices with superior performance and device lifetimes. Application for AlN include high-power, high-frequency electronic devices and deep-UV LEDs, lasers and detectors.
