What HexaTech does
HexaTech, Inc. is a privately held specialty semiconductor materials company founded in 2001 and headquartered in Morrisville, North Carolina. It develops and manufactures single crystalline aluminum nitride (AlN) substrates using a proprietary Physical Vapor Transport (PVT) crystal growth process operating at temperatures exceeding 2000°C, producing what the company describes as the world's highest quality AlN boules with average dislocation densities of 10^2-10^4 cm-2 — up to six orders of magnitude lower than competing technologies. Its product portfolio includes AlN-10, AlN-20, and AlN-30 substrate product lines (c-plane and m-plane orientations, 2-inch and 3-inch diameters), an N-polar terminated variant for HEMT structures, and the UVSure™ UV-C LED device line demonstrating 6 mW output at 263 nm. These substrates enable UV-C LEDs for disinfection, deep-UV lasers for biological threat detection, high-voltage AlN-based power conversion devices, and RF components for satellite communications.
The company operates a B2B enterprise model, selling substrates via direct sales from its U.S. headquarters and through exclusive sales representatives in China (Beijing Jiaxing Chengxin), Japan (MO Sangyo, Okaya & Co.), and South Korea (K1 Solution). Pricing is quote-based and not publicly disclosed. HexaTech has secured cumulative U.S. government funding of approximately $18 million-plus across DARPA LUSTER ($4M), ARPA-E (~$4M), and DARPA UWBGS (potential $10.2M over 3 years) programs. Since March 2020, HexaTech has operated as a wholly-owned subsidiary of Stanley Electric Co., Ltd., a Tokyo-listed automotive lighting manufacturer, with the parent serving as both customer and capital backer. The company maintains a headcount in the 11-50 range and serves enterprise customers including OSRAM Opto Semiconductors and Tokuyama Corporation.

- Coherent (formerly II-VI): Coherent produces SiC and other compound semiconductor substrates serving power electronics, RF, and optoelectronic applications. It competes with HexaTech indirectly as customers evaluate AlN versus SiC substrate technologies.
- ROHM Semiconductor: ROHM manufactures SiC power devices and is investing in next-generation wide bandgap semiconductors. As a downstream device maker, it represents both a potential customer for HexaTech's AlN substrates and a competitor via SiC technology.
- Qorvo: Qorvo is a leading RF semiconductor company using GaN-on-SiC technology for high-frequency, high-power applications. It serves as both a potential customer for HexaTech's AlN substrates in next-gen RF devices and a benchmark for substrate technology choices.
Emerging players
- Soitec: Soitec specializes in engineered substrates including SmartSiC and other advanced wafer technologies. It represents an adjacent player in specialty semiconductor substrates targeting power and RF applications where HexaTech's AlN competes.
Others
- Nichia: Nichia is a global leader in LED manufacturing, including UV-C LEDs. While primarily a downstream customer for HexaTech's substrates rather than a competitor, Nichia is a critical reference customer whose substrate choices influence the broader UV LED market.
