U.S. Subsidiary HexaTech Announces 100 mm Diameter Single-Crystal Aluminum Nitride Substrate Product
Corporate
HexaTech, Inc. (“HexaTech”), a U.S. subsidiary of Stanley Electric Co., Ltd. (“Stanley Electric”) engaged in the development and manufacturing of semiconductor substrates, has commercialized a 100 mm diameter single-crystal aluminum nitride (AlN) substrate.
For more than 20 years, HexaTech has been engaged in the research and development of single-crystal AlN substrates and the advancement of mass-production technologies. Following the commercialization of its 3-inch (76.2 mm) diameter substrate in February 2026, HexaTech has now achieved a further increase in substrate size with the commercialization of its 100 mm diameter substrate. Going forward, HexaTech aims to develop substrates with diameters of 150 mm and beyond.
Benefits of Larger-Diameter Substrates
Larger-diameter substrates enable lower device costs and increased production volumes. These benefits are expected to contribute to improved productivity in the manufacturing of optoelectronic and high-power radio frequency (RF) devices.About Aluminum Nitride (AlN) Substrates
Single-crystal AlN is a type of wide-bandgap semiconductor material*1 and is expected to be used primarily in the following applications:- UV-C light emitting diodes (LEDs) for disinfection applications
- Deep UV lasers for biological threat detection
- High voltage switching devices for efficient power conversion
- RF components for satellite communications
*1: Semiconductor materials with properties that enable them to perform effectively under high-voltage and high-temperature conditions compared with silicon (Si). They are expected to be increasingly used in next-generation power semiconductors, RF devices, light-emitting devices, and other applications.
Exhibition at IWN 2026
The newly commercialized 100 mm diameter AlN substrate will be exhibited at the 13th International Workshop on Nitride Semiconductors 2026( IWN 2026), to be held in Kumamoto Prefecture from November 8 to 13, 2026.Stanley Electric will continue to leverage the technologies of its group companies to explore the possibilities of light and contribute to the advancement of next-generation optoelectronics and semiconductor devices.
