Business field

SCIOCS is a leading company in compound semiconductor crystal and epitaxial growth field.

We specialize in providing the highest quality GaN and GaAs compound semiconductor substrates and epitaxial*1 wafers for various applications including microwave and optical devices.

For microwave devices, our GaAs and GaN epitaxial wafers enable the most advanced RF (radio-frequency) power amplifiers and switches, used in cell phones, base stations, radars, and wireless LANs. We also have rolled out GaN substrates for next generation high power devices, and currently are working on both diameter upsizing and quality improvement.

For optical devices, our GaN substrates and GaAs epitaxial wafers are used in Laser Diodes (LD) for Blu-ray*2/DVD/CD drives and high-end projectors. Our materials are also used to make LEDs for general lighting and LCD backlight applications.

To realize a society using materials of low enviroment load, we are also developing lead-free piezoelectric thin films and boron-doped diamond (BDD) electrodes.
