Compound semiconductors (substrates)
GaAs and InP substrates
GaAs substrates (compound semiconductors) are used for smartphone power amplifiers and switches, LEDs (illumination, decoration, indicators), and solar cells. InP substrates are used for optical communication modules, etc.
GaN substrates
Gallium Nitride (GaN) substrates are widely used for optical devices in the blue-violate to green ranges due to their excellent material characteristics. In recent years, GaN substrates have been drawing attention for power devices. Many development projects are underway.
