Semiconductor Materials
High-purity Gallium is used as a raw material for compound semiconductors such as substrates for LEDs and Laser Diodes. Nichia’s infrared LED epitaxial wafers are widely used for high power and fast response infrared LEDs for various fields, such as surveillance cameras and sensors for security systems, and as high-speed photocouplers for many different applications.
High-purity Gallium
Gallium is an essential metal in the manufacture of semiconductors. It is widely used in LEDs, LDs, GaAs and GaN substrates, dopants, etc. Gallium is also expected to be used as a next-generation material for power semiconductor devices and is attracting attention as an important rare metal that supports advanced technologies.
