Semiconductor Business

Our semiconductor products include high-purity gallium, gallium arsenide wafers, and LED.

The LED, which holds a substantial share in the proximity sensor and medical equipment fields, is utilized in our daily life and its substantial future growth is expected. The high-purity gallium, for which we hold the top share in the world market, is used as a raw material for the wafers and LEDs that are manufactured in-house and are also supplied to other manufacturers.

We are also promoting commercialization of gallium nitride HEMT Epiwafers that are expected to be used for next generation mobile phones, millimetre wave communications, and hybrid cars. We are also developing the ultraviolet LED, which is expected to be used in a wide range of applications including medical treatments and disinfection.
