Electronic Materials We support cutting-edge IT and electronics technologies through the provision of our high-purity and high-quality key materials.

We manufacture and distribute electronics materials indispensable for the development of information society, such as high-purity metals and compounds, optical components and others. Particularly, when it comes to high-purity metallic arsenic for gallium arsenide semiconductors, we supply most of the domestic demand as well as exporting them in high volume, and have established a solid position as one of the world’s leading manufacturers.

High-Purity Metals and High-Purity Compounds

High-Purity Metals and High-Purity Compounds

High-purity metallic arsenic of which we have a large share in the global market is used to make gallium arsenide semiconductors, and is also used as dopants of n-type Si. In addition, compounds of high-purity metallic arsenic and Calcogen (S, Se etc) are used as trans-IR devices and glassy semiconductors.

Optical Components

Optical Components

We offer products that connect light technology with modern demands including optical components for laser cutters, infrared thermometers and night vision cameras, as well as polishing and coating.

Aluminum Nitride Ceramics

Aluminum Nitride Ceramics

Aluminum nitride ceramics are highly thermal conductive, thermal radiative and have a good electrical insulation property. They are used in components for semiconductor manufacturing equipment, substrate materials and fillers, and more as their applications are expanding.

Cores and Coils

Cores and Coils

As we have the technology to enable us to manufacture cores, we can make proposals and prototypes to satisfy any of our clients’ needs including materials and shapes.
Our high-quality cores are highly recognized due to our experience in delivering in-car components over the years.

Gallium Nitride Substrates

Gallium Nitride Substrates

Our high-quality gallium nitride substrates are made by the HVPE method. As they have low dislocation density, they are the best materials for blue-violet laser diodes or wafers for highly-bright white LEDs.
