Silicon monoxide

In 1961, we became the first in Japan to successfully manufacture silicon monoxide (SiO). Since then, in close link with SiO users, we have been keeping efforts to improve quality and to reduce prices. Through these effrots, we have gained a high reputation among electrical and electronic component manufacturers, optics manufacturers and manufacturers of protective coatings for plastic lenses. Most recently, the successful development of silicon monoxide appropriate for the packaging films for its gas barrier properties has contributed to lessening the load on the environment.

Silicon monoxide properties

The most outstanding feature of our silicon monoxide is its high purity. Semiconductor silicon grade high purity silicon is used as the raw material, and the vacuum technology from titanium sponge manufacture is leveraged to ensure a reliable supply of high quality products that other manufacturers cannot come close to matching.

Applications

1. Optical applications, antireflective coatings, absorptive coatings, protective coatings
2. Protective insulation coatings for liquid crystal conductive films
3. Protective coatings for semiconductor elements
4. Dielectrics for thin film capacitors
5. Antireflective coatings for solar cells, etc.
6. Deposition material for gas barrier films
7. Others
