About SCIOCS

Message from the President

Thank you for visiting our website.

We started the research of Gallium Arsenide crystal growth at Hitachi, Ibaraki in 1971, and have more than 40 years history of the development and production of compound semiconductor materials.
Our business has newly transitioned to become one of the Sumitomo Chemical group companies as of April 1st, 2015.

The company name of "SCIOCS" is a combination of the words "SCIO" and "CS". "SCIO" means "I know" in the Latin language and "CS" is an abbreviation for "Compound Semiconductor". The name SCIOCS represents our company's philosophy that "SCIOCS has the deepest understanding of compound semiconductors, and provides the highest quality compound semiconductor materials."

Compound semiconductors are used for high-frequency, high power, and optical devices, and have a great potential for contributing to human society by saving energy and reducing environmental burdens. We will develop and produce the best materials to achieve this great potential.
By using the accumulated knowledge, we are also developing non-compound semiconductor materials. We greatly appreciate the opportunity to work with you.

Toshiya Saito
President
