Evonik starts up new monosilane plant in Japan

Investment in the future-oriented solar energy and electronics markets

07-Jun-2011 - Japan

Evonik Industries and its partner Taiyo Nippon Sanso Corporation (TNSC) officially started up the new integrated production facility for monosilane and AEROSIL® in Yokkaichi, 400 kilometers south of Tokyo (Japan). Evonik has thus realized a future-oriented project to serve the growing photovoltaic and electronic markets. The project volume was around €150 million and the facility was the company’s largest single project in 2010. Evonik has a long-term agreement to supply monosilane to TNSC. Monosilane is used in the production of thin film solar cells, flat-screen displays and semiconductors for the electronics industry. Applications for AEROSIL® include processing into plastics, colorants and coatings.

At the opening ceremony in Yokkaichi, Klaus Engel, Chairman of Evonik's Executive Board, commented: “This substantial investment in Japan expands our significant market and technology position in the future-oriented solar energy market. It also makes a further important contribution to the global resource efficiency megatrend.”

The process used to produce monosilane at this new plant was developed by Evonik, which already operates a facility using this technology in Rheinfelden (Germany). The new plant in Yokkaichi will serve the Asian market with electronic-grade monosilane.
