SDK to Strengthen High-Purity Ammonia Business for Electronics
--Increasing Capacity to 5,000 t/y via Expansions in Japan, Taiwan and China--

 June 29, 2011

Showa Denko K.K. (SDK) will increase its production capacity for high-purity ammonia to meet growing demand from the electronics industry.  Specifically, production capacities at three sites—Japan, Taiwan, and China—will be increased from the current levels of 1,000 t/y, 1,500 t/y and 500 t/y; to 1,500 t/y, 2,500 t/y and 1,000 t/y, respectively, by the end of 2011.

The capacity increase will be carried out through expansions of filling/storage facilities and improvement in production efficiency.  As a result, the Showa Denko Group’s total high-purity ammonia production capacity will increase from 3,000 t/y at present, to 5,000 t/y.  

High-purity ammonia is used as a material gas in the production of liquid crystal display (LCD) panels, gallium-nitride LEDs, solar cells based on polycrystalline silicon, and semiconductors.  Anticipating further growth in the electronics market in East Asian countries and to ensure stable supply of high-purity ammonia, SDK has decided to increase production capacities at its sites in Japan, Taiwan and China.  

Under its medium-term consolidated business plan PEGASUS, SDK classifies its business in high-purity ammonia and other high-purity gases (for semiconductor/display production) under the category of “growth” business.  SDK will continue to encourage the growth of this business by increasing competitiveness of existing products and developing new products.
