Showa Denko K.K. (SDK; Tokyo, Japan; www.sdk.co.jp) has expanded its capacity to supply high-purity ammonia, which is widely used in production processes for electronic materials, by stepping up the production capacity of a plant owned by its manufacturing subsidiary in Taiwan from 2,500 to 3,500 metric tons per year (m.t./yr). The Showa Denko Group has three bases to produce high-purity ammonia, which are located in Japan, Taiwan and China. As a result of this step-up, the total production capacity of these three bases has been increased to 7,000 m.t./yr.
High-purity ammonia is a specialty gas used for forming nitride film in processes that produce electronic parts, such as compound semiconductors, including LEDs and LCD panels. SDK has been producing and selling high-purity ammonia in Taiwan since 2005. Furthermore, the demand for high-purity ammonia is expected to increase in the region in the future.
