Showa Denko (SDK) (TOKYO:4004) has increased the production capacity for high-purity ammonia (a specialty gas for semiconductor production) at its manufacturing subsidiary in Zhejiang Province, China, from 1,000 t/y to 2,000 t/y. The expanded facility started operation this month.

High-purity ammonia is used for nitride film deposition in the manufacturing processes of liquid crystal display (LCD) panels and light-emitting diodes (LEDs). While LEDs are used for general lighting and backlight for LCDs, the LED market in China is growing for such new applications as landscape lighting and large screens, in addition to general lighting. Thus, SDK has strengthened its supply system to meet the growing demand for high-purity ammonia in East Asia, where electronics production sites are integrated.

SDK is operating three high-purity ammonia plants, one each in Japan, Taiwan, and China. Following the capacity expansion in China, SDK now has a total high-purity ammonia production capacity of 6,000 tons a year*. Under its consolidated business plan PEGASUS Phase II, SDK classifies the semiconductor-processing high-purity gas business as a “Growth” business. SDK will aim to further globalize the business this year, strengthening the production/distribution system in Asia and expanding sales.

*SDK’s high-purity ammonia production sites and their capacities, as of January 31, 2014:
1. Japan: SDK’s Kawasaki Plant (Kawasaki City) 1,500 t/y
2. Taiwan: Taiwan Showa Chemicals Manufacturing Co., Ltd. (Tainan City) 2,500 t/y
3. China: Zhejiang Quzhou Juhua Showa Electronic Chemical Materials Co., Ltd. (Quzhou City, Zhejiang Province) 2,000 t/y
