SDK Ups High-Purity Ammonia Production Capacity in Taiwan

Showa Denko K.K.
December 6, 2007

Showa Denko K.K. (SDK) has expanded the high-purity ammonia production capacity at its subsidiary Taiwan Showa Chemicals Manufacturing Co., Ltd., from 1,000 tons a year to 1,200 tons a year, to meet growing demand from the electronics industry of East Asian countries.

Reflecting sharp rises in the production of semiconductors and liquid crystal displays (LCDs) in the region, demand for high-purity ammonia is also increasing for use as a nitride-film-forming gas in the production process. Furthermore, high-purity ammonia is increasingly used in the production of gallium-nitride LEDs and solar cells.

Taiwan Showa Chemicals Manufacturing began producing high-purity ammonia in November 2005. As a result of the capacity expansion, SDK has further strengthened its position as a stable supplier of high-purity ammonia to its customers in Taiwan.

Under the current medium-term consolidated business plan, the “Passion Project,” SDK is expanding the semiconductor-processing materials operation as one of the “growth driver” businesses. As part of the operation, SDK is supplying high-purity ammonia from its production sites in Japan and Taiwan to the growing East Asian market. SDK expects that its annual sales of semiconductor-processing materials, including specialty gases, will increase to around ¥30 billion next year.
