SDK to strengthen capacity in East Asia for high purity ammonia
The company is expanding total capacity by 5,000 tonnes per year in Japan, Taiwan and China to cope with demand for ammonia gas, which is used in many electronic applications including gallium nitride LEDs.
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 GaN LEDs and other compound 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.
Showa Denko Group’s high-purity ammonia production sites: are in
1. Japan: Kawasaki Plant, SDK (Kawasaki City)
2. Taiwan: Taiwan Showa Chemicals Manufacturing Co., Ltd. (Tainan City; owned 90% jointly by SDK
and its subsidiary)
3. China: Zhejiang Quzhou Juhua Showa Electronic Chemical Materials Co., Ltd. (Quzhou, Zhejiang Province; owned 51% by SDK)
AkzoNobel to expand in Texas with two plants for LED precursors
The new TMGa production plant, to be completed in 2012, will be three times the size of the existing unit. The second facility for TMIn manufacture will increase capacity by 400 % and should be completed by Dec 2011.
Responding to continued strong global demand for its High Purity MetalOrganics (HPMO) product range, AkzoNobel will significantly expand its production capacity for two of its key products; Trimethyl Gallium (TMGa) and Trimethyl Indium (TMIn).
The HPMO business, part of Business Unit Functional Chemicals, is a leading producer of semiconductor grade indium-, gallium-, aluminum and zinc- and magnesium-based metalorganics which are used as precursor materials in the production of LEDs, solar cells and other semiconductor devices.
In June 2010 AkzoNobel doubled its production capacity for TMGa. The capacity of this unit has been quickly doubled again in January 2011, and the new capacity has been successfully ramped up during the past four months, making AkzoNobel the largest global producer of this specialty chemical.
“Our customers’ response to these expansions has been very positive, and their continued strong demand keeps absorbing our recently enlarged capacities” says Michiel Floor, Global Business Manager of the HPMO product group. He adds: “We firmly believe in significant long term growth of the LED and III/V solar cell industries, so we have decided to advance our plans for further major capacity additions with two new world-scale production units.”
The company plans to build a large new production July 2011
