Showa Denko to Establish New Base for High-Purity N2O in South Korea 
- Increasing Supply of Semiconductor-Processing Specialty Gas - 
Tokyo, Feb 26, 2014 - (JCN Newswire) -  Showa Denko (SDK) (TOKYO:4004) has
decided to increase its capacity for supplying high-purity nitrous oxide (N2O),
a specialty gas for semiconductor production, by cooperating with Dooam
Industrial (Dooam), of South Korea. Dooam is headquartered in Anseong, Gyeonggi
Province, and led by President Park Yup. 
SDK and Dooam have concluded a work commissioning agreement concerning the
production of high-purity N2O. The two companies have also agreed to jointly
construct a purification facility within the premises of Dooam's plant
near Seoul. The purification facility (with the capacity of 600t/y) is
scheduled for completion by the end of 2014, and commercial shipments will
start in 2015. As SDK is now operating a 1,200t/y plant at Kawasaki, Japan,
SDK's total high-purity N2O supply capacity, after the completion of the
new facility, will increase to 1,800t/y. 
High-purity N2O is used for deposition of an insulating oxide film in the
process of chemical vapor deposition (CVD) for producing semiconductors. For
this application, demand for high-purity N2O is growing at the rate of 10-15% a
year in Asia. In recent years, demand is also growing for use as a source of
oxygen for oxide film in the process of producing displays. SDK has therefore
decided to meet the growing demand for high-purity N2O in East Asia by creating
an additional production site in South Korea. 
Under its medium-term consolidated business plan "PEGASUS Phase II,"
SDK classifies its business in semiconductor-processing specialty gases,
including high-purity ammonia, in the category of "Growth" business.
SDK will aim to further expand the business on the world market, centering on
