Shin-Etsu halts LCD material output over chemical leak

Post Time:Aug 18,2009Classify:Industry NewsView:323

Japan's Shin-Etsu Chemical Co Ltd (4063.T) said on Friday a chemical leak forced it to halt production of synthetic quartz, used to make large LCDs, and it did not know when it would resume.

Shin-Etsu Chemical, the world's biggest maker of silicon wafers used to make chips, stopped some lines at its Naoetsu plant in western Japan after it discovered toxic tetrachlorosilane gas leaking from production equipment.

No injuries or illness were reported. The local fire department stopped synthetic quartz production at the plant and is investigating the cause of the leak.

Synthetic quartz, which is uniform in shape and heat resistant, is used to etch ultra-fine circuit patterns on display panels for large-size TV screens, and is also used in fibre optic cables.

Production of other products, such as methylcellulose used to coat pills and make paint, is proceeding as usual at the factory, and it has a stockpile of synthetic quartz, a Shin-Etsu spokesman said. It is the only plant at which it makes the material.

Shin-Etsu competes with Asahi Glass Co Ltd (5201.T) in synthetic quartz. The material made up 2 percent of Shin-Etsu's sales in the year ended in March. (Reporting by Mayumi Negishi; Editing by Michael Watson)
