(Yicai Global) May 19 -- Shares in Do-Fluoride New Materials surged by the exchange-imposed trading limit today after the Chinese manufacturer of inorganic fluoride products said it has been appointed an official supplier of high-purity electronic chemical materials to the world’s biggest chip foundry Taiwan Semiconductor Manufacturing Company.

Do-Fluoride’s share price [SHE:002407] soared by 10 percent to CNY37.63 (USD5.57).

Do-Fluoride started bulk deliveries to TSMC’s factory in Nanjing, eastern Jiangsu province after the client conducted on-site inspections and product tests, the Jiaozuo, central Henan province-based company said yesterday.

The name of the product was not revealed, but Do-Fluoride supplies high-purity electronic chemicals, such as electronic-grade hydrofluoric acid, to a growing number of clients in China, the US, South Korea and other countries.

The partnership with Hsinchu-based TSMC will have a positive effect on the growth of the company’s electronic chemicals business, Do-Fluoride added.
