(Yicai Global) July 1 -- Shares of China's Sinyang Semiconductor Materials jumped to a more than six-month high after the chip chemicals maker said it has received the first order for its newly certified raw material for integrated circuit manufacturing.

Sinyang's stock price [SHE:300236] rose as much as 14.4 percent to CNY55.55 (USD8.60) intraday, the highest since last December.

Reaching the milestone lays a foundation to explore the market for the new 248-nanometer KrF photoresist, the Shanghai-based company said in a statement yesterday, without disclosing more details about the order nor the name of the certifying authority.

China produces less than 5 percent of the KrF photoresist needed in making eight-inch silicon wafers, according to public data. Suzhou-based Crystal Clear Chemical is far along in developing a related product to enter the slim sector which is mainly occupied by a unit of Red Avenue New Materials Group which mass-produces about 10 tons of the material a year.

As China builds more wafer factories, the country's successful development of photoresist products is important amid the export restrictions abroad, Sinyang added. The latest KrF photoresist is mainly used for chips with processes from 350 nanometers to 14 nanometers.
