China's TSMC Sold Tens of Thousands of Faulty Chip Materials to Global Clients
(Yicai Global) Jan. 30 -- Taiwan Semiconductor Manufacturing, the primary chipmaker for iPhones, has delivered tens of thousands of substandard wafers to major domestic and international firms due to unqualified raw materials. The incident may only intensify TSMC's pinch involving expectations of narrowing revenues./n/n/n/n/nAn unspecified source supplied TSMC with unauthorized photorest chemicals, which may cause the buyer to lose millions of US dollars, online news outlet Jiemian reported yesterday. 

The price of TSMC's silicon wafers averaged USD1,382 each last year, market research firm IC Insights told Jiemian, adding that losses of defective chips may expand because the products involved included advanced 16 and 12-nanometer technologies.

For the Hsinchu-based buyer, th a bad time for mtakes. TSMC inquired if chip parts firms could give up to 10 percent dcounts while anticipating th year's annual revenue to grow 3 percent or less from last year, Yicai Global reported yesterday, citing Taiwan-based daily newspaper Digitimes. One of the reasons slowing sales of Cupertino-based Apple's handsets in China. 

The affected wafers are mainly supplied to California's graphics processing units maker Nvidia, Hsinchu-based chip company MediaTek, Shenzhen's telecoms giant Huawei Technologies, semiconductor firm HiSilicon Technologies and others, the report added.

TSMC expects to restore its capacity in the first quarter and will try its best to deliver the wafers to customers on time while requesting compensation from the raw material supplier, the report said, citing TSMC spokesperson Sun Youwen. The incident will not affect the firm's financial performance during th quarter, Sun added.

Japan's Shin-Etsu Chemical, Tokyo-based JSR and Michigan-headquartered Dow Chemical are the three companies that provide TSMC with photorest chemicals. The buyer and suppliers are still investigating the cause for the incident.
