Epistar and UMC plan LED joint venture in China

Taiwan-based LED supplier Epistar Corp. and United Microelectronics Corp. (UMC) have formed an LED chip joint venture based in Mainland China.

Recently, Epistar has revealed that it plans to invest $128 million in two China-based ventures, including $120 million in an LED epiwafer and chip manufacturing venture tentatively called Changzhou Co. In the second filing, Epistar said it would invest $8 million in another LED epiwafer and chip venture in China, United LED Corp. UMC said in a filing dated Dec. 15 that it would also invest $8 million in a Mainland China venture called United LED Corp. A spokesperson for UMC Wednesday confirmed that the firm is joint venture between UMC and Epistar. United LED is based in the province of Shandong, in the eastern coastal area of China, according to the filings. Taiwan-based IT news reported that Epistar and UMC will each have a 50 percent stake in United LED.

UMC said in a regulatory filing of its own that it would invest $1 million in a company called U-Lighting Opto Electronic Inc. —also based in Shandong— through a firm called United Lighting Opto-Electronics Investment Ltd. It was not immediately clear whether this investment is related to United LED. UMC described the main business of United LED as LED chip design, manufacture and sales.
