TSMC says no to Renesas buy

Contrary to news reports in Japan, Taiwan Semiconductor Manufacturing Co. Ltd, has no intention of purchasing a wafer fab from Renesas Electronics Corp., a report in Focus Taiwan said, attributing the statement to Morris Chang, chairman, TSMC.

It was reported in Japan that Renesas was negotiating with TSMC to take over a wafer fab in Yamagata, including about 1,400 employees there, as part of TSMC's role as a foundry supplier of MCUs to Renesas.

The move would have been part of a massive re-organization that could see Renesas close or sell more than half its domestic factories and trim its workforce by about 12,000 people or 30 percent.

Renesas has been making losses since its formation in 2010 as a joint venture that brought together the chip making interests of Hitachi, Mitsubishi Electric and NEC. On July 3 the company announced some details of its restructuring including offers to workers to take early retirement or to leave the company for about 5,000 workers. However, plans to trim the company's market engagement and to increase the outsourcing of manufacturing were vague.

Chang said he expects TSMC to provide more advanced chip production to TSMC but that the acquisition of the wafer fab was not on TSMC's agenda, the report said.

In May the two companies announced that they had agreed to extend MCU technology collaboration to include 40nm embedded flash process technology and that in addition TSMC will be able to make the Metal-Oxide-Nitride-Oxide-Silicon (MONOS) embedded flash platform available to other customers.
