TOKYO, Japan and Heilbronn, Germany, March 31, 2011 – Renesas Electronics Corporation (TSE: 6723), a premier supplier of advanced semiconductor solutions, and TELEFUNKEN Semiconductors GmbH & Co. KG, an automotive-qualified, mixed-signal, high-voltage (HV) power management and SOI-based manufacturer, today announced that they have signed an agreement under which Renesas Electronics America Inc. will sell its semiconductor wafer fabrication facility in Roseville, California, to TELEFUNKEN Semiconductors International LLC, a company that includes TELEFUNKEN Semiconductors GmbH. The sale price is approximately 53 million U.S. dollars, and the closing for the sale is planned for May 2, 2011.

As part of the strategies decided through its 100-Day Project announced on July 29, 2010, Renesas Electronics has been considering and implementing various measures to improve manufacturing efficiency by promoting larger wafers, finer process node, and production concentration. In line with these measures, the company decided to sell Renesas Electronics America’s facility in Roseville, California, to TELEFUNKEN Semiconductors International, which has been searching for a new manufacturing facility to expand its semiconductor business.

TELEFUNKEN Semiconductors International intends to utilize the 200-millimeter (mm), eight-inch line at the Roseville factory to manufacture its own analog/mixed-signal, HV products and the products for its strategic foundry partners. TELEFUNKEN Semiconductors International also will enter into a supply agreement with Renesas Electronics for manufacturing services at the Roseville factory. Under this agreement, TELEFUNKEN Semiconductors International will focus on Renesas Electronics’ current customers without interruption for the same high-quality level of production and service at the Roseville facility.
