Hiroshima Elpida Commences Mass Production of 90 nm DRAM Chips on New 300 mm Wafer Production Line; Newly Expanded E300 Fab Targets 54,000 Wafers per Month, the Largest Semiconductor Capacity in Japan

HIROSHIMA, Japan—(BUSINESS WIRE)—Dec. 1, 2005— Elpida Memory, Inc. (Elpida) and Hiroshima Elpida Memory, Inc. (Hiroshima Elpida) announced today the completion of its new 300 mm production line at its 300 mm wafer fabrication facility (E300 Fab) in Hiroshima, Japan. The monthly 300 mm wafer production volume is expected to reach a capacity of 54,000 by FY Q4, which would make Hiroshima Elpida's E300 Fab the largest semiconductor wafer processing capacity in Japan.

Hiroshima Elpida began construction of a new facility to house the expanded line in June 2004. As scheduled, construction was completed in June 2005, and was followed by the installation of clean rooms and production equipment, as well as several test-runs of factory operations. In FY Q2, the E300 Fab started an average of 30,000 wafers per month. In November 2005, the E300 Fab handled 45,000 wafers per month, and during December 2005, volume is expected to increase to 50,000 wafers per month. Wafer output will likely contribute to shipments starting in 4Q of the current fiscal year ending March 31.

"Our first lot of wafers for mass production of DRAM using advanced 90 nm process technology started on October 17, 2005," said Shuichi Otsuka, president of Hiroshima Elpida. "Our initial ramp has been extremely smooth and successful, and each day we are seeing an increase in the number of wafers processed."

Production yield based on Elpida's 90 nm process technology has been outstanding since the start of mass production, and Elpida intends to have advanced 90 nm process technology account for approximately 70% of total monthly production at the E300 Fab within this fiscal year. Given the synergistic benefits from increased production at E300 and from the migration to 90 nm process, Elpida's shipment volumes during the first half of FY 2006 now have the ability to increase significantly. As a result, Elpida is well-positioned to provide a steady supply of DRAM products to the market in support of greater demand for memory.
