SILICON WAFER SHIPMENT INCREASE IN THIRD QUARTER 2005

SAN JOSE, California, November 14, 2005—Worldwide silicon wafer area shipments increased 9 percent during the third quarter 2005 when compared to the second quarter area shipments according to the SEMI® Silicon Manufacturers Group (SMG) in its quarterly analysis of the silicon wafer industry.

Total silicon wafer area shipments were 1,748 million square inches during the most recent quarter, up from the 1,606 million square inches shipped during the previous quarter. The new quarterly total area shipments are 7 percent above third quarter 2004 shipments.

"The strength in silicon shipments exhibited in the second quarter of this year was followed by an even stronger third quarter,” said Makoto Tsukada, chairman SEMI SMG and general manager of Shin-Etsu Handotai Co., Ltd. "This upward momentum was driven not only by the increasing proportion of 300 mm wafers shipped but also by strong demand for 200 mm wafers.”

Silicon wafers are the fundamental building material for semiconductors, which in turn, are vital components of virtually all electronics goods, including computers, telecommunications products and consumer electronics. The highly engineered thin round disks are produced in various diameters (from 1 inch to 12 inch) and serve as the substrate material on which most semiconductor devices or "chips" are fabricated.

All data cited in this release is inclusive of polished silicon wafers, including virgin test wafers, epitaxial silicon wafers and non-polished silicon wafers shipped by the wafer manufacturers to the end-users.

The Silicon Manufacturers Group acts as an independent special interest group within the SEMI structure and is open to SEMI members involved in manufacturing polycrystalline silicon, monocrystalline silicon or silicon wafers (e.g., as cut, polished, Epi, etc.). The purpose of the group is to facilitate collective efforts on issues relating to the silicon industry including the acquisition of market information and statistics about the silicon industry and the semiconductor market.

SEMI is a global industry association serving companies that provide equipment, materials and services used to manufacture semiconductors, displays, nano-scaled structures, micro-electromechanical systems (MEMS) and related technologies. SEMI maintains offices and hosts programs and activities in every major microelectronics and display manufacturing region around the world. For more information, visit www.semi.org.
