Increase in Second Quarter 2011 Silicon Wafer Shipments

SAN JOSE, Calif. – August 2, 2011 – Worldwide silicon wafer area shipments increased five percent during the second quarter 2011 when compared to first quarter 2011 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 2,392 million square inches during the most recent quarter, a five percent increase from the 2,287 million square inches shipped during the previous quarter. New quarterly total area shipments are one percent greater than second quarter 2010 shipments.

"Silicon shipments increased during the most recent quarter,” said Dr. Volker Braetsch, chairman of SEMI SMG and corporate vice president of Siltronic AG. “It is notable how well silicon suppliers were able to support the overall semiconductor industry in the immediate aftermath of the earthquake and ensuing tsunami in Japan.”

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 one inch to 12 inches) 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 related to the silicon industry including the development of market information and statistics about the silicon industry and the semiconductor market.

SEMI is the global industry association serving the manufacturing supply chains for the microelectronic, display and photovoltaic industries. SEMI member companies are the engine of the future, enabling smarter, faster and more economical products that improve our lives. Since 1970, SEMI has been committed to helping members grow more profitably, create new markets and meet common industry challenges. SEMI maintains offices in Beijing, Bengaluru, Berlin, Brussels, Grenoble, Hsinchu, Moscow, San Jose, Seoul, Shanghai, Singapore, Tokyo, and Washington, D.C. For more information, visit www.semi.org.
