Slight Decline in First Quarter 2011 Silicon Wafer Shipments

Slight Decline in First Quarter 2011 Silicon Wafer Shipments

SAN JOSE, Calif. — May 10, 2011 — Worldwide silicon wafer area shipments decreased slightly during the first quarter 2011 when compared to fourth quarter 2010 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 2,287 million square inches during the most recent quarter, a 1 percent decrease from the 2,302 million square inches shipped during the previous quarter. New quarterly total area shipments are 3 percent greater than first quarter 2010 shipments.

"Silicon shipments experienced typical seasonal softening during the most recent quarter,” said Dr. Volker Braetsch, chairman of SEMI SMG and corporate vice president Siltronic AG. “Given that 2010 was a record year in terms of volume of silicon shipped, it is encouraging to see quarterly shipments were above levels reported the first quarter last year.”

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
