Bookmark and Share


SAN JOSE, Calif. –August 4, 2009Worldwide silicon wafer area shipments increased significantly during the second quarter 2009 when compared to the first quarter 2009 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 1,686 million square inches during the most recent quarter, a 79 percent increase from the 940 million square inches shipped during the previous quarter. The new quarterly total area shipments are 27 percent below second quarter 2008 shipments.

"Silicon wafer shipments recovered sharply from the low levels reported in the first quarter, though remain well below last year’s shipments,” said Nobuo Katsuoka, chairman of SEMI SMG and director, SOI process Engineering Department for Shin-Etsu Handotai Co., Ltd. ”The recovery in wafer shipments is inline with general trends reported elsewhere in the semiconductor industry.”

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 Austin, Bangalore, Beijing, Brussels, Hsinchu, Moscow, San Jose, Seoul, Shanghai, Singapore, Tokyo, and Washington, D.C. For more information, visit
