Silicon Wafer Shipments Flatten in Third Quarter 2007

Bookmark and Share


SAN JOSE, Calif. – November 6, 2007Total silicon wafer area shipments were 2,174 million square inches during the most recent quarter, up around 5 percent year-over-year yet essentially flat sequentially according to the SEMI Silicon Manufacturers Group (SMG) in its quarterly analysis of the silicon wafer industry. In total, wafer shipments seem to remain on track to see around 8 percent growth for the year.

"In line with the historic pattern, the pace of wafer area shipments has slowed slightly for the third quarter,” said Dr. Volker Braetsch, Chairman SEMI SMG and Corporate Vice President of Siltronic AG. ”This is the result of smaller area diameter wafer shipments declining while 300 mm wafer shipments continued to grow.”

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 1971, SEMI has been committed to helping members grow more profitably, create new markets and meet common industry challenges. SEMI maintains offices in Austin, Beijing, Brussels, Hsinchu, Moscow, San Jose, Seoul, Shanghai, Singapore, Tokyo, and Washington, D.C. For more information, visit
