Worldwide silicon wafer area shipments increased during the third quarter of 2018, surpassing record second quarter 2018 area shipments to set another all-time high, according to the SEMI Silicon Manufacturers Group (SMG) in its quarterly analysis of the silicon wafer industry.

Total silicon wafer area shipments reached 3,255 million square inches during the most recent quarter, a 3 percent rise from the 3,164 million square inches shipped during the previous quarter. New quarterly total area shipments clocked in 8.6 percent higher than third quarter 2017 shipments.

“Silicon shipment volumes remained at record levels during the third quarter,” said Neil Weaver, chairman SEMI SMG and director, Product Development and Applications Engineering of Shin Etsu Handotai America. “Silicon shipments are mirroring this year’s strong semiconductor unit growth in support of a growing and diversified electronics market during our stable economy.”

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 to 12 in.) and serve as the substrate material on which most semiconductor devices, or chips, are fabricated.
