SMG's year-end analysis of the silicon wafer industry reported that silicon shipments totaled 12,407 million square inches (MSI), compared to the11,810 MSI shipped in 2019, a rebound in volume of 5% year over year, recovering close to the historic high set in 2018.
“2020 silicon wafer shipment growth was driven by healthy 300mm demand and a strong second half of 2020 despite disruptions to the semiconductor industry caused by COVID-19,” said Neil Weaver, chairman SEMI SMG and vice president, Product Development and Applications Engineering at Shin Etsu Handotai America.
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.
The SMG is a sub-committee of the SEMI Electronic Materials Group (EMG) whose members are involved in manufacturing polycrystalline silicon, monocrystalline silicon or silicon wafers (e.g., as cut, polished, epi).
