2020 Global Silicon Revenue Remains Stable as Wafer Area Shipments Edge Up Despite COVID-19 Disruption MILPITAS, Calif., Feb. 2, 2021 /PRNewswire/ -- Worldwide silicon wafer area shipments in 2020 increased while revenue remained unchanged from 2019 at $11,170 million, the SEMI Silicon Manufacturers Group (SMG) reported in its year-end analysis of the silicon wafer industry. Silicon shipments totaled 12,407 million square inches (MSI), compared to 11,810 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.
