MILPITAS, Calif. & HSINCHU, Taiwan – May 9, 2026 – The global semiconductor wafer industry is witnessing a robust recovery driven by surging demand from artificial intelligence (AI) applications, with key indicators showing significant year-on-year growth in shipments and a tightening supply landscape for advanced 12-inch wafers, according to recent reports from SEMI and industry leaders.
SEMI’s Silicon Manufacturers Group (SMG) announced on April 29 that worldwide silicon wafer shipments increased 13.1% year-on-year to 3,275 million square inches (MSI) in the first quarter of 2026, up from 2,896 MSI in the same period last year. Sequentially, shipments declined 4.7% from the 3,437 MSI recorded in Q4 2025, a dip attributed to typical seasonal fluctuations rather than weakening demand.
“Silicon wafer demand related to AI data centers continues to be strong, including advanced logic and memory, and also now extending to power management devices,” noted Ginji Yada, Chairman of SEMI SMG and Managing Executive Officer at Sumco Corporation. He added that while overall demand has improved, the recovery is not uniform, with industrial semiconductor segments showing promising growth as wafer inventory is gradually absorbed, offsetting weaker smartphone and PC shipments impacted by tight memory supply due to AI-related HBM allocation decisions.
Industry giant GlobalWafers echoed this optimistic outlook, outlining its 2026 recovery path on May 6 and highlighting a tightening supply of 12-inch wafers amid rising AI-driven demand. The company expects the current semiconductor cycle to bottom out in Q1 2026, with the speed and breadth of recovery exceeding prior expectations, as AI continues to drive growth across the entire industry.
The strong growth in wafer shipments is closely tied to the expansion of advanced process nodes and the rising adoption of 12-inch wafers, which are critical for high-performance AI chips, cloud infrastructure, and memory devices. According to industry analysis, 12-inch wafer capacity is projected to grow at a compound annual growth rate (CAGR) of 10.4% between 2021 and 2030, with China emerging as a key growth driver, contributing 30% to 40% of global semiconductor equipment revenue and boasting a CAGR of 21.4%—significantly higher than the 6.2% average in non-Chinese markets.
Meanwhile, capacity utilization for 12-inch wafers is expected to improve throughout 2026, with major manufacturers including Jinghe Integrated, Powerchip, and SMIC projected to reach utilization rates of 93%, 91%, and 90% respectively by Q4, driven by strong domestic and global demand. In contrast, 8-inch wafer capacity growth remains sluggish, with a CAGR of only 1.2% during the same period, as manufacturers shift resources to higher-value 12-inch production lines.
The industry’s recovery is also supported by significant capital expenditures from leading foundries, particularly TSMC, which is expected to invest $47.708 billion in 2026—up 18% year-on-year—primarily for advanced process R&D, advanced packaging capacity expansion, and global manufacturing base construction. This investment will further reinforce TSMC’s dominance in the advanced process segment, where its 3nm yield exceeds 80%, far outpacing competitors like Samsung, whose 3nm yield remains around 30%.
Looking ahead, industry experts anticipate that AI-driven demand will continue to be the primary growth engine for the semiconductor wafer market, with advanced logic and memory segments leading the expansion. However, challenges remain, including uneven recovery across market segments and potential supply constraints for critical wafer sizes. As manufacturers ramp up capacity and technology innovation, the global semiconductor wafer industry is poised for a broader and more sustainable recovery in the coming quarters.
