ASML’s planned capacity expansion is easing concerns that lithography equipment could constrain the next phase of artificial-intelligence semiconductor growth. The Dutch supplier said it intends to raise production capacity by 30% in each of the next two years, responding to strong demand from leading-edge logic and memory manufacturers.
ASML is the sole supplier of extreme-ultraviolet lithography systems, which are required to pattern the smallest features in advanced processors and high-bandwidth memory. Limited EUV availability can therefore delay fabrication-plant ramps at customers such as TSMC, Samsung, and Intel, indirectly restricting supplies of AI accelerators.
The expansion combines additional assembly capability, supplier investments, and productivity improvements across ASML’s EUV and deep-ultraviolet platforms. Its EUV order book is close to fully allocated through 2027, indicating that customers are reserving equipment well before fabrication capacity becomes operational.
ASML also raised its 2026 revenue forecast to €43–45 billion after second-quarter revenue reached €9.33 billion and net income totaled €2.92 billion. Higher system volumes should improve equipment availability, but bottlenecks may persist in optics, light sources, advanced packaging, power infrastructure, and skilled labor.
The upgrade reduces one supply-chain risk; however, sustained AI-chip output still depends on synchronized expansion across wafer fabrication, memory, packaging, and data-center infrastructure.
