Lithography systems

Why the concentration exists

Patterning systems project circuit designs onto photoresist-coated wafers, setting the resolution ceiling for every process node in semiconductor manufacturing. EUV systems work at a wavelength of 13.5 nm, generated by firing laser pulses at tin droplets vaporized 50,000 times per second. Modern wafer stages accelerate at up to 7 g while sensors measure position 20,000 times per second at 60 picometer accuracy, which is why lithography is a capital-intensive balancing act between wavelength, numerical aperture, and overlay precision.[1][8][9][12]

ASML is the only company capable of manufacturing extreme ultraviolet lithography machines anywhere in the world. This sole-source position stems from the layered physics, capital, and qualification barriers stacked above one another: a tin-droplet laser-produced plasma light source, the most precise mirror optics ever mass-produced, and a customer base that must qualify each tool for high-volume production over months. The result is a market structure in which a single node's resolution ceiling is set by one Dutch company's annual run rate.[2][3][4][6]

What the evidence shows

Who supplies it

Carl Zeiss Semiconductor Manufacturing Technology is the sole supplier of lenses, mirrors, illuminators, collectors, and other critical optical components for ASML's EUV tools under an exclusive arrangement. ASML's own 2025 annual report states that lithography tool output is directly limited by Zeiss SMT's production capacity. Zeiss is currently adding approximately 25,000 square meters of production and production-adjacent space at Oberkochen, Germany, with the first building completed in July 2026.[5][8]

Other lithography vendors play a much narrower role: Nikon has delivered more than 10,000 lithography systems across semiconductor and flat-panel display applications over 45 years, while Canon has not released a new DUV tool since 2012. China's Shanghai Micro Electronics Equipment (SMEE) holds only about 4% of the global market in i-line equipment used for legacy chips. ASML draws from over 5,100 unique suppliers and spent more than €15.5 billion annually with those suppliers in 2023.[7][10][11][15]

Where it sits in the stack

What to watch

ASML's next-generation Low-NA Twinscan NXE:4000F system with throughput above 250 wafers per hour is due in 2027, followed by the NXE:4200G with above 280 wph in 2029, and a 1000 W EUV power source capable of up to 330 wph is projected for 2030 or beyond. ASML raised its 2026 annual revenue forecast from €36-40 billion to €43-45 billion. The Twinscan EXE:5000 High-NA platform supports high-volume chip manufacturing in 2025-2026, with mass production from the first imec-ASM unit expected in 2025 and Intel's separate order dating to 2018.[6][8][13][17]

Shanghai Yuliangsheng Technology's domestic immersion DUV tool has been under testing at SMIC since September 2025, with active mass production at SMIC targeted as early as 2027. Hangzhou's state-backed firm has announced Xizhi, an electron-beam lithography machine claiming 0.6 nm precision and 8 nm line width, now entering application testing. Intel reported producing 30,000 wafers in a quarter using ASML's High-NA EUV machine, while TSMC's A16 and A14 nodes are designed to operate without High-NA EUV.[7][14][16][17]
