EUV Lithography Powers the AI Chip Revolution

Key Takeaways

• Extreme ultraviolet (EUV) lithography uses 13.5‑nm light to etch billions of transistors, enabling all chips at 7 nm and below.
• ASML Holding is the sole manufacturer of EUV machines, giving it a near‑monopoly and making the EUV ecosystem a strategic chokepoint in the global tech supply chain.
• The EUV ETF concentrates on companies that design, build, supply, or use EUV technology, with ASML as the dominant holding and significant exposure to TSMC, Samsung, Applied Materials, Lam Research, JSR, and Shin‑Etsu Chemical.
• Rising investor interest is driven by exploding AI‑chip demand, geopolitical restrictions limiting ASML sales to China, and the “DRAM halo effect” that pushes investors toward the broader AI‑chip manufacturing ecosystem.
• Compared with broader semiconductor ETFs (SMH, SOXX) the EUV ETF offers a higher‑conviction bet on the equipment layer, while the DRAM‑focused ETF targets memory chips specifically; the two are complementary.
• The bull case hinges on the indispensability of EUV for every advanced chip and ASML’s unique position; risks include heavy concentration in ASML, sensitivity to semiconductor capex cycles, regulatory or trade‑policy shifts, and demand slowdowns at major customers like TSMC.
• Long‑term investors who believe in continued AI infrastructure expansion may view the EUV ETF as a way to gain direct exposure to the single most irreplaceable step in chip manufacturing.

What Is EUV Lithography?
Extreme ultraviolet lithography employs light with a wavelength of only 13.5 nanometers—about forty times shorter than visible light—to pattern silicon wafers with extraordinary precision. This process is the foundational step for producing transistors at the 7‑nanometer node and smaller, which includes virtually every high‑performance AI processor, smartphone system‑on‑chip, and modern data‑center accelerator. Without EUV, the density and performance gains that power today’s artificial‑intelligence revolution would be unattainable.

ASML’s Near‑Monopoly and Strategic Importance
ASML Holding (ASML) is the exclusive global supplier of EUV machines; each tool costs more than $200 million and incorporates components from over 5,000 suppliers spread across 30 countries. This near‑monopoly positions ASML—and the broader EUV ecosystem—as a critical choke point in the worldwide technology supply chain. Any disruption to ASML’s ability to deliver or service its machines would ripple through chip manufacturers, affecting everything from consumer electronics to AI infrastructure.

Holdings of the EUV ETF
The EUV ETF is constructed to give investors concentrated exposure to the entire EUV lithography value chain. Its typical portfolio includes:

• ASML Holding (ASML) – the sole maker of EUV scanners and the ETF’s largest weight.
• Taiwan Semiconductor Manufacturing Company (TSM) – the world’s leading foundry and the biggest consumer of EUV equipment.
• Samsung Electronics – the second‑largest EUV user, competing with TSMC at the most advanced process nodes.
• Applied Materials (AMAT) and Lam Research (LRCX) – adjacent semiconductor‑equipment firms that provide deposition, etch, and cleaning tools essential to EUV workflows.
• JSR Corporation and Shin‑Etsu Chemical – suppliers of photoresists and other specialty chemicals that enable the EUV patterning process.

By holding these companies, the ETF captures both the equipment layer (ASML, AMAT, LRCX) and the end‑users (TSMC, Samsung) plus critical material inputs.

Why EUV Is Trending Now
Three converging catalysts have propelled the EUV ETF into the spotlight:

1. Surging AI‑chip demand – Every cutting‑edge AI accelerator, from Nvidia’s Blackwell architecture to AMD’s MI300, relies on EUV lithography for manufacture. As AI‑infrastructure spending accelerates, the need for EUV capacity grows in tandem.
2. Geopolitical scarcity – The United States and its allies have restricted ASML from selling EUV machines to China, imposing a hard ceiling on China’s ability to produce leading‑edge semiconductors. This restriction frames EUV exposure as a bet on Western semiconductor supremacy, a theme that has resonated strongly with investors since 2022.
3. The DRAM halo effect – The DRAM‑focused ETF has experienced a +263.5 % increase in page views this month, prompting investors to explore the wider AI‑chip manufacturing ecosystem. EUV lithography is the enabling technology for both DRAM and logic chips at the leading edge, making it a natural next step for those seeking broader exposure.

How the EUV ETF Compares to Broader Semiconductor Funds

• Versus SMH (VanEck Semiconductor ETF) – SMH offers diversified exposure across more than 25 semiconductor holdings, spanning design, manufacturing, and equipment. The EUV ETF is far more concentrated, with a heavy weighting toward ASML, thus representing a higher‑conviction bet on the equipment layer rather than on chip designers or broad semiconductor markets.
• Versus SOXX (iShares Semiconductor ETF) – SOXX tracks an index of 30 U.S.–listed semiconductor companies. Because ASML is listed in the Netherlands, SOXX provides less direct EUV exposure than the EUV ETF itself, which holds ASML as a core position.
• Versus a DRAM‑focused ETF – While a DRAM ETF targets memory chips specifically, the EUV ETF addresses the manufacturing infrastructure that makes both DRAM and leading‑edge logic chips possible. The two funds are complementary: DRAM captures demand for memory, whereas EUV captures the underlying process that enables all advanced semiconductors.

The Investment Case for EUV
The bullish thesis is straightforward: every advanced chip fabricated at 7 nm or below requires EUV lithography, and ASML remains the only supplier capable of delivering the necessary machines. As AI continues to drive exponential demand for more powerful semiconductors, the strategic importance of EUV lithography intensifies rather than diminishes.

However, risks are non‑trivial. The ETF’s performance is heavily tied to ASML; any regulatory change, trade dispute, or slowdown in capital expenditures by major customers such as TSMC or Samsung could induce pronounced volatility. EUV tools are extraordinarily capital‑intensive, making the sector sensitive to the cyclical nature of semiconductor capex. Additionally, while current geopolitical restrictions benefit non‑Chinese suppliers, any shift in policy—such as a relaxation of export controls—could alter the competitive landscape.

For investors who maintain a long‑term conviction in the ongoing build‑out of AI infrastructure, the EUV ETF offers a unique avenue to gain direct exposure to the single most irreplaceable step in chip manufacturing: the extreme‑ultraviolet lithography process that enables the transistors powering tomorrow’s AI, mobile, and data‑center technologies.
