Quick answer
ASML Holding N.V. is the world's sole manufacturer of EUV (extreme ultraviolet) lithography systems, the machines that print circuit patterns at the most advanced semiconductor process nodes. Without ASML's EUV systems, TSMC, Samsung and Intel Logic cannot manufacture their most advanced chips. ASML also produces DUV (deep ultraviolet) lithography systems with a broad installed base across global chip makers. ASML is incorporated in the Netherlands and trades on Nasdaq as an ADR (ticker: ASML), and is a member of the SOX index.
The central research question: Can ASML convert its near-indispensable lithography position into durable growth while customers absorb rising tool complexity, cost and geopolitical restrictions?
Investor takeaway: ASML's EUV monopoly gives it pricing power that no other semiconductor equipment company possesses. That same concentration creates meaningful exposure to semiconductor capital expenditure cycles, and the evolving export control regime around China introduces ongoing policy risk to the DUV revenue line. Investors should weigh monopoly position, cycle exposure and export control risk together when evaluating ASML.

What ASML sells
ASML is the only manufacturer of EUV lithography systems in the world. These machines use extreme ultraviolet light at a wavelength of 13.5 nanometers, generated by firing high-powered lasers at tiny tin droplets to create plasma that emits EUV radiation, to expose circuit patterns onto silicon wafers with extraordinary precision. A single EUV system contains over 100,000 components, occupies a space the size of a double-decker bus, costs roughly 200 million euros or more, and requires a specialized cleanroom environment. TSMC, Samsung Foundry and Intel Logic are the only current EUV customers, as EUV is required only for the most advanced logic process nodes (7nm and below in commercial volume). High NA EUV, the next-generation system using higher numerical aperture optics, is ASML's technology roadmap for sub-2nm nodes and carries an even higher cost per system.
ASML's DUV product line covers ArF immersion (the most advanced DUV), ArF dry and KrF tools, used across a much broader range of process nodes (from roughly 10nm down to 40nm and mature nodes like 90nm, 130nm, 180nm). DUV customers include memory makers (DRAM and NAND flash manufacturers), foundries serving automotive and industrial customers, and mature-node logic producers. DUV systems are lower cost per unit than EUV but sell in larger volumes and to a wider customer base. Nikon and Canon compete in DUV, but ASML has dominant market share in advanced DUV (ArFi) as well as in EUV.
ASML has installed approximately 7,000 or more systems globally. This installed base generates recurring revenue from service contracts, spare parts, field upgrades and refurbishment. Service revenue is higher-margin and less cyclical than new system sales, providing earnings stability through the semiconductor equipment cycle. Metrology and inspection tools (through subsidiary HMI/Hermes Microvision) complement the lithography business by allowing customers to verify pattern quality on wafers as they move through the fabrication process.
The EUV monopoly position
No other company manufactures EUV lithography systems because building one required multiple decades of R&D, substantial government and customer co-investment, and the assembly of a unique global supply chain. TSMC, Samsung, Intel and others invested directly in ASML during its EUV development phase, sharing the financial risk in exchange for early access. The technology depends on specialized optics from Carl Zeiss SMT, pulsed laser systems from TRUMPF, and hundreds of additional suppliers whose collective capabilities were assembled over years into a system no single company could replicate from scratch today. The physics of generating usable EUV light from tin plasma, then directing and focusing it through multilayer reflective mirrors to a wafer with nanometer precision across an enormous mechanical system, represents an engineering challenge at the boundary of what materials science and precision manufacturing can achieve.
The practical implications for investors follow directly from this monopoly. Every advanced chip fab in the world must buy from ASML or forgo leading-edge chip production. This pricing power is reflected in EUV average selling prices that have risen with each system generation and will rise further with High NA EUV. Customer dependency, however, runs in both directions. ASML depends on a small number of very large customers: TSMC alone has accounted for roughly 30 to 40 percent of ASML revenue in some years. A pause or pullback in TSMC's leading-edge expansion plans flows directly into ASML's order intake and eventually its revenue, which is why monitoring TSMC's capital expenditure guidance is a central part of any ASML research process.
Export controls and China
ASML has never been permitted to export EUV lithography systems to Chinese customers. The Dutch government requires an export license for each EUV system, and these licenses have not been granted for shipments to China. This means Chinese chip makers including SMIC, Hua Hong and CXMT cannot manufacture chips at leading-edge nodes, regardless of what other resources they command. The EUV restriction is a hard ceiling on Chinese semiconductor capability at advanced nodes and has been in place since before EUV entered commercial production, so it does not represent a recent change in ASML's business model for that product line.
The DUV picture is more recent and more uncertain. Starting in 2023, the Dutch government responded to U.S. diplomatic pressure by imposing additional restrictions on ASML's ability to export certain DUV systems to China, specifically ArF immersion tools used for the most advanced DUV process nodes. China was historically a significant DUV customer for ASML, and these restrictions have reduced ASML's addressable revenue from that market. The evolving export control environment creates ongoing uncertainty about the China DUV business: the scope of restrictions could narrow or widen depending on Dutch and EU policy decisions and U.S. diplomatic engagement. Investors should monitor export control policy changes as a material ongoing risk factor for the DUV revenue line, distinct from the EUV prohibition which has been stable for years.
Semiconductor equipment cycle
ASML's revenue follows the semiconductor capital expenditure cycle, with a lead time of 18 to 24 months between order and delivery for EUV systems. When TSMC commits to a new leading-edge fabrication facility, ASML receives orders. When foundry expansion plans slow, order intake falls and backlog coverage decreases. The backlog is therefore a leading indicator of ASML's revenue outlook, and quarterly order intake (bookings) relative to revenue tells investors whether the backlog is growing, stable or declining. ASML's backlog has at times extended to multi-year coverage, reflecting the long lead time for EUV system delivery and the difficulty of rapidly scaling production of the most complex machines in the semiconductor supply chain.
DUV demand is more correlated with the broader memory and mature-node logic capex cycle, which tends to move faster and more sharply than leading-edge logic. Memory makers (DRAM and NAND flash) cut capital spending significantly in 2022 and 2023 when end markets weakened, reducing DUV order intake sharply before recovering. The combination of a slow-moving leading-edge logic cycle (driven by TSMC, Samsung and Intel's multi-year fab construction timelines) and a faster-moving memory cycle (driven by shorter supply-demand cycles in DRAM and NAND) means ASML's two main revenue streams can move in different directions at the same time, complicating single-metric cycle analysis.
Valuation framework
ASML is best understood through two revenue streams with different economics: new system sales (capital equipment, lumpy and cyclical) and installed base services (recurring, higher-margin, growing steadily with the installed base). The service stream has characteristics of a recurring revenue business: customers under service contract tend to renew, the installed base grows with each additional system shipped, and field upgrades can extend the revenue life of existing tools over many years. Valuing these streams separately and then applying a cycle-normalized multiple to system sales is more informative than applying a single blended multiple to total revenue, because the service stream deserves a higher multiple for its recurring characteristics while the system sales line requires adjustment for where the capex cycle stands.
EUV system average selling prices have risen with each generation, reflecting more content, more manufacturing complexity and more value delivered to customers. High NA EUV systems carry higher prices still. ASP expansion combined with unit volume growth is a powerful compound earnings driver if leading-edge capex remains robust over the long term. The risks to this thesis are concrete: a major delay in High NA EUV adoption by lead customers, a prolonged pause in leading-edge capex (as occurred in 2022 to 2023 when memory manufacturers cut spending sharply), permanent loss of China DUV revenue to export restrictions, or a geopolitical disruption affecting TSMC's Taiwan operations that interrupted leading-edge chip production globally. Investors modeling ASML should stress-test across a range of leading-edge fab construction scenarios and High NA adoption timelines rather than assuming a single central path.
Frequently asked questions
What does ASML make?
ASML designs and manufactures photolithography systems used by semiconductor chip makers to pattern circuits onto silicon wafers. ASML is the sole manufacturer of EUV (extreme ultraviolet) lithography systems, which are required to produce chips at the most advanced process nodes (7nm and below). ASML also produces DUV (deep ultraviolet) lithography systems used across a wider range of process nodes and customers. Both product lines are sold to leading chip manufacturers worldwide.
What is EUV lithography?
EUV (extreme ultraviolet) lithography is a chip-manufacturing technique that uses extreme ultraviolet light (wavelength of 13.5 nanometers) to print extremely fine circuit patterns onto silicon wafers. EUV enables chip makers to produce transistors at the most advanced nodes (5nm, 3nm, 2nm and below) with fewer manufacturing steps than older DUV techniques. ASML is the only company in the world that manufactures EUV lithography systems, making it an indispensable supplier to every leading-edge chip manufacturer including TSMC, Samsung Foundry and Intel Logic.
Is ASML in SOX?
Yes. ASML Holding N.V. (Nasdaq: ASML) is a member of the Philadelphia Semiconductor Index (SOX). ASML is incorporated in the Netherlands and listed on Nasdaq as an ADR (American Depositary Receipt). The SOX index includes non-U.S. issuers listed on U.S. exchanges as ADRs, and ASML's inclusion reflects its critical role in the global semiconductor supply chain. ASML is also a member of the Nasdaq-100 and the EURO STOXX 50 index.
What is ASML's competitive moat?
ASML's competitive moat in EUV lithography is near-absolute: no other company manufactures EUV systems. The technology requires extreme ultraviolet light generated by tin plasma struck by high-powered lasers, multilayer mirrors with sub-nanometer precision, complex mask infrastructure and a supply chain involving hundreds of specialized suppliers worldwide including Carl Zeiss (optics) and TRUMPF (lasers). Decades of R&D investment and the assembled supplier ecosystem make it practically impossible for a new competitor to replicate the capability within any near-term planning horizon.
How do export controls affect ASML?
Export controls have had significant impact on ASML's China business. ASML has never been permitted to export EUV systems to China. Starting in 2023, Dutch export controls (under U.S. pressure) also restricted export of certain DUV lithography systems, specifically ArF immersion tools, to Chinese customers. China was historically a significant DUV customer, and the restrictions have reduced ASML's revenue from that market. The controls do not affect ASML's EUV business with its primary customers (TSMC, Samsung, Intel Logic), because EUV was already prohibited for China before the DUV restrictions took effect.
