ASML

The world's only mass producer of EUV lithography equipment and a key bottleneck company in the semiconductor equipment industry, headquartered in Veldhoven, the Netherlands

ASML

Overview

ASML (Advanced Semiconductor Materials Lithography) is a semiconductor lithography equipment manufacturer headquartered in Veldhoven, the Netherlands, and the only company in the world capable of mass-producing extreme ultraviolet (EUV) lithography equipment. As it occupies what is effectively the sole bottleneck point in advanced semiconductor patterning, the production roadmaps of all leading-edge foundries and memory manufacturers — including TSMC, Samsung Electronics, and Intel — are directly or indirectly dependent on ASML's equipment shipment schedules. As of 2024, its market capitalization ranks at the very top among European tech companies, and it is dual-listed on the Amsterdam Stock Exchange (ASML) in the Netherlands and on the US Nasdaq (ASML).

History and Founding Background

ASML began in 1984 as a 50:50 joint venture between the Dutch electronics giant Philips and the semiconductor equipment distributor ASM International. Its market share was insignificant at first, but in the early 2000s, through collaboration with Taiwan's TSMC, it commercialized immersion lithography technology and rose to first place, overtaking Japan's Nikon and Canon. Since the mid-2000s it has invested billions of euros in developing EUV light source technology, and from around 2018 it began mass-producing and shipping EUV equipment in earnest.

Core Technology: EUV Lithography

Lithography is the process of printing circuit patterns onto a wafer using light, and it is the core of semiconductor miniaturization. Conventional DUV (deep ultraviolet, 193nm wavelength) had limits in forming patterns below 7nm due to wavelength constraints. ASML's EUV equipment uses extreme ultraviolet light with a 13.5nm wavelength; to produce it, tin plasma is exploded at ultra-high temperatures in a vacuum chamber to generate EUV light, which is then reflected and focused by ultra-precision multilayer mirrors. Because reflective mirrors are used instead of lenses, the entire optical system requires unrivaled precision. A single machine costs hundreds of billions of won, weighs hundreds of tons, and contains hundreds of thousands of parts.

Product Lineup

  • TWINSCAN series: The basic platform for the DUV (ArF, KrF) and EUV lineups. Dual wafer stages boosted productivity.
  • NXE series: 0.33 NA (numerical aperture) EUV equipment. Used for 7nm–3nm-class processes.
  • EXE series (High-NA EUV): Next-generation EUV equipment achieving 0.55 NA. It handles sub-2nm processes and 3D stacked structures. The price per unit is known to be around 500 billion won.
  • Metrology & Inspection: It also supplies metrology and inspection equipment, supporting process yield management.

Supply Chain and Ecosystem

ASML does not make every component itself. Germany's Carl Zeiss supplies the reflective mirrors and optical system for EUV, TRUMPF supplies CO2 laser light source components, and Cymer is exclusively responsible for the EUV light source. The Dutch government controls the export of advanced equipment such as EUV to China, which, combined with US export control policy, acts as a geopolitical variable.

Major Customers

  • TSMC: A first-generation EUV customer, adopting it in large volumes for 7nm, 5nm, 3nm, and 2nm processes.
  • Samsung Electronics: Applies EUV to foundry and memory (DRAM 1a·1b·1c) processes.
  • Intel: The first customer to introduce High-NA EUV, along with its transition to the 18A/14A processes.
  • SK Hynix and Micron: Used for DRAM fine processes and expanded HBM production.

Latest Trends

In 2024–2025, ASML is moving around the full-scale shipment of High-NA EUV (EXE:5000/5200) equipment and the transition to the 2nm generation. Intel introduced High-NA equipment and began developing its 14A process, while Samsung Electronics and TSMC are coordinating their introduction schedules. On the other hand, as the share of sales to China plunged due to tightened export controls (from the 40% range at one point in 2024 to the 20% range), the regional composition of revenue was reorganized, and in 2025, stock price volatility expanded due to tariffs, trade disputes, and a slowdown in the memory investment cycle.

Technically, while the debate over economic viability continues amid the increasing size and cost of High-NA, ASML is pursuing next-generation light source and stage technologies aimed at the era after "Hyper-NA," as well as expanding its equipment lineup for advanced packaging (hybrid bonding). In addition, as the explosive demand for AI semiconductors stimulates investment in HBM and leading-edge logic, expectations are forming for an order recovery after 2026.

In Korea, it operates the ASML Korea campus and remanufacturing and training facilities in Hwaseong and Icheon, and cooperation with Samsung Electronics and SK Hynix is strengthening. Maintenance and parts supply for lithography equipment also act as entry barriers, so ASML's competitive advantage extends beyond simple equipment sales to the entire service ecosystem.
