ASML, headquartered in Veldhoven in the Netherlands, makes the lithography machines that chipmakers use to print circuit patterns onto silicon wafers. It describes itself as the world's only manufacturer of extreme ultraviolet (EUV) lithography systems, the machines used for the most critical layers of the most advanced chips, and it also makes the older deep ultraviolet (DUV) machines that print most other layers. Founded in 1984 as a venture between Philips and ASM International, ASML had 2025 net sales of 32.7 billion euros and employs more than 44,500 people. Its customers are the world's leading chipmakers; its largest single customer bought 23.9 percent of its 2025 sales.
Arizona has been part of ASML's story for more than 25 years. Its North American headquarters was in Tempe, where it opened a $72 million training center in the ASU Research Park in 2002. It moved its corporate office to Chandler around 2013 and to its current building at 2625 W. Geronimo Place in 2021, and its 2025 annual report names Chandler as its U.S. head office. Chandler is also the U.S. hub of ASML's Global Support Center, one of three sites that give round-the-clock support to the company's field engineers worldwide. ASML employs about 700 people in Arizona, many of them engineers stationed inside the region's fabs.
Those fabs are its customers. ASML says nearly 150 of its customer support engineers in Chandler serve Intel, whose Fab 52 there makes Intel 18A processors; reporters touring Fab 52 in 2025 saw ASML EUV machines at the heart of the building. For TSMC, ASML built up a Phoenix office in 2022, 15 minutes from TSMC's new fab, reaching 140 staff and sending more than 100 engineers to Taiwan to train. The relationships run deep: ASML says it shipped its first EUV prototype and first production-ready EUV system to TSMC, and in 2012 Intel, TSMC and Samsung bought stakes in ASML and committed 1.38 billion euros to its EUV and 450 mm research.
In November 2025 ASML inaugurated its U.S. Technical Training Academy at 1717 E. Grant St. in Phoenix, near Sky Harbor airport. The 56,000-square-foot academy began training engineers in 2024 and is the only ASML site in the country that trains engineers across all of its product lines. ASML expects it to train more than 1,000 engineers a year, eventually 2,000, and other chipmakers can pay to train their own engineers there.
ASML ties its current growth to artificial intelligence. In July 2026 its chief executive said AI-related investment is driving demand for advanced logic and memory chips, and the company raised its 2026 sales outlook to between 43 and 45 billion euros. Its newest High-NA EUV machines are in volume production at Intel on select layers of some 18A chips, and TSMC plans to use them in high-volume manufacturing from 2030.
The company also faces real constraints. Dutch export rules since 2023 require licenses for its most advanced DUV machines, China's share of its sales fell from 36.1 percent in 2024 to 29.1 percent in 2025, and a bill in Congress would require U.S. licenses for exports of DUV immersion machines to China and bar servicing at designated advanced Chinese fabs. In January 2026 ASML proposed cutting about 1,700 net positions, mostly in the Netherlands and some in the United States. Arizona AI found no Arizona-specific layoff notice, lawsuit or incentive award involving ASML as of September 2026.
