China could reproduce ASML technologies

An X post by user vidalnext on May 20 argued that China’s power generation and industrial base could allow it to reproduce advanced semiconductor manufacturing technologies associated with ASML. The post used the word “unstoppable” and tied that claim to China’s scale in electricity and manufacturing. The argument touches a live fault line in the chip industry, where ASML remains the only supplier of extreme ultraviolet, or EUV, lithography systems and where the Netherlands has tightened export controls on advanced tools to destinations outside the European Union. ### What exactly was the claim in the X post? The May 20 post by vidalnext framed China’s advantage as one of industrial capacity rather than a single laboratory breakthrough. The core claim was that a country with enough power generation, manufacturing depth and engineering capacity could eventually reproduce highly complex semiconductor equipment, including technologies associated with ASML. The post described that possibility as making China “unstoppable.” (asml.com) The claim is broader than a verifiable announcement of a finished Chinese alternative to ASML’s most advanced systems. No official filing from ASML, the Dutch government or a Chinese regulator reviewed here said China had reproduced ASML’s EUV platform. ### Why does ASML sit at the center of this debate? ASML says it is a leading supplier of lithography systems used to mass produce semiconductor chips, and its 2025 annual report highlights a portfolio spanning EUV, deep ultraviolet, or DUV, and metrology products. (x.com) The company reported 2025 net sales of 32.7 billion euros, research and development spending of 4.7 billion euros, more than 44,000 full-time employees and 5,100 suppliers. (asml.com) ZEISS and Cymer illustrate how distributed that technology base is. ZEISS says its Semiconductor Manufacturing Technology unit supplies the lithography optics used in wafer scanners in partnership with ASML, while ASML says Cymer develops light-source technology used in lithography systems. Those disclosures show that an ASML-class tool depends on optics, lasers, software, precision motion systems and a global supplier base rather than a single component. (asml.com) ### What do the current export controls actually cover? The Dutch government said on September 6, 2024 that it expanded national export controls on advanced semiconductor manufacturing equipment, making more systems subject to authorisation from September 7, 2024. Minister Reinette Klever said the measure was taken for security reasons and that applications would be assessed case by case rather than through a blanket export ban. (zeiss.com) ASML said the updated rules require export licenses for shipments of its TWINSCAN NXT:1970i and 1980i DUV immersion systems, while TWINSCAN NXT:2000i and later DUV immersion systems were already subject to license requirements. ASML also said sales of its EUV systems are subject to license requirements. ### Does China have the industrial scale the post points to? (government.nl) China’s official planning target for 2025 put total electricity generation at 10.6 trillion kilowatt-hours, according to a Chinese government report citing the National Energy Administration. Separate Chinese official data said renewable energy accounted for more than 60% of installed power generation capacity in 2025. (asml.com) Those figures support the narrow point that China has enormous energy and industrial scale. They do not by themselves establish that China can replicate the full performance of ASML’s most advanced lithography systems, which depend on tightly integrated supply chains and specialized subsystems developed over decades. That is an inference from the structure of ASML’s supplier network and partner disclosures, not a statement made by ASML itself. (english.gov.cn) ### What is the clearest fact to watch next? ASML’s next public signals will come through its investor disclosures and any Dutch licensing decisions affecting shipments to China. The Dutch government’s export-control regime remains in place, and ASML’s annual and quarterly reports remain the clearest public record of how much China contributes to sales, service revenue and installed-base activity.
