ASML EUV Machines: US Suspects Smuggling to China, Calls Claims Baseless

US officials suspect ASML smuggled EUV lithography machines to China, raising serious concerns about semiconductor supply chain security. The Commerce Department questioned ASML executives about potential export control violations, signaling a high-stakes regulatory investigation. This scrutiny matters because EUV tools are critical for advanced chip manufacturing, and any unauthorized transfer could disrupt global tech operations.

ASML denies US allegations regarding EUV lithography machine exports

ASML, a Dutch semiconductor equipment manufacturer, produces the extreme ultraviolet lithography systems involved in the allegations. These machines weigh 180 tons each and require specialized transport systems to move between fabrication facilities. The company states it strictly follows all applicable laws, including the Wassenaar Arrangement, which bans EUV deliveries to China.

EUV Lithography Machine Facts

• Total EUV Units in Use: 314
• Retired EUV Units: 26
• Machine Weight: 180 tons
• Location in Mainland China: None

ASML reports that 314 EUV units are currently in use globally, with 26 retired. The company asserts that none of these active machines are located in mainland China. ASML claims backend connectivity tracks every unit, ensuring compliance with export restrictions. US officials acknowledge they have clues but refuse to disclose specific evidence due to sensitivity.

ASML calls the allegations baseless and says they have a highly negative impact on the company. The firm emphasizes its commitment to legal compliance in all business operations. This dispute highlights the tension between advanced technology access and international trade regulations. The matter is under investigation by US authorities who are examining the evidence.

The investigation focuses on whether ASML violated export controls by transferring EUV-related components. ASML maintains that all its activities adhere to international agreements. The resolution of this case will demonstrate the enforcement of export control regulations regarding semiconductor technology. Industry stakeholders are monitoring the situation for potential impacts on global semiconductor supply chains.
