U.S. Investigates Potential Unauthorized Transfer of ASML EUV Lithography Technology to China

The U.S. Department of Commerce is investigating allegations that ASML extreme ultraviolet (EUV) lithography equipment reached China, potentially bypassing export controls. While ASML denies the claim and no public evidence exists, the incident highlights the strategic risk of China attempting to reverse-engineer advanced semiconductor manufacturing hardware. The extent of any potential technology leakage remains unverified.
