ASML's EUV Lithography Technology Faces Challenges in China Amid U.S. Concerns
The U.S. Department of Commerce has raised concerns about the potential transfer of ASML's extreme ultraviolet (EUV) lithography technology to China. ASML, the sole global producer of these advanced machines, denies any such transfer. The U.S. fears that China could gain significant technological insights if it obtains access to these machines or their components. Despite these concerns, replicating the complex technology remains a significant challenge due to the intricate systems integration and the specialized knowledge required, which is accumulated over decades by ASML and its suppliers.
