US presses ASML over fears a banned chip tool reached China
What's new: ASML denied any EUV machine or specially designed EUV parts were ever shipped to China.
The US has raised concerns with ASML that one of the Dutch company’s most advanced chipmaking tools may have ended up in China despite export curbs, according to a Bloomberg report cited by Reuters. US Commerce Secretary Howard Lutnick conveyed the concern in meetings with senior ASML executives. ASML rejected the claim, saying it has never sent an extreme ultraviolet, or EUV, machine to China and has not shipped any component or equipment specially designed for those systems there. The dispute touches one of the most sensitive choke points in the US-led effort to limit China’s access to top-tier semiconductor manufacturing technology.
