The US government suspects that ASML's most advanced chipmaking tool, the High-NA EUV lithography system, may have ended up in China despite export restrictions. ASML denies this, stating it has not shipped any such systems to Chinese customers. The tool, which costs over $350 million, is critical for manufacturing cutting-edge semiconductors. US officials cite intelligence reports, but ASML insists its compliance protocols are robust.
This is a high-stakes game of he-said-she-said. The US sees a ghost. ASML sees a threat to its reputation. Let's look at the logic. ASML's High-NA EUV is a monopoly product. The company holds all the cards. Selling one to China would be like a baker giving away the secret recipe. It would risk export licenses and invite sanctions. Why would they do that? The commercial incentive is zero. The risk is everything.
China wants that tool badly. They need it to compete with TSMC and Samsung. But ASML has everything to lose. The US has a history of overreach. Remember the Huawei ban? Sometimes the intelligence is wrong. I think ASML is telling the truth. The real story is how scared the US is of Chinese chip progress. That fear drives suspicion. But facts matter. And the fact is: no High-NA EUV has crossed the Pacific.
