Intel Corp‘s (NASDAQ:INTC) manufacturing comeback may have just crossed its biggest checkpoint yet—and it isn’t about a new processor. Instead, it’s about the machine that built it.

ASML Holding N.V. (NASDAQ:ASML) CEO Christophe Fouquet revealed Wednesday that Intel is already producing commercial chips using the company’s most advanced lithography system, calling the achievement “a very important milestone.”

The comment marks a turning point for a technology that, until recently, was viewed as the future of semiconductor manufacturing rather than its present.

From Prototype To Production

“Some of the product you buy today from Intel have been created with a High-NA machine,” Fouquet told investors during ASML’s earnings call.

That distinction matters.

For years, ASML’s next-generation High-NA EUV systems — estimated to cost roughly $400 million each — have symbolized the next era of chipmaking. Investors have watched customers line up to buy them, but commercial production has remained the bigger question.

ASML’s latest update suggests Intel has already answered it.

Why Investors Should Care

Intel has spent much of the past decade trying to reclaim its manufacturing edge after losing process leadership to Taiwan Semiconductor Manufacturing Company Ltd. (NYSE:TSM).

Its turnaround strategy has relied as much on factories as products, with billions of dollars flowing into advanced manufacturing technology. If Intel can successfully integrate ASML’s newest machines into high-volume production, it could strengthen one of the company’s biggest competitive advantages: its ability to design and manufacture leading-edge chips under one roof.

The announcement also reinforces ASML’s broader message that AI-driven chip demand continues to justify heavy investment in next-generation manufacturing equipment.

The Next Milestone To Watch

One production milestone won’t decide the semiconductor race.

Intel still faces fierce competition from TSMC and Samsung Electronics Co., Ltd. (OTC:SSNLF), both of which continue investing aggressively in advanced manufacturing. The real test will be whether Intel can translate its manufacturing progress into higher-volume production, competitive products and foundry wins.

Still, ASML’s comments suggest one thing is no longer theoretical. Its most advanced chipmaking technology has moved beyond the lab — and chips built with it are already reaching customers. For investors watching Intel’s turnaround, that’s a milestone worth paying attention to.
