But that does not mean every new iPhone or Mac will use a U.S.-made processor. TSMC’s Arizona fabs are adding newer process technology in stages, while Taiwan remains ahead on the leading edge.
What TSMC said about building U.S. fabs faster
The March 2025 report said TSMC expected to build future U.S. fabs more quickly than its first Arizona facility, whose development took about five years. The reported target was roughly two years for subsequent fabs. That was investor guidance reported secondhand, not a guarantee that each facility would be ready for high-volume production on that schedule. The original report also relayed expectations for a U.S. 3nm fab around 2028 and 2nm production before 2030.
Construction is only one milestone. A fab must also install and qualify equipment, improve yields, and reach the volume and consistency customers need. A faster build therefore means additional capacity and process technology may become available sooner; it does not mean all Apple chips move to the United States at once.
What Arizona is making, and what comes next
TSMC’s first Arizona fab entered high-volume production of 4nm-class chips in the fourth quarter of 2024. TSMC’s 2025 annual report says its second Arizona fab is being accelerated, with 3nm high-volume manufacturing targeted for the second half of 2027. Construction on the third fab began in 2025; TSMC’s Arizona plan associates it with 2nm and A16 technologies, with production targeted toward the end of the decade. TSMC’s annual report and its Arizona project page describe the schedule.

It says initial construction activity for a fourth fab and the first advanced-packaging fab began in early 2026, and lists additional facilities for 2nm and below technologies announced in July 2026. The page gives $265 billion as the current Arizona program investment figure; that is the expanded program, not the original commitment for a single fab.
Apple’s February 2026 update says it expects to buy well over 100 million advanced chips made by TSMC in Arizona during 2026. In August 2025, Apple said the site was producing tens of millions of chips for it. Those figures describe Apple’s purchases or production across chip types; they are not a count of Apple-designed A-series or M-series processors alone. Apple’s 2026 update and its 2025 manufacturing announcement provide the figures.

Which Apple chips are made in Arizona?
Apple confirms that TSMC Arizona makes chips for its products, but it has not published a complete product-by-product allocation. The original 2025 coverage associated the first fab with older-node Apple chips, including the A16, but that specific allocation comes from supply-chain reporting rather than a comprehensive public list from Apple or TSMC. It is safer to say that Arizona is producing some Apple chips, not that a named current iPhone or Mac necessarily contains one.
“Older” here is relative to the newest process generations, not a judgment that a chip is obsolete. In general, a smaller process-node number indicates a newer generation, but node names are not literal transistor measurements and are not directly comparable across manufacturers. A 4nm-class chip can be advanced technology while still being behind a newer 3nm or 2nm design.
That timing helps explain why a fab can produce useful Apple chips without making the latest processor in every product. The chip mix depends on the products, qualified processes, capacity and Apple’s allocations—details the companies do not disclose comprehensively.
Why Taiwan remains ahead on the leading edge
TSMC says its 2nm technology entered high-volume manufacturing in Taiwan in the fourth quarter of 2025, with a fast ramp expected in 2026. Arizona’s second fab is targeting 3nm production in the second half of 2027, and its third fab is associated with 2nm and A16 technologies later in the decade. Arizona is closing the gap, but its published schedule remains behind Taiwan’s leading-edge ramp.
Rank #4
This is expansion, not a transfer of all TSMC’s newest technology from Taiwan to Arizona. The location of a fab also does not tell you where the process was invented or where a chip was designed. Apple designs its own silicon; TSMC fabricates wafers using its process technology. Those are distinct roles.
What “made in the U.S.” covers—and what it does not
A finished chip depends on more than wafer fabrication. The U.S. effort involves multiple suppliers and stages, and a chip fabricated in Arizona may still rely on facilities elsewhere for packaging or other steps until local capacity is operating.

Best Value
- Silicon wafers: GlobalWafers America is producing 300mm wafers in Sherman, Texas.
- Wafer fabrication: TSMC Arizona processes wafers into dies. Other U.S. suppliers also contribute chips and components.
- Packaging and testing: Amkor is developing an advanced packaging and test facility in Peoria, Arizona. Apple named itself the project’s first and largest customer in 2023; in February 2026 it said Amkor had broken ground on the planned $7 billion facility. Apple’s 2023 announcement and 2026 update describe the project.
- Design and process research: Apple designs its chips, while TSMC’s most advanced process research remains centered in Taiwan.
Apple describes its program as an effort to build an end-to-end U.S. silicon supply chain. That is a direction, not proof that every material, tool, design activity and manufacturing stage is already domestic. Apple has also said roughly two-thirds of components made in the United States are exported outside the country, so U.S.-made components can support products sold globally rather than only devices sold in America.

Additional U.S. capacity gives Apple another geographic source for some chips and components. That can help diversify a supply chain exposed to regional disruption, shipping problems or geopolitical risk. The value is resilience and added capacity over time, not a promise that every shortage will be avoided or that products will become cheaper.
The program also builds domestic supplier, workforce and packaging capacity. But scaling advanced manufacturing requires coordinated equipment, skilled workers, reliable water and power, qualified processes and strong yields. A fab can be open and producing while still ramping toward the volume and process generation available elsewhere.
For buyers, there is no reason to expect a performance change simply because a chip was fabricated in Arizona rather than Taiwan. Apple validates the chips it uses; the manufacturing location alone does not establish a different user experience. Nor does an Apple product assembled in the United States necessarily contain a U.S.-fabricated processor.

In the 2025 report, former Intel CEO Pat Gelsinger argued that factories alone would not make the United States a semiconductor leader if process research and development remained elsewhere. That is his view, not a settled measure of national leadership. It does highlight three separate questions: where chips are manufactured, where the manufacturing technology is developed, and where the product and chip are designed. Building Arizona manufacturing capacity addresses the first directly, but does not by itself settle the other two. The 2025 report recounts his criticism.
