Intel says its newest Arizona fab has processed its first wafer lot and is preparing to ramp production of its most advanced 18A process. The company reported that Fab 52 “run the lot” milestone was achieved this spring, that 18A volume will begin in Oregon, and that Arizona manufacturing will ramp later in 2025. The update came at Intel’s Direct Connect event and in subsequent disclosures.
The push adds a domestic node that Intel positions as a return to leadership with RibbonFET transistors and PowerVia backside power. These are highlighted in the company’s annual report and milestones posts as the cornerstone technologies for 18A.
“Intel is committed to building a world-class foundry that serves the growing need for leading-edge process technology,” the company said at its April 29 showcase.
How CHIPS incentives and a $32 billion build support Arizona
Washington has tied federal money to clear milestones. The Department of Commerce approved up to $7.865 billion in CHIPS incentives for Intel on November 26, 2024, stating funds will be disbursed as projects hit construction, technology, production, and commercial thresholds. The agency’s notice cites multiple Intel expansions across Arizona, New Mexico, Ohio, and Oregon.
At the local level, Intel describes more than $32 billion invested to build Fab 52 and Fab 62 and to modernize its Ocotillo campus in Chandler. The company has detailed construction milestones and tool installations tied to the ramp.
Timeline from April 2025 to early 2026
Intel’s investor materials state that Intel 18A is expected to ramp in the second half of 2025 to support the first Panther Lake client processor by year-end, with additional SKUs in the first half of 2026. The Form 10-K also notes that Panther Lake is the first 18A client family and reiterates 18A’s technical features.
The company has emphasized that 18A development and early volume begin in Oregon, which historically houses Intel’s process R&D and early manufacturing, while Arizona adds capacity as the ramp proceeds. Independent coverage of Intel’s Direct Connect event has echoed those points, including the run-the-lot step at Fab 52.
What is and is not confirmed today
Some trade press and local reports suggest 18A production activity in Arizona during the fall. For example, a TrendForce brief aggregated third-party reports about limited 18A shipments and characterized Arizona as entering 2 nm-class mass production.
These assertions are not reflected in a dated Intel filing or U.S. government notice, and Intel’s own April update described Arizona as “ramping later this year,” not already in volume. As of today, a primary record confirming a production start in Arizona on October 9, 2025 is unavailable, so that specific claim remains Unverified.
What comes next
Intel says it will ramp 18A in 2025, ship the first Panther Lake SKU by year-end, and follow with more SKUs in the first half of 2026. Investors get the next checkpoint when Intel reports third-quarter 2025 results on October 23, 2025. Those materials typically include brief updates on manufacturing milestones.
