Intel on Wednesday announced that it had started installing production tools at its Fab 62 in Arizona, and the fab is on track for mass production by late 2028. The company also reported progress on its Ohio One manufacturing complex and confirmed that it has integrated High-NA EUV lithography into high-volume manufacturing (HVM). Meanwhile, Intel continues to invest in its leading-edge process technology R&D, advanced packaging, and photomask production capabilities in the U.S., which puts the company ahead of the competition."There is an important difference between technologies made in America and technologies that are truly American-made," wrote Naga Chandrasekaran, executive vice president and chief technology and operations officer, Intel Foundry. "The difference lies in the research and development process that transforms ideas into manufacturable technologies."Fab 62 to begin operations in 2028Intel completed construction of its Fab 62 shell some time ago; now it is time for the company to begin installing production tools, which is what it is doing now. Intel expects the new facility to become operational before the end of 2028, although it has not disclosed when it intends to begin high-volume production or which nodes it will produce.(Image credit: Intel)Intel has not officially assigned Intel 14A to Fab 62, although the facility has been discussed as a potential manufacturing site for the node. Meanwhile, there is an important distinction between Intel's original plans for Fab 62 and its current commitments. When Intel announced Fab 52 and Fab 62 in Arizona, it said the two facilities would manufacture its most advanced process technologies, including Intel 20A (2nm-class) and 18A (1.8nm-class). Intel subsequently designated Fab 52 for Intel 18A manufacturing. Yet, Fab 62 remains unassigned. Given Intel's manufacturing process roadmap disclosed earlier this year, Fab 62 will be able to make chips on 18A, 18A-P, and 14A nodes. Intel currently manufactures Intel 18A chips at the neighboring Fab 52, whereas Fab 62 could potentially accommodate either additional Intel 18A capacity or the company’s next-generation Intel 14A process technology. However, Intel has yet to confirm its plans for the facility.The facility will become Intel's Fab 62, the sixth high-volume semiconductor manufacturing fab at its Ocotillo campus, which has served as one of the company’s primary production sites for decades. Intel has also not revealed Fab 62's planned wafer processing capacity, or the amount of capital expenditures required to complete the facility. Nevertheless, the installation of production equipment indicates that the project has progressed beyond construction of the building itself. The new fab will expand Intel’s manufacturing footprint in Arizona, where the company already produces leading-edge processors and operates advanced packaging, assembly, and testing facilities.Intel confirms High-NA EUV insertion into mass productionAnother noteworthy disclosure concerns Intel's deployment of High-NA EUV lithography. Intel was the first chipmaker to install a commercial High-NA EUV scanner at its D1X fab near Hillsboro, Oregon, and subsequently integrated the tool into high-volume manufacturing to produce its Panther Lake and other chips. The Gordon Moore Park at Ronler Acres in Oregon is where Intel develops its most advanced logic process technologies and initiates volume production of the latest processors. Usage of High-NA EUV to produce select tiles for Panther Lake CPUs at D1X is a natural fit for the development fab, as it helps Intel to better understand how these lithography systems work. Meanwhile, it seems (though Intel has not explicitly confirmed) that, for now, High-NA EUV scanners are used to produce the same circuits as Low-NA EUV machines, so the use of next-generation lithography systems does not necessarily provide significant advantages over existing litho scanners. Ohio One reaches another construction milestoneIntel has also made progress with its 'Ohio One' manufacturing complex in New Albany, Ohio. Construction workers recently installed the first major structural truss at the site's first semiconductor fab, which represents a milestone in the development of the company's manufacturing operations in the state. The project is clearly an important part of Intel's long-term strategy to expand domestic production of chips using leading-edge process technologies for years to come. (Image credit: Intel)Unfortunately, Intel did not provide an updated construction schedule for Ohio One or disclose when the first fab is expected to begin operations. Intel also did not reveal which process technology the facility will eventually use or the estimated manufacturing capacity it will provide. Therefore, while construction continues, which is good news, the announcement does not clarify when exactly Ohio One will contribute to Intel's output.Other investments across the U.S.In addition to leading-edge manufacturing capacity in the U.S., Intel continues to invest in advanced packaging technologies. Oregon serves as the company's main research and development center for advanced logic and 3D interconnect technologies, while Arizona hosts advanced packaging R&D, assembly, and testing operations. Intel uses its site in New Mexico to produce its complex multi-chiplet processors relying on advanced packaging methods — starting with modest EMIB and all the way to next-generation EMIB-T and Foveros technologies.(Image credit: Intel)Also, Intel recently broke ground on a new photomask manufacturing facility in Santa Clara, California. Again, the company has not disclosed its planned capacity or operational schedule. Meanwhile, the new facility will be an important part of Intel's supply chain in the U.S. as the company will be the only chipmaker in America to develop and produce chips using leading-edge nodes completely in the U.S. (both Samsung and TSMC currently lack leading-edge process R&D in America, they do not run their own photomask shops in the U.S., Samsung has abandoned its plan to build an advanced packaging facility in Texas). Of course, Intel critically depends on tools from Europe and materials from Japan, but even as its major rivals invest hundreds of billion in their U.S. production capacity, Intel remains ahead. To highlight its American supply chain, Intel disclosed that its U.S. operations involve more than 4,500 suppliers across 49 states as its annual domestic expenditures exceeds $29 billion. The company stressed that domestic semiconductor leadership requires not only wafer fabrication capacity but also research, process development, advanced packaging, and a comprehensive supply chain.
