Intel-Foundry
A separate manufacturing business, not a brand name for Intel chips. Intel Foundry is Intel’s contract chip-manufacturing business, which builds wafers for outside customers in addition to Intel’s own processors. It grew out of the Intel Foundry Services unit Intel announced in 2021 as part of the IDM 2.0 strategy, and Intel began reporting it as a standalone business segment in 2024. Intel Foundry is the manufacturing arm; Intel Products is the separate unit that designs chips such as Core and Xeon, and is itself one of Intel Foundry’s customers.
18A is the process node built around RibbonFET and PowerVia. Intel’s 18A node combines RibbonFET, a gate-all-around transistor architecture, with PowerVia, a backside power-delivery scheme that moves power wiring to the back of the wafer and frees the front side for signal routing. Intel has described 18A as the first high-volume logic node to put both changes into production together. Panther Lake, Intel’s next client processor family, is the first Intel Products design built on 18A.
External customers have committed actual designs, not just interest. Microsoft has stated it is designing a chip to be built on Intel 18A. Amazon Web Services has a multi-generation agreement with Intel Foundry that includes a custom AI fabric chip. These are specific, named commitments rather than general expressions of support, and they are the test Intel Foundry has to pass: outside companies taping out real designs onto Intel’s process, the same way they would with any other foundry.
New fabs in Arizona and Ohio carry most of the committed capacity. Intel’s Fab 52 in Chandler, Arizona is building 18A capacity, and Intel has a second major site under construction near New Albany, Ohio. Both projects have drawn U.S. CHIPS and Science Act support alongside Intel’s own capital spending. Capacity under construction is not yet capacity in production; qualifying a new fab for external customers’ process requirements takes additional time after the building and tools are in place.
The foundry-versus-IDM distinction decides what the word actually promises. Intel has run fabs for its own chips for decades as an integrated device manufacturer; Intel Foundry is the attempt to additionally serve outside customers the way TSMC or Samsung Foundry do. That dual role is explicitly why a fab can sit in both the IDM and foundry categories at once, as the broader fab-versus-foundry distinction describes. Evaluating Intel Foundry means tracking external design wins, qualified yield, and node schedule, not treating the brand name as proof that the transition is finished.

Read Intel Foundry as a contract-manufacturing business whose credibility rests on external design wins and qualified yield at advertised nodes, not on the brand name alone.
