Called IDM 2.0, it combined roughly $20 billion in new U.S. fab investment, modular tile-based processors, selective use of outside foundries, a new external foundry business and an IBM research collaboration. The strategy aimed to preserve Intel’s integrated manufacturing strengths while reducing dependence on any single process node or factory.
What Intel announced on March 23, 2021
Intel presented IDM 2.0 as an evolution of its integrated-device-manufacturer model. Instead of making every component internally through one manufacturing path, Intel proposed using three sources together:

- Intel’s own worldwide factories and process technology;
- third-party foundries when they offered better cost, performance, timing or supply flexibility; and
- a new business, initially called Intel Foundry Services (IFS), to manufacture chips for outside customers.
The announcement also connected that manufacturing strategy to modular products such as Meteor Lake, advanced packaging, new Arizona capacity and joint semiconductor research with IBM. Intel’s original announcement is available at Intel’s March 23, 2021 release.

Why Intel needed a different manufacturing model
Intel’s traditional advantage came from designing processors and manufacturing them in its own fabs. That integration could enable close optimization between a chip’s architecture and its process technology, but it also made manufacturing delays strategically painful. If an internal node slipped, products depending on that node could slip too.

IDM 2.0 was Intel’s answer to that concentration of risk. The company did not abandon its fabs. It planned to add more capacity while also admitting that the best manufacturing source could vary by product, component and schedule. A processor could therefore combine Intel-made silicon with tiles from an outside foundry, while Intel’s factories also served external customers.
The roughly $20 billion Arizona investment
What the money was for
Intel said it would invest approximately $20 billion in two new leading-edge fabs at its existing Ocotillo campus in Chandler, Arizona. The money described a multiyear expansion, not a single-year expenditure, and the announcement did not assign both fabs to one specific product or process node.
The planned fabs were intended to supply Intel products and provide committed capacity for future Intel Foundry Services customers. That dual purpose explains why the project was central to IDM 2.0: it increased Intel’s own manufacturing footprint while creating potential capacity for a new customer business.

Jobs and timing were projections
Intel estimated that the project would create more than 3,000 permanent high-tech jobs, more than 3,000 construction jobs and approximately 15,000 additional long-term local jobs. Those figures were company forecasts, not independently verified employment results at the time of the announcement.
Intel later announced groundbreaking for the two fabs in September 2021, describing the expansion as part of more than $50 billion in total investment in Arizona. See the groundbreaking announcement.

Why the location mattered
Arizona offered an established semiconductor ecosystem, experienced workforce and existing Intel infrastructure. The project was therefore an expansion of a substantial manufacturing campus, not Intel’s first presence in the state. Intel said its Ocotillo Fab 42 was fully operational in 2020 and producing processors on its 10nm process.
Additional U.S. leading-edge capacity also had supply-chain and policy significance. It could reduce reliance on geographically concentrated production and give Intel a domestic base from which to offer foundry capacity. A new fab, however, does not automatically mean immediate high-volume production or instantly available capacity for every customer and process.
Meteor Lake and the meaning of “7nm tiles”
How the tile design worked
Intel used Meteor Lake to illustrate a move away from a single, monolithic die. A tile is a separately manufactured piece of silicon that is assembled into one processor package. The compute tile contains the principal CPU-compute functions; supporting tiles provide other functions and can be built on different processes.
Intel’s March 2021 material said Meteor Lake’s 7nm compute tile was expected to reach tape-in in the second quarter of 2021. Tape-in means the design was sufficiently complete to enter the manufacturing flow; it was not a claim that a finished retail processor had already shipped.
Why the terminology changed
The original announcement called the compute tile “7nm.” Intel later adopted its numerical process naming and identified the Meteor Lake compute tile as Intel 4. Later Intel material also said some supporting tiles would be manufactured by TSMC. Intel’s September 2023 announcement of high-volume Intel 4 production in Ireland linked that process to the Meteor Lake/Core Ultra generation.

Consequently, “Meteor Lake 7nm” is historically accurate for the wording used in 2021, while “Meteor Lake on Intel 4” reflects later product and process branding. Neither label should be treated as a literal transistor dimension or assumed to be directly equivalent to another company’s “7nm” label. Process-node names are technology-generation and marketing labels whose definitions differ among manufacturers.
Why modular tiles mattered
Separating a processor into tiles lets Intel choose manufacturing technology by function:
- Leading-edge silicon can be reserved for compute-heavy logic.
- Less performance-sensitive components can use a mature, lower-cost process.
- Selected tiles can come from an outside foundry.
- Reusable tiles can reduce dependence on one large monolithic die.
- Advanced packaging can combine dies made by different processes or suppliers.
This flexibility also adds engineering and operational costs. Intel had to validate multiple dies, manage interconnect, power and thermal behavior, coordinate suppliers and achieve reliable package-level yields. Packaging, assembly and supply-chain execution became as important as transistor scaling.
Why Intel would outsource some manufacturing while building fabs
Under IDM 2.0, manufacturing was no longer an all-or-nothing choice. Intel said it would use external foundries when doing so improved cost, time to market, performance or supply resilience. The decision could be made for an entire product or for one tile inside a product.
Intel’s later architecture update specifically described Meteor Lake as using an Intel 4 compute tile alongside supporting tiles made at TSMC, and discussed outside-foundry nodes for some graphics products. That was not an abandonment of Intel manufacturing. It was a portfolio approach: use Intel capacity where it is strongest and external capacity where it provides a better product or schedule outcome.

| Manufacturing option | Strategic benefit | Trade-off |
|---|---|---|
| Intel-owned fabs | Control over process, supply and design-manufacturing integration | High fixed capital cost and exposure to internal execution |
| External foundries | Access to alternative nodes, capacity and schedules | Supplier dependence, capacity-allocation and coordination risks |
| Mixed tile production | Best-fit process for each component | More packaging, validation and supply-chain complexity |
What Intel Foundry Services was supposed to be
IFS was intended to be a complete external foundry business, not simply a way to rent out idle Intel factory space. Intel proposed offering customers:
- leading-edge process technologies;
- advanced packaging and assembly options;
- committed U.S. and European capacity;
- Intel intellectual property;
- support for x86, Arm and RISC-V ecosystems; and
- design enablement and ecosystem partnerships.
A credible foundry must provide process design kits, design rules, electronic-design-automation compatibility, intellectual-property libraries, packaging choices, customer engineering support, predictable yields and confidentiality. It must also persuade customers that their designs will be protected even though Intel sells competing products. Those ecosystem and trust requirements are as important as the existence of a fab.
Intel later broadened the branding to Intel Foundry, describing it in 2024 as a “systems foundry” for the AI era. The later name reflects a wider offering around process, packaging, software and system-level services; it should not be read back into the exact 2021 IFS announcement. See Intel’s Intel Foundry roadmap and updates.

Intel and IBM announced a research collaboration focused on next-generation logic technologies, semiconductor packaging, manufacturing innovation, U.S. semiconductor competitiveness and related government initiatives. IBM brought deep semiconductor research expertise and an established research ecosystem; Intel brought process-development, packaging, manufacturing and commercialization capabilities.
The announcement did not disclose a customer-fab contract, a merger, a commitment to manufacture IBM’s commercial processors or a transfer of an entire IBM production process to Intel. It was a research and development relationship, as described in the IBM announcement.

How the four parts fit together
| Element | Purpose within IDM 2.0 |
|---|---|
| Two Arizona fabs | Add U.S. manufacturing capacity for Intel products and potential foundry customers. |
| Meteor Lake tiles | Demonstrate modular architecture and the ability to mix process technologies. |
| External foundry use | Improve flexibility when another supplier offers a better node, cost, schedule or supply position. |
| Intel Foundry Services | Turn Intel’s process, packaging and design ecosystem into a business serving outside chip designers. |
| IBM collaboration | Strengthen upstream research in logic and packaging rather than announce a production contract. |
The common idea was control without dependence on a single path. Intel wanted to remain a chip designer and manufacturer, but also to choose among internal fabs, external suppliers and modular packaging according to each product’s needs.
Announcement, forecast and later evidence
These dates help separate what Intel promised from what it later reported:
- March 23, 2021: Intel announced IDM 2.0, the approximately $20 billion Arizona plan, IFS, Meteor Lake’s then-described 7nm compute tile and the IBM collaboration. See the SEC exhibit of the announcement.
- Second quarter of 2021: Intel expected the Meteor Lake 7nm compute tile to reach tape-in. This was a planned design milestone, not a shipment claim.
- September 2021: Intel announced groundbreaking for the two new Arizona fabs.
- September 2023: Intel announced high-volume Intel 4 manufacturing in Ireland, connecting the process to the Meteor Lake/Core Ultra generation. See the Intel Ireland announcement.
- February 2024: Intel presented the broader Intel Foundry identity and systems-foundry positioning.
Later milestones provide evidence about execution, but they do not turn every 2021 forecast into a guaranteed outcome. Capacity, customer commitments, yields, construction schedules and commercial economics remain separate questions.
What IDM 2.0 was really betting on
Intel was attempting to be four things at once: a leading processor designer, a high-volume integrated manufacturer, a selective user of outside foundries and a trusted supplier to companies that could compete with Intel. The difficult part was not announcing any one of those roles; it was making them work together.
Success required competitive process technology, reliable fabs, a mature packaging stack, software and EDA support, customer confidentiality and enough external demand to keep foundry capacity economically useful. A fab could be completed without immediately delivering leading-edge commercial volume, and “capacity” did not guarantee availability for every customer or node.
The defining idea of IDM 2.0 was therefore larger than the Arizona construction project. Intel wanted to control more of the semiconductor stack while becoming less dependent on any single factory, process node or manufacturing model.
