Intel might axe the 18A process node for foundry customers, essentially leaving TSMC with no rival — Intel reportedly to focus on 14A (Updated)

Dropping external sales of 18A and 18A-P would require Intel to account for a substantial write-off reflecting the billions it spent developing the manufacturing technologies, according to individuals familiar with internal deliberations cited by Reuters. Depending on how you count development costs, the resulting charge could total hundreds of millions or even billions of dollars.

Both RibbonFET and PowerVia were initially developed for 20A, but that technology was cancelled for internal products last August in a bid to focus on 18A for both internal and external products.

Intel’s rationale behind the move may be rather simple. By limiting the number of potential customers for 18A, the company may potentially cut its operating costs. The majority of tools required for 20A, 18A, and 14A (except for High-NA EUV equipment) are already in place at its Fab D1D in Oregon, as well as at Fabs 52 and 62 in Arizona. However, once these tools are formally put into operation, the company will have to report their depreciation as a cost. Not putting them online potentially enables Intel to cut its costs amid uncertainties with orders from third-party clients.

In addition, by not offering 18A and 18A-P to external customers, Intel may save money on engineers dedicated to supporting the sampling, ramp, and mass production of third-party circuits at Intel fabs. Obviously, this is speculation on our side.

However, by ceasing to offer 18A and 18A-P to external clients, Intel will be unable to demonstrate advantages of its fabrication nodes to a broad range of customers with various designs, which would leave them with a single choice for next two or three years: go with TSMC and use N2, N2P, or even A16.

Although Samsung is set to formally start making chips on its SF2 (also known as SF3P) node later this year, that node is expected to be behind Intel 18A and TSMC’s N2 and A16 in terms of power, performance, and area.

Essentially, Intel would not be showing up to its fight against TSMC’s N2 and A16, which will certainly not help to gain the confidence of potential clients towards other Intel offerings, namely 14A, 3-T/3-E, Intel/UMC 12nm, and others.

Reuters’ sources familiar with the matter explained that Lip-Bu Tan had asked Intel’s specialists to prepare proposals for discussion with Intel’s board this fall. Options could include ceasing efforts to sign up new clients for 18A, though given the scale and complexity of the issue, the decision might not be finalized until the board meets again later this year.

Intel itself reportedly declined to discuss hypothetical scenarios but confirmed that the main customer for 18A has always been its own Products division, which plans to begin producing codenamed Panther Lake CPUs for laptops in 2025 using this technology. Eventually, 18A and 18A-P will be adopted by Clearwater Forest, Diamond Rapids, and Jaguar Shores products.

Intel’s push to attract large-scale external clients to its Intel Foundry fabs remains critical to its turnaround, as only with high volumes the company will be able to pay off for its process technologies that cost billions to develop.

However, in addition to Intel itself, only Amazon, Microsoft, and the U.S. Department of Defence have formally confirmed plans to use 18A. While Broadcom and Nvidia are also reportedly testing Intel’s latest process technology, they have yet to commit to using it for actual products.

Intel’s 18A has one key advantage over TSMC’s N2: it features backside power delivery, which is particularly useful for power-hungry processors aimed at AI and HPC applications. TSMC’s A16 with Super Power Rail (SPR) will only enter mass production in late 2026, so 18A will maintain the advantage of offering backside power delivery for Amazon, Microsoft, and potentially other customers for a while.

However, N2 is expected to offer higher transistor density, which is beneficial for the vast majority of chip designs. Furthermore, while Intel has been running Panther Lake silicon at its D1D fab for quarters (so, currently Intel is still in risk production using 18A), the company’s high-volume Fab 52 and Fab 62 started to run 18A test silicon this March, so they will start producing commercial chips only late in 2025, or rather in early 2025.

Intel’s external customers are, of course, interested in producing their designs at high-volume fabs in Arizona rather than at development fabs in Oregon.

Intel CEO Lip-Bu Tan is reportedly considering halting the promotion of the company’s 18A fabrication process to external clients and instead focusing on the next-generation 14A production node, aiming to attract large customers such as Apple and Nvidia.

The move could trigger massive write-offs, as Intel has spent billions developing 18A and 18A-P process technologies. Shifting focus to 14A could help cut costs and better prepare the node and operations for third-party clients, but the move risks undermining customer confidence in Intel’s foundry capabilities ahead of 14A’s planned production in 2027–2028.

While the 18A node remains critical for Intel’s own products, such as Panther Lake CPUs, limited demand from third parties — so far, only Amazon, Microsoft, and the U.S. Department of Defense have confirmed plans to use it — has raised concerns about its viability.

The potential decision — which will essentially withdraw Intel from the broad foundry market until 14A comes to market — will be reviewed by Intel’s board later this year. Even if Intel eventually chooses to remove 18A from its foundry offerings, aimed at a broad range of applications and clients, the company will still manufacture chips using 18A for its own products, which are already designed for the process. It also intends to fulfill limited orders it has already committed to, including supplying chips for the aforementioned clients.
