Can Any Foundry Replace TSMC? Alternatives Depend on the Chip

No single foundry is established as a universal, drop-in replacement for Taiwan Semiconductor Manufacturing Company (TSMC). Samsung Foundry offers advanced processes, packaging and design services, so it may be an option for some projects. Whether it can replace TSMC for a particular chip depends on process fit, redesign and qualification work, capacity, timing and packaging—not simply on whether another company makes semiconductors.

What does “replace TSMC” mean?

It can mean two different things: finding another manufacturer for a specific chip, or finding one company that can take over TSMC’s broad role across many customers and products. The first may be possible in some cases. The available evidence does not establish the second.

TSMC operates as a pure-play foundry: it manufactures customer designs and says it does not design, manufacture or market semiconductor products under its own name. That business model is part of what customers are choosing when they contract with it. In its 2025 annual report, Chairman and Chief Executive Officer C.C. Wei wrote, “Our success is predicated on our steadfast adherence to the pure-play foundry business model.” TSMC 2025 annual report.

Why TSMC is difficult to replace at scale

TSMC reported 12,682 products, 305 distinct technologies and 534 customers in 2025, alongside annual manufacturing capacity exceeding 17 million 12-inch-equivalent wafers. Those company-reported figures indicate a broad operation serving many different needs; they do not show that every individual chip lacks another manufacturing option. TSMC 2025 annual report.

Its technology mix also illustrates the scale of its advanced-process business. TSMC reported that technologies it defines as advanced—7-nanometer and more advanced—accounted for 74% of wafer revenue in 2025, with 3-nanometer technologies representing 24% of total wafer revenue. These are TSMC’s reported figures, not independent market estimates. TSMC 2025 annual report.

Can Samsung or Intel replace TSMC?

Samsung Foundry

Samsung is a documented alternative for some foundry requirements. Its published overview lists 3-nanometer gate-all-around (GAA) and 4- and 5-nanometer FinFET processes, specialty technologies, integrated 2.5D and 3D packaging, and design services. That establishes an offering to evaluate; it does not establish equivalent capacity, yield, performance or compatibility with a particular TSMC design. Samsung Foundry overview.

Intel and other foundries

The available sources do not provide a common, independent comparison of Intel or other foundries against TSMC and Samsung on yield, available capacity, delivery performance, design portability or customer qualification. It would therefore be misleading to claim that a named competitor can—or cannot—take over production of a particular chip without evidence about that design and manufacturing flow.

TSMC’s roadmap and geographic expansion

TSMC said its 2-nanometer technology entered high-volume manufacturing in the fourth quarter of 2025. The company’s 2025 annual report scheduled N2P and A16 production for the second half of 2026 and A14 volume production for 2028. These are company roadmap statements, not guarantees; production schedules can change. TSMC 2025 annual report.

The company is also expanding production beyond Taiwan, including in Arizona and Japan, with specialty capacity planned in Germany, while saying it will continue investing in Taiwan. This broadens where TSMC manufactures, but it does not create an independent supplier that replaces TSMC. TSMC 2025 annual report.

How to assess a replacement for a specific chip

A foundry is a credible alternative only if it can meet the requirements of the actual design and production program. A company’s published process list is a starting point, not proof that a design can move without changes.

1. Check process fit. Determine whether the alternative’s process can meet the chip’s power, performance, area and reliability targets.
2. Estimate design portability. Establish what changes to the design, intellectual property, electronic design automation (EDA) flow and validation would be required. The sources reviewed do not quantify portability costs or timelines.
3. Confirm capacity and timing. Verify that suitable manufacturing capacity is available when production is needed. The cited sources do not provide a comparable independent snapshot of capacity across foundries.
4. Check packaging and integration. Confirm the provider can deliver the required package, interconnect and multi-die integration. TSMC describes an advanced-packaging and chip-stacking portfolio, while Samsung lists integrated 2.5D and 3D packaging; those descriptions alone do not establish that a particular package is interchangeable. TSMC 2025 annual report; Samsung Foundry overview.
5. Require customer qualification. Confirm that the exact design and production flow have completed the customer’s qualification process before treating a second source as ready.

Verdict: alternatives exist, but the answer is chip-specific

“There are no replacements for Taiwan Semiconductor” is too absolute if it means no other foundry can do any comparable work: Samsung’s published portfolio shows that alternatives exist for some requirements. But the evidence does not demonstrate that any one competitor can universally replace TSMC across its customers, products, process needs, capacity and packaging. For a buyer, the useful question is not whether another company can replace TSMC in general, but whether it can manufacture this design, to specification, on the required schedule.
