Samsung’s 2nm Access Opens Doors, But DigiTimes Says Most Customers Still Treat It as TSMC Backup

Samsung’s advanced foundry push is starting to earn it serious conversations with major chip customers, but a new report suggests those talks still come with a hard ceiling: access is improving, trust is not there yet. According to DigiTimes, companies exploring Samsung’s 2nm process are largely doing so as part of a backup or dual sourcing strategy rather than because they see the Korean giant as a true like for like alternative to TSMC. That distinction matters, because in the current AI and high performance chip market, simply having a 2nm class node on paper is not enough. Customers want stable, high volume output, and that is still where Samsung faces the toughest scrutiny.

The core issue remains yield. Recent reporting has painted a mixed picture for Samsung’s 2nm process, with DigiTimes saying yields have moved above 60%, while other industry reporting cited by TrendForce and BusinessKorea places effective readiness for stable mass production below where some major customers would want it. Qualcomm in particular has been linked to a higher internal threshold for large scale sourcing, with reporting indicating Samsung has not yet reached the kind of margin that would make dual sourcing straightforward for a flagship mobile platform.

That is why Samsung’s current position looks more tactical than transformational. It is attractive because it is one of the very few foundries with leading edge 2nm class ambition outside TSMC, and because many customers want leverage, cost flexibility, and supply chain insurance. But that does not automatically translate into bulk production wins. If yields remain inconsistent, the cost of a chip rises, delivery confidence weakens, and the appeal of using Samsung for major volume programs quickly narrows.

Tesla is the clearest example of this balancing act. DigiTimes recently reported that Tesla’s AI5 tape out supports a dual foundry structure involving both Samsung and TSMC, but the weight of that arrangement is not equal. Earlier DigiTimes reporting said Tesla had finalized AI5 design work and was pursuing production with both partners, while more recent coverage suggests Samsung is being kept for specific versions rather than as the main production backbone. In practical terms, Tesla appears willing to keep Samsung in the mix, but still leans on TSMC when it comes to confidence at scale.

That does not mean Samsung is out of the race. In fact, the opposite is true. The company’s biggest opportunity right now may be that even being the backup matters. In a market where TSMC’s most advanced capacity remains in extreme demand, being the only other foundry close enough to enter the conversation gives Samsung strategic relevance it would not otherwise have. The challenge is converting that relevance into durable, high volume trust. If Samsung can push 2nm yields materially higher and prove consistent execution, today’s backup role could become tomorrow’s real second source. If it cannot, then customers will keep the door open just enough to preserve optionality, not enough to shift their core business.

There is also a broader market reason this story matters. Advanced node manufacturing is becoming so expensive that customers increasingly need a credible alternative to TSMC, even if only to improve negotiating power and reduce concentration risk. Samsung’s presence at 2nm therefore has value beyond the wafers it ships. It gives hyperscalers, automotive firms, and mobile chip designers another path to explore. But that path only becomes truly viable when yield, timing, and production scale stop being question marks.

For now, the takeaway is straightforward: Samsung is getting meetings because it has advanced technology, but according to the latest supply chain reporting, it is still being judged as a contingency plan rather than a fully trusted replacement for TSMC. That is progress, but it is not yet parity.

Do you think Samsung can turn its 2nm access into real foundry momentum, or will it remain the industry’s backup plan for the next few years?
