Kuo: A20 chips in iPhone 18 models will be made using TSMC's 2nm process, as TSMC's trial production of 2nm chips reached yields well above the 60%-70% range
Apple supply chain analyst Ming-Chi Kuo today reiterated that the A20 chip in iPhone 18 models will be manufactured with TSMC's 2nm process.
Context & Ripple Effects
This report extends a multi-generation Apple-TSMC roadmap: coverage previously pointed to Apple using TSMC’s N3E process for A17 iPhone chips and M3 Mac chips in the planned 3nm transition. It now places the next reported iPhone-chip node transition at 2nm.
The reported yield progress matters because Apple has previously been described as receiving unusually favorable treatment on 3nm manufacturing defects, making ramp economics—not just process availability—central to its access to leading-edge production.
First-order effects
- Apple can plan the reported A20 around TSMC’s 2nm process for iPhone 18 models, while TSMC gains a prospective high-volume anchor customer for its new node.
- Trial yields above the cited range improve the practical case for moving 2nm from development toward volume production, though the report does not establish final production yields or timing.
Second-order effects
- A credible Apple 2nm commitment would increase pressure on other handset-chip designers to secure comparable leading-edge foundry capacity or compete on architectures and product positioning instead.
- TSMC’s ability to ramp 2nm economically could reinforce Apple’s supply advantage, particularly if the defect-cost arrangement reported for 3nm has set a precedent for how early-node risk is allocated.
Third-order effects
- If successive Apple chips continue to lead each node transition, advanced-node access may become an increasingly durable differentiator between companies with direct TSMC scale and those without it.
- The pattern also underscores semiconductor capacity lag: process leadership depends on converting promising trial yields into repeatable, high-volume output, which can constrain the pace at which the broader market adopts a new node.
The trend: This is another data point in the concentration of leading-edge mobile silicon around early access to TSMC’s newest manufacturing nodes.
