Samsung’s foundry division just pulled off one of the most dramatic semiconductor turnarounds in recent memory. Its 2nm GAA yields have now climbed to 60%, more than tripling from just 20% in the second half of 2025 — and the chip industry is taking notice.
Samsung 2nm GAA: Progress at a Glance
| Metric | Details |
|---|---|
| Current Yield | ~60% |
| Yield in 2H 2025 | ~20% |
| Process | 2nm Gate-All-Around (GAA) |
| vs TSMC 2nm Yield | 60–70% (TSMC) |
| Samsung Foundry Market Share | 7.3% vs TSMC’s 70.2% |
| Key Customers Secured | Tesla (AI6), Canaan, MicroBT, Exynos 2600, Apple image sensors |
| Foundry Profitability Target | 2027 |
| Perf Gain Over 3nm GAA | +5% performance, +8% power efficiency, -5% area |
From Disaster to Comeback in Two Quarters
Six months ago, Samsung couldn’t crack 20% on this node — that was around the time people started calling the foundry business a lost cause. What changed? An unlikely catalyst: Bitcoin mining equipment companies Canaan and MicroBT commissioned 2nm production, giving Samsung’s engineers the sustained volume they needed to crack defect density problems on GAA transistors. More than tripling yield at the leading edge in two quarters isn’t routine — it’s fundamental materials science and metrology work done right.
Big Customers Are Already Signed Up
Samsung has secured a $16.5 billion contract to manufacture Tesla’s AI6 chips, orders for the Exynos 2600 smartphone AP, Apple image sensors, and mining ASICs from Canaan, with industry sources expecting Qualcomm to eventually join the lineup. The Exynos 2600 itself is already in mass production — delivering CPU performance up to 39% higher than the Exynos 2500 and 113% better generative AI performance, powered by a deca-core Arm architecture design. Samsung’s Taylor, Texas plant is set to begin operations in 2026, with production capacity expected to more than double by end of year.
TSMC still dominates — maintaining 2nm yields between 60 and 70% with Apple having booked over half its N2 capacity — but Samsung’s GAA head start is a real differentiator. TSMC is only now adopting GAA at 2nm, whereas Samsung has already accumulated hands-on GAA experience from its 3nm ramp, however troubled that ramp was.
