The world’s most advanced chipmaker isn’t slowing down. TSMC is already laying the groundwork for 1-nanometer production while most of the industry is still catching up to 2nm.
First 2nm chips are just now entering the market. Major clients are locking in on TSMC’s N2 and N2P nodes. But TSMC’s roadmap doesn’t stop there, A14 (1.4nm) is already in the pipeline, and 1nm planning has begun. Twelve new fabs are currently under construction to support demand across multiple chip generations.
Don’t hold your breath for 1nm chips, though.
Mass production is still years away. The Longtan Phase III expansion tied to 1nm capacity won’t even enter land acquisition until 2029. Real output is realistically 2030 at the earliest, more likely 2031.
This isn’t a delay. It’s just how hard this gets at the edge of physics.
Samsung is pushing hard, but yield is the problem.
The South Korean rival is targeting 1nm production by 2029 and has been aggressive on 2nm, including in the US. The ambition is real. But yield stability remains its Achilles heel. When too many chips come out defective, big clients don’t wait around they stay with TSMC.
The gap between announcing a node and reliably producing it at scale is where chipmaking races are actually won or lost.
TSMC knows this better than anyone.
