TSMC is stepping on the gas again. Even before 2nm chips have reached broad adoption, the world’s leading foundry is reportedly accelerating its 1.4nm manufacturing node, laying the groundwork to extend its process lead into the next decade.
According to local reports, TSMC has made a key breakthrough that enables it to pull forward its 1.4nm plans. The company is preparing four new factories dedicated to the node, with suppliers already being told to line up the required equipment. The roadmap suggests risk trial production could wrap up by the end of 2027, clearing the way for mass production in the second half of 2028.
Here’s how the rollout is shaping up:
– Four fabs are planned for the 1.4nm era.
– Phase one: two fabs target mass production in 2028.
– Phase two: the remaining two fabs are being positioned for an even more advanced 1nm process.
This accelerated push comes as rivals rethink their own roadmaps. Industry chatter indicates Intel may pause development of its A14 (1.4nm-class) process, while Samsung is reportedly shifting its 1.4nm ambitions to 2029 to prioritize stronger yields on 2nm.
All of this is happening while the broader market is only just trickling into 3nm. On the PC side, Intel’s Arrow Lake and Lunar Lake leverage TSMC’s 3nm-class technology, and Apple’s M4 uses TSMC’s N3E, a second-generation 3nm process. As usual, the next big node is expected to land in mobile first: the Exynos 2600 slated for the Galaxy S26 series is tipped to be among the first 2nm smartphone chips. Apple is said to keep the iPhone 17 line on 3nm, with the iPhone 18 and its A20 SoC likely moving to 2nm.
Why this matters:
– Performance-per-watt gains: 1.4nm promises denser logic and efficiency improvements that could benefit everything from AI accelerators and data centers to ultra-thin laptops and flagship phones.
– Supply chain signal: TSMC’s call to equipment partners suggests design ecosystems and customers will start aligning their roadmaps earlier than expected.
– Competitive positioning: If TSMC hits its 2028 mass-production window for 1.4nm and pivots quickly to 1nm, it could widen its lead at a time when competitors are recalibrating.
The takeaway is clear: while 3nm is only beginning to filter through consumer devices and 2nm is next in line for mobile, TSMC is already paving the path for 1.4nm—and setting the stage for the eventual jump to 1nm soon after.
