Huawei says new chip-design approach could reach 1.4-nanometer-equivalent density by 2031
The Facts
- Huawei said it expects to design high-end chips by 2031 with transistor density equivalent to a 1.4-nanometer process.
- The company presented a new semiconductor development principle called the Tau Scaling Law at the 2026 IEEE International Symposium on Circuits and Systems in Shanghai.
- He Tingbo, president of Huawei's semiconductor business, introduced the concept during the Shanghai event.
- Huawei says its approach includes a "LogicFolding" architecture that reorganizes circuits in vertically stacked active layers to shorten signal paths and improve transistor density and performance.
- Huawei said the new approach is meant to advance chip performance without relying on the most advanced chipmaking equipment that U.S. restrictions have blocked it from accessing.
- The 1.4-nanometer level is treated in the coverage as a leading-edge target that Intel, TSMC and Samsung are aiming to mass produce within the next few years.
- Reuters reported that Huawei did not provide independent performance data for its 2031 target, so whether the approach can deliver those results in large-scale manufacturing remains unresolved.
How left and right are reading this
- Both agree
- Huawei is claiming a way to keep pursuing leading-edge chip design despite blocked access to the most advanced equipment, but the central caveat is unchanged: without independent performance data, its 2031 target remains unproven in large-scale manufacturing.
- They split on
- Less a disagreement than a question of emphasis: the significance of a workaround for advancing under U.S. restrictions, versus the need to treat the 1.4-nanometer-equivalent claim cautiously until independent results and manufacturing viability are shown.

Context
What is Huawei's new approach?
Huawei calls it the Tau Scaling Law, a framework that shifts the focus from shrinking transistor geometry alone to reducing timing-related constraints across devices, circuits, chips and systems; the company says "LogicFolding" is one of the technologies used to do that SAPO,Reuters,Notícias ao Minuto.
Why does access to equipment matter here?
Huawei says its method could let it make more advanced chips without the specialized tools used by leading rivals, while Reuters and other reports note that U.S. sanctions have made it difficult for China to obtain the equipment needed for the most advanced chip production Hindustan Times,Yahoo News,Reuters.
What is still uncertain about Huawei's claim?
The company set a 2031 target for 1.4-nanometer-equivalent transistor density, but Reuters reported that Huawei did not provide independent performance data, and several reports frame large-scale production as the key unanswered test Yahoo News,Reuters,mint.
