Huawei Unveils Tau Scaling Law To Advance High-End Chips

Huawei Technologies expects to design high-end chips with transistor density equivalent to 1.4-nanometre processes by 2031, despite U.S. sanctions that have complicated China’s access to advanced semiconductor manufacturing tools.

The company revealed the projection on Monday while introducing what it calls the Tau Scaling Law. Huawei described the concept as a new principle for improving chip performance as the semiconductor industry faces growing limits in shrinking transistors through conventional scaling methods.

Huawei Introduces New Semiconductor Approach

He Tingbo, president of Huawei’s semiconductor business and director of its Scientist Committee, presented the new concept during a keynote speech titled “New Semiconductor Path in Practice” at the 2026 IEEE International Symposium on Circuits and Systems in Shanghai.

Huawei said the Tau Scaling Law focuses on reducing the time required for signals and data to move through chips and computing systems. As a result, the company believes the method could improve both performance and chip density even without full access to the world’s most advanced semiconductor equipment.

Although Huawei did not release independent performance benchmarks, the target drew attention because 1.4-nanometre technology is expected to remain close to the global cutting edge by the end of the decade.

U.S. Restrictions Continue To Shape China’s Chip Industry

Washington has imposed restrictions on China’s access to advanced lithography systems and other semiconductor technologies. Consequently, many analysts consider it difficult for China to match leading global chipmakers through traditional manufacturing approaches alone.

Huawei’s proposed strategy therefore represents an alternative path that relies less on further transistor miniaturisation. Instead, the company aims to improve chip efficiency by redesigning internal architecture and shortening data transmission paths.

The company said this approach could help offset limitations created by export controls and technology restrictions.

Kirin Chips To Use LogicFolding Architecture

Huawei also announced that its Kirin chips scheduled for release in autumn 2026 would become the first products to adopt a related architecture known as LogicFolding.

According to the company, LogicFolding shortens wiring distances inside chips and significantly improves performance. Huawei said the architecture supports the broader goals of the Tau Scaling Law by accelerating communication within semiconductor systems.

In addition, Huawei stated that it had already designed and mass-produced 381 chips based on the Tau Scaling Law during the past six years. These chips serve industries including smartphones and artificial intelligence computing.

The announcement highlights Huawei’s continuing efforts to develop advanced semiconductor technologies despite growing geopolitical and technological challenges.
