Huawei Proposes Tau Scaling Law as Replacement for Moore's Law at IEEE ISCAS 2026 (huawei.com)

• Huawei unveiled Tau Scaling Law at IEEE ISCAS 2026 in Shanghai.
• Law proposes time scaling instead of geometric scaling for semiconductors.
• LogicFolding architecture to be used in Kirin chips from Fall 2026.
• 381 chips designed under Tau Law over six years.
• Target of 14Å (1.4nm) equivalent transistor density by 2031.

"At the 2026 IEEE ISCAS, Huawei's He Tingbo presented the Tau (τ) Scaling Law, a new principle for semiconductor evolution based on time scaling rather than geometric scaling. Huawei claims this law enables continuous transistor density improvements through technologies like LogicFolding. The company states it has designed 381 chips under this law over six years, with Kirin chips in Fall 2026 being the first to adopt LogicFolding. By 2031, high-end chips are expected to achieve transistor density equivalent to 14Å (1.4nm) processes."
