On May 25, at ISCAS 2026, He Tingbo, Board Director and President of Huawei’s Semiconductor Business Department, officially unveiled a new chip development paradigm — the “Tau (τ) Scaling Law.” For decades, the industry followed Moore’s Law and kept shrinking transistors. However, this approach has hit physical limits, accompanied by soaring R&D costs and diminishing performance gains. Huawei has adopted a new path: instead of fixating on miniaturizing components, it strives to accelerate signal transmission speed and reduce transmission loss inside chips, replacing traditional geometric scaling with time (τ) scaling. It is like building express lanes inside a chip to enable more efficient data flow — upgrading performance by boosting speed.
This represents an innovative technological paradigm in the semiconductor sector. “The future belongs to openness and collaboration. On the path of semiconductor evolution, no single company can independently find all the answers. With the τ Scaling Law, we look forward to working closely with global scientists, engineers, and industry partners to drive the sustainable development of the semiconductor and electronics industry,” said He Tingbo. The launch of the Tau Scaling Law marks a landmark technological exploration for China’s semiconductor industry.
