China's tech giant Huawei on Monday announced the Tau Scaling Law, a breakthrough transcending from the geometric scaling logic that has long underpinned chip development and production cost.
The breakthrough was announced by He Tingbo, a Huawei board member and president of the company's semiconductor business department, at the 2026 Institute of Electrical and Electronics Engineers (IEEE) International Symposium on Circuits and Systems (ISCAS) held in Shanghai.
The Tau Scaling Law provides an alternative path for Moore's Law, which improves chip performance by shrinking transistor size and now faces technological bottlenecks, as device dimensions are getting closer to physical limits.
The Tau Scaling Law, however, proposes replacing geometric scaling with time scaling, enabling signals to run faster, shorter, and with less waiting time in the system, according to He.
"We saw time scaling can deliver strong benefits across devices, circuits, chips, and systems. The Kirin 2026 [mobile chip is] going to the market later this year. It marks our first-ever successful implementation of logic folding," said He. Driven by this news, the A-share chip sector surged on Monday, with the STAR Market 50 Index, which tracks the 50 largest stocks listed on China's sci-tech innovation board (commonly known as the STAR Market), hitting a new all-time high, and many stocks also hit their daily limit.
