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.

The United States and Iran reached an understanding on the issue of Iran's frozen financial assets on Monday through Qatari mediation, according to a source in Qatar familiar with the ongoing talks between the U.S. and the Iranian senior delegation in Doha.
The two sides are "very likely" to announce an agreement on Tuesday, as the issue of frozen financial assets is crucial to Iran, said the source.
The high-level Iranian delegation, which includes Iranian Parliament Speaker Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi, arrived in Doha on Monday for talks with Qatari officials on a possible peace agreement with the United States, according to Iran's semi-official Mehr News Agency.
The talks aim to advance diplomatic efforts mediated by Pakistan in recent weeks to end the "war of aggression imposed" by the United States and Israel against Iran, Mehr reported.
An official with the Qatari Foreign Ministry said that the talks focus on issues such as the Strait of Hormuz, Iran's highly enriched uranium stockpile, and frozen Iranian funds overseas. The Governor of the Central Bank of Iran Abdolnaser Hemmati was present in the delegation and responsible for discussing financial matters that might be involved in a final agreement.
Iran and the United States reached a ceasefire on April 8 after 40 days of fighting. Following the truce, they held one round of peace talks in Pakistan's Islamabad on April 11 and 12, which failed to yield an agreement.
