Has Huawei just rewritten the rules of chip design?

• Huawei’s Tau Scaling Law signals a fundamental break from Moore’s Law, with chips targeting 1.4nm-equivalent density by 2031
• The LogicFolding architecture, debuting in Kirin chips later this year, is already backed by six years of mass production across 381 chips

At the 2026 IEEE International Symposium on Circuits and Systems in Shanghai today, He Tingbo, chair of Huawei’s Scientist Committee and president of its semiconductor business, came with a proposition: that the Huawei Tau Scaling Law should replace Moore’s Law as the guiding principle for how the chip industry measures progress.

Her keynotetitled “New Semiconductor Path in Practice,” landed at ISCAS 2026 with the kind of weight that follows six years of quietly building something the industry didn’t know existed. By the time she finished, the global chip community had a new term to reckon with.

The Tau Scaling Law focuses on cutting the time it takes signals and data to move through chips and computing systems. Rather than chasing smaller transistors–the method that defined five decades of semiconductor advancement–Huawei’s framework focuses on time (τ) scaling to improve chip performance and transistor density. He’s peers have taken to calling it “Her’s Law.”

What makes the official announcement notable is the specificity of the architecture underneath it. Huawei describes a multi-level co-optimisation mechanism that works simultaneously across four layers: at the device level, by minimising resistance and parasitic capacitance in transistors and interconnects; at the circuit level, through LogicFolding, which breaks the physical boundaries of traditional circuit layouts to shorten critical-path wiring; at the chip level, through full-stack coordinated design of software, architecture and silicon for workload-driven efficiency; and at the system level, through a new interconnect protocol called UnifiedBus, which enables unified memory addressing for SuperPoDs and cuts communications latency.

That’s not a single clever trick. It’s a rearchitecting of how performance is extracted across the entire stack.

It’s a semantically elegant pivot. And strategically, it’s a lifeline.

What LogicFolding actually does

Huawei’s LogicFolding architecture breaks away from traditional physical circuit layout boundaries to shorten critical signal paths and reduce resistive and capacitive loads to improve performance. The result, Huawei says, is a sustained improvement in transistor density without requiring the lithographic precision that companies like TSMC and Samsung depend on.

Huawei claims its future high-end chips based on the Tau Scaling Law could achieve transistor density levels equivalent to 14-angstrom, or 1.4nm-class, process technologies by 2031. The company stopped short of claiming it would manufacture a true 1.4nm chip in the conventional foundry sense; the emphasis appears to be on density equivalence achieved through architectural and system-level innovation.

That’s an important distinction. Equivalence is not parity. But in the context of an industry being cut off from EUV equipment, equivalence is remarkable. China is widely seen as unlikely to reach leading-edge nodes through conventional manufacturing alone because Washington has restricted its access to advanced lithography tools and other key semiconductor technologies.

The Tau Scaling Law, if it delivers on what Huawei claims, offers a way around that wall, not by breaking through it, but by building a different door entirely.

Six years in the making

He was candid about the timeline. “I used to think it might take us 10 years, but six years we are here,” she said. Huawei has spent that time building a domestic stack, including electronic design automation tools and chip design methodologies, as China pushes to reduce reliance on foreign technologies.

Huawei had been using the Tau Scaling Law to design and mass produce 381 chips over the past six years, spanning smartphones, AI computing and beyond. The new Kirin chips, due in Fall 2026, will be the first ever to adopt the LogicFolding architecture, which will considerably enhance the chips’ performance.

He offered a preview of what’s coming before the year ends: “Before winter 2026, we will bring the surprise… a big leap ahead.”

The Ascend roadmap runs alongside

The timing of this announcement isn’t incidental. Huawei’s Ascend chip series has become increasingly central to powering Chinese AI models, including DeepSeek’s latest flagship model V4, released last month. Demand for domestic AI silicon is rising fast as enterprises seek Nvidia alternatives.

Huawei plans to launch its Ascend 950 series, including the 950PR and 950DT models, in 2026, with the Ascend 960 following in 2027 and the Ascend 970 in 2028, running parallel to AI chip releases from Nvidia and Advanced Micro Devices.

SMIC shares rose 7.6% on Monday after Huawei’s announcement, a market signal that investors read as meaningful progress, not just positioning.

What it means beyond China

He closed her keynote not with a competitive declaration but an invitation. “We believe that openness and collaboration are key to driving ongoing progress in the semiconductor industry. No single company can independently find all the answers along the path of semiconductor evolution,” she said, per Huawei’s official statement.

“With the τ Scaling Law, we look forward to working closely with scientists, engineers, and industry partners around the world.” That framing matters. This wasn’t announced as a weapon in a trade war. It was presented at an IEEE symposium, in the language of academic contribution. Whether the global semiconductor community engages with the Huawei Tau Scaling Law as a genuine scientific proposition, or dismisses it as statecraft dressed in physics, will say as much about the industry’s politics as its progress.

The question is no longer whether Huawei can innovate under pressure. The real question now is whether the rest of the world is paying close enough attention.
