Event: 2026 International Circuit & Systems Symposium, Shanghai
🔬 English Summary
At the 2026 International Circuit & Systems Symposium in Shanghai, He Tingbo — Huawei director and President of the Semiconductor Business Division — officially unveiled the "Tau (τ) Law", a new guiding principle for semiconductor industry development. This is the first time China has proposed a framework to guide global semiconductor industry evolution.
Key Announcements
| Aspect | Detail |
|---|---|
| New Principle | "Tau (τ) Law" — replaces "geometric scaling" with "temporal micro-scaling" |
| Core concept | Reduce time constants (τ) systematically through "logic folding" and other innovations |
| Goal | Compress signal propagation delay and continuously increase transistor density |
| Track record | Huawei has designed and mass-produced 381 chips over the past 6 years using this approach |
| Next milestone | New Kirin mobile chip coming Fall 2026, fully adopting logic folding technology |
| 2031 target | Transistor density equivalent to 1.4nm process node |
What Is the Tau (τ) Law?
The Tau Law proposes a fundamental shift from geometric scaling (shrinking transistor dimensions — the traditional Moore's Law path) to temporal scaling (reducing signal propagation time constants, denoted τ).
As geometric scaling slows due to physical limits and diminishing economic returns, the Tau Law offers an alternative path: through logic folding and other innovative techniques, compress signal delays and increase effective transistor density at the device, circuit, chip, and system levels.
Why It Matters
- Moore's Law hitting limits: Traditional geometric scaling is slowing; cost advantages are fading
- New paradigm: A multi-level co-optimization framework spanning devices → circuits → chips → systems
- Open collaboration: He Tingbo explicitly invited global scientists and industry partners to collaborate under the Tau Law framework
The Bigger Picture
He Tingbo's message: "The future belongs to open cooperation. Under the Tau Law, we look forward to working closely with global scientists, engineers, and industry partners to jointly drive the continued development of the semiconductor and electronics industry."
🔬 中文摘要
在2026国际电路与系统研讨会上，华为公司董事、半导体业务部总裁何庭波正式发表了"韬（τ）定律"。这是中国在全球半导体领域首次提出指导产业发展的新原则。
核心发布
| 方面 | 详情 |
|---|---|
| 新原则 | "韬（τ）定律"——以"时间缩微"替代"几何缩微" |
| 核心理念 | 系统性降低时间常数（τ），通过逻辑折叠等创新技术压缩信号传播时延 |
| 目标 | 持续提升晶体管密度 |
| 已有成果 | 过去六年华为已基于该理念设计并量产 381 款芯片 |
| 下一里程碑 | 今年秋季发布全新麒麟手机芯片，完整采用逻辑折叠技术 |
| 2031年目标 | 晶体管密度达到 1.4nm 制程同等水平 |
什么是"韬（τ）定律"？
韬定律提出了一个根本性的转变：从几何缩微（缩小晶体管尺寸——传统摩尔定律路径）转向时间缩微（降低信号传播时间常数 τ）。
随着几何缩微因物理极限和经济红利消退而放缓，韬定律提供了一条替代路径：通过逻辑折叠等创新技术，在器件、电路、芯片到系统层面实现多层级协同优化，压缩信号时延并提升等效晶体管密度。
为什么重要
- 摩尔定律遭遇瓶颈： 传统几何缩微放缓，成本优势消退
- 新范式： 贯穿器件→电路→芯片→系统的多层级协同优化框架
- 开放合作： 何庭波明确邀请全球科学家和产业伙伴在韬定律框架下合作
原文金句
何庭波表示："未来一定属于开放合作。在'韬定律'的路径下，我们期待与全球科学家、工程师和产业伙伴紧密合作，共同推动半导体与电子产业持续发展。"
