Huawei is signaling that U.S. chip restrictions have not ended its ambitions in advanced semiconductors. Instead, the company says it has found a design approach that could keep it competitive even as access to the most sophisticated chipmaking tools remains blocked.
That shift matters because the competition between the U.S. and China is no longer only about who controls production equipment. It is also about which company can design a smarter chip architecture when the best manufacturing machines are out of reach.
Designing around the blockade
At an event in Shanghai, Huawei outlined a new approach that it says could support the development of high-end processors without relying on the specialized chipmaking equipment used by Intel, Taiwan Semiconductor Manufacturing Co., and Samsung Electronics. The Wall Street Journal reported that the method is designed to work even without access to the most advanced lithography machines.
Huawei says the approach could reach transistor density comparable to chips built on a 1.4-nanometer process. Transistor density reflects how many tiny switches can be packed into a chip, and it is closely tied to computing performance and energy efficiency.
That benchmark draws attention because 1.4 nm is viewed as the next major milestone in the semiconductor industry. Several leading chipmakers are also planning to mass-produce chips at that level in the coming years using advanced lithography systems made by ASML in the Netherlands.
A different path to performance
Rather than relying only on shrinking components, Huawei says its strategy focuses on improving computing efficiency through a different architecture. The company stacks multiple circuit layers in a single chip and works to shorten the travel time for data between those layers.
Huawei calls the method the “Tau Scaling Law.” In the materials shown at the event, the company said the method has already been applied to 381 chip models over the past six years.
He Tingbo, president of Huawei’s semiconductor division, described the solution as “feasible and affordable.” The wording suggests Huawei wants to present the approach as both technically workable and economically realistic under sanctions pressure.
The company also said its next-generation Kirin smartphone processor, expected later this year, will be the first to use the “LogicFolding” architecture. That design aims to improve chip performance by shortening internal wiring paths and reducing communication delays between processor components.
Pressure from U.S. restrictions
Huawei said the same approach is also being used in AI chip development. However, the company has not provided independent benchmarks or outside performance evaluations to support those claims.
The announcement comes after years of tightening U.S. restrictions on Huawei and China’s semiconductor industry. Huawei was added to the U.S. trade blacklist in 2019, limiting its access to American technology.
Broader controls introduced in 2022 further restricted China’s access to advanced semiconductor equipment and high-end AI chips. Washington’s goal has been to slow China’s ability to build advanced AI systems and produce cutting-edge chips.
One part of that effort has been limiting Chinese companies’ access to Nvidia products and the manufacturing tools needed to make high-end chips. Those restrictions have pushed Chinese technology firms to look for alternative routes to develop advanced processors.
In that landscape, Huawei has become an important player in Beijing’s push for technological self-reliance and a domestic semiconductor ecosystem. The company’s latest message is clear: losing access to the best machines does not automatically end the race to build advanced chips.
