Huawei To Close Gap With TSMC From Breakthrough Chip Making

Catenaa, Monday, May 25, 2026- Huawei Technologies said it has developed a new pathway to manufacture chips to narrow the gap with industry leader TSMC.

There is about a five-year gap between what TSMC is capable of and what Huawei, together with its manufacturing partner Semiconductor Manufacturing International, can produce. 

Huawei will start making 1.4-nanometer chips by 2031 with its own “LogicFolding” technology, Huawei’s semiconductor Chief, He Tingbo, said in a rare public appearance at a chip conference on Monday, while TSMC has said it will begin mass production of the same product in 2028.

The executive said that her team has found a way for “sustainable evolution.” She told reporters after her speech on Monday that Huawei can advance its chipmaking prowess significantly without the use of Dutch supplier ASML Holding NV’s extreme ultraviolet lithography machines, widely considered essential for production of cutting-edge semiconductors that China doesn’t have access to.

He added that the Kirin mobile chips to be launched this fall will be the first to adopt the LogicFolding architecture, which helps boost the performance of a chip by increasing the number of transistors it carries and optimizing data transmission speed.

“This year, we have prepared a surprise for the whole industry. Not saturation, not continuation, but a big leap ahead,” she said.

The Star 50 Index in Shanghai, which includes several major Chinese chip firms, rose to a record after He’s announcement on Monday. Shares of SMIC rose more than 18% while foundry peer Hua Hong Semiconductor Ltd. surged by the daily limit of 20%.

If Huawei can manage to make 1.4nm semiconductors in large quantities, it means it’s defying the industry consensus that ASML’s EUV lithography machines are necessary to mass-produce chips that are 5nm or more advanced. Such semiconductors are used to power the most sophisticated AI technologies.

Huawei’s He added that the LogicFolding architecture is based on Huawei’s own Tau Scaling Law, a principle the Chinese company is adopting to rival Moore’s Law, the guideline for the global chip industry for decades. 

Moore’s Law, named after Intel co-founder Gordon Moore, is an extrapolation that the number of transistors in a chip will roughly double about every two years, though many in the industry, including He say the cadence has been slowing down in recent years.

He said that Huawei’s scaling efforts based on Moore’s Law plateaued six years ago after US export controls hit. Her team then proposed a new “time scaling” method to replace the global industry’s gold standard. Huawei’s new principle appears to focus on boosting data transmission speed by transistors to compensate for a lack of state-of-the-art equipment to shrink those components significantly further.

“We saw time scaling can deliver strong benefits across devices, circuits, chips and systems,” He said, adding that Huawei has designed and made 381 chips over the past six years based on the Tau Scaling Law.

Huawei, in a separate statement, said that the company is dubbing its new principle “Her’s Law,” in a nod to its chip chief.

The Shenzhen firm has previously filed for patents that show it is trying so-called self-aligned quadruple patterning, or SAQP, that may allow it to produce advanced chips without ASML’s EUV machines. 

Quadruple patterning is a technique for etching lines on silicon wafers multiple times to increase transistor density, and therefore performance.

While Huawei has continued to improve its technologies over the past few years, it is unclear whether it will indeed be able to reach the cutting edge of chipmaking by experimenting with a non-mainstream path.

Huawei has been at the vanguard of Beijing’s semiconductor self-sufficiency drive following a years-long US-led, multinational campaign to tighten exports of advanced chips and gear that have somewhat curbed China’s AI progress.

In September, Huawei announced a three-year roadmap to roll out a series of AI chips to fill the vacuum left by Nvidia, whose most advanced semiconductors are banned in China.
