Chinese chip stocks surge as Huawei unveils plan to match leading chips with 1.4-nanometer technology

Huawei Announces Breakthrough in Semiconductor Manufacturing

Chinese chip stocks experienced dramatic gains after Huawei Technologies disclosed plans to produce 1.4-nanometer chips by 2031 using its proprietary LogicFolding technology1

1

. Shares of Semiconductor Manufacturing International Corp. (SMIC), China's largest contract chipmaker, and Hua Hong Semiconductor Ltd. surged more than 16% as trading resumed in Hong Kong following a market holiday2

2

. The announcement came during an industry conference where Huawei executive He Tingbo, leading the company's chip research team, revealed the technological breakthrough that could help Chinese semiconductor firms match leading chips from global competitors1

LogicFolding Technology Offers Alternative Path Forward

Huawei's proposed manufacturing process represents a fundamental departure from traditional semiconductor industry approaches. The company's time-scaling method aims to improve transistor data transmission speeds rather than following Moore's Law's emphasis on shrinking transistor sizes1

1

. This major tech leap could potentially reduce the technology gap with industry leaders like Taiwan Semiconductor Manufacturing Co., Intel, and Samsung Electronics, all of whom are targeting mass production of 1.4-nanometer semiconductors within the next few years2

2

. Analysts suggest the innovation could reduce reliance on cutting-edge chipmaking equipment from ASML Holding NV, enabling Chinese firms to accelerate product launches while lowering production costs1

Market Response Signals Confidence in Chinese AI Ambitions

The rally extended across Hong Kong semi stocks, with GigaDevice Semiconductor Inc. climbing as much as 12% and Montage Technology Co. gaining around 6%1

1

. Hong Kong's Hang Seng Tech Index rose 1.8% on the news2

2

. Bernstein analysts described the advancement as potentially "another DeepSeek moment," referencing the Chinese startup that released an AI model performing on par with leading Western alternatives2

2

. The development holds strategic importance for Chinese AI and high-performance computing capabilities, particularly as U.S. export restrictions continue limiting access to advanced processors from Nvidia Corp1

Path to Technological Self-Reliance Faces Critical Tests

Huawei has become central to China's push for technological self-reliance amid years of tightening U.S.-led export restrictions targeting advanced semiconductor technologies1

1

. The approach offers an alternative roadmap for local chip companies to continue progressing despite trade curbs that have restricted China's access to foreign equipment since 20222

2

. If executed successfully, Bernstein noted the leap forward will generate massive upside for China's semiconductor sector, inspiring confidence in building a local ecosystem2

2

. However, market experts cautioned that LogicFolding technology remains unproven at scale, with a key test coming later this year when Huawei launches Kirin mobile chips expected to use the new process. Investors increasingly view domestic innovation as critical for China's long-term competitiveness in artificial intelligence amid ongoing geopolitical tensions1
