China Chipmaker Hua Hong Readies 7nm Production for AI

Reporting from Singapore, industry developments indicate that China is making significant strides in its pursuit of semiconductor independence. The nation's second-largest chipmaker, Hua Hong Semiconductor Limited, has reportedly developed advanced manufacturing capabilities for 7-nanometer (nm) chips. This advancement, led by its subsidiary Huali Microelectronics, marks a critical milestone in Beijing's strategy to bolster domestic production of artificial intelligence hardware. The group is currently preparing its 7nm process at a facility in Shanghai, positioning itself as the second Chinese firm capable of producing such advanced nodes after SMIC. This technological leap comes at a time when the United States has modified certain export restrictions, allowing NVIDIA Corporation to provide specific AI chips to the region. Despite these shifts, Chinese authorities continue to drive the adoption of homegrown alternatives to reduce reliance on international supply chains. The technical path for this development involves collaboration with major domestic tech entities like Huawei and support from local equipment suppliers such as SiCarrier. While SMIC relies on tools from the Netherlands-based ASML Holding N.V., the specific equipment configuration for the new line remains confidential. Research and development for the 7nm node began last year at the group's Fab 6, which previously focused on more mature 22nm and 28nm technologies. Initial production capacity is projected to reach several thousand wafers per month by the end of the year, with plans for further expansion. Reports suggest that SHANGHAI BIREN TECHNOLOGY -H, a prominent designer of graphics processing units, is already utilizing the 7nm line for tape-out. This partnership provides a vital manufacturing route for the firm, which faced restricted access to global foundries following its inclusion on a trade blacklist. To support these technological upgrades, the parent group recently announced plans to raise approximately 7.56 billion yuan in additional funding.
