Recent reporting from Reuters highlights a significant step in China's semiconductor self-sufficiency efforts. Hua Hong Semiconductor, the country's second-largest chipmaker, is preparing to produce 7nm chips at its Fab 6 facility in Shanghai through its foundry arm, Huali Microelectronics. This would make Hua Hong only the second domestic player, after SMIC, capable of 7nm fabrication.
Key details from the report:
\- Development of the 7nm process began last year, supported by domestic equipment suppliers, including those backed by Huawei (such as SiCarrier).
\- Huawei has played a central role in collaborating with Hua Hong on this technology, enabling greater reliance on local tools and reducing dependence on foreign suppliers.
\- Initial production is expected to start at a modest scale (a few thousand wafers per month by the end of 2026), with Biren Technology (a GPU designer previously added to the US Entity List) already using the line for tape-outs.
This progress occurs against the backdrop of longstanding US export controls on advanced AI chips, including Nvidia's H200 series. Although the US administration eased some restrictions earlier this year (allowing case-by-case approvals for H200 exports with conditions and surcharges), Chinese firms have largely opted against purchasing these chips, prioritizing domestic alternatives instead.
The outcome illustrates a clear pattern, restrictions intended to limit China's access to cutting-edge technology have accelerated Beijing's investment in indigenous capabilities. By fostering collaboration between Huawei, Hua Hong, SMIC, and local equipment makers, China is steadily building a more resilient domestic supply chain for semiconductors, particularly those relevant to AI applications.
While China's 7nm nodes remain behind leading global foundries (e.g., TSMC and Samsung, now at 3nm/2nm in volume production), the addition of a second viable 7nm player strengthens redundancy and capacity within the domestic ecosystem.
