On March 16, 2026, Reuters reported that China’s second‑largest foundry, Hua Hong Group, is preparing to introduce a 7‑nanometer process for AI chips, with production work underway at its Shanghai-based unit Shanghai Huali Microelectronics (HLMC). The report said Hua Hong has developed a 7nm manufacturing technology suitable for AI processors and is readying a production ramp, which would make it the country’s second domestic foundry at that node after SMIC. If confirmed, the move would strengthen China’s local AI chip supply chain and reduce reliance on overseas capacity for certain AI workloads.
Reuters and a follow‑up report by Sina Finance said Hua Hong plans to use an “n+1” process route and is targeting initial capacity of several thousand wafers per month by the end of 2026. The same reporting says the 7nm process is being prepared at HLMC’s Shanghai fab, signaling a push beyond Hua Hong’s traditional focus on mature nodes and specialty processes into more advanced logic manufacturing. The timeline and scale underline that this is an early ramp rather than full‑scale production, but it would still represent a significant technical step for the company.
7nm ramp would create a second domestic advanced‑node foundry
China currently has only one domestic foundry reported to have produced 7nm‑class chips: Semiconductor Manufacturing International Corp. (SMIC). Reuters and Investing.com both describe Hua Hong’s entry as a potential second source for domestic advanced‑node manufacturing, a status that could matter for local AI chip designers and high‑performance computing customers. A second domestic 7nm player would diversify capacity inside China and reduce single‑supplier dependency at the most advanced node available domestically.
Policy signals add context. China has put semiconductors and AI at the center of industrial planning, as highlighted in China’s 15th Five‑Year Plan boosts AI Plus, semiconductors. Against that backdrop, any incremental domestic capacity at 7nm reads as both a commercial update and a strategic signal.
Early capacity targets and ecosystem testing
Local supply‑chain signals suggest early ecosystem testing. Tech outlet Mydrivers reported that GPU maker Biren Technology has already completed a tape‑out on the 7nm line, an indication that at least one Chinese AI accelerator company is evaluating the process. Tape‑outs do not guarantee mass production, but they are a required step before volume manufacturing and are particularly meaningful for large, complex AI and server‑class chips where yields and performance targets can be demanding.
That experimentation also fits a broader domestic push to secure AI‑chip supply. In related coverage, Dreame’s chip unit said its “Tianqiong” AI chips hit mass production for robotics, illustrating that downstream chip makers are actively scaling. A new 7nm ramp would give those companies more domestic options as they move from design to volume.
Market reaction and global context
Markets reacted quickly to the report. Sina Finance noted that Hua Hong’s A‑share price briefly jumped more than 16% after the Reuters story circulated, while Investing.com highlighted a rally in both the A‑share and H‑share listings and a broader lift across China’s semiconductor sector. The price action reflects how sensitive investors are to any domestic progress on advanced manufacturing nodes and the strategic importance that policy and industry stakeholders attach to that capability.
The global context shows why even a modest domestic ramp matters. TrendForce data for 2025 put global top‑10 foundry revenue at about $169.5 billion, with TSMC holding roughly 70.4% market share and Samsung around 7.1%, while SMIC ranks among the top three. Against that scale, China’s domestic 7nm capacity will remain small relative to the leading‑edge giants, but any incremental output can still help local AI chip designers avoid capacity bottlenecks and shorten supply chains.
Even if Hua Hong reaches its target of several thousand wafers per month, those volumes would be limited compared with the output of leading‑edge fabs in Taiwan and South Korea. But for China’s AI hardware ecosystem, incremental 7nm capacity could be meaningful: it would provide a domestic alternative for design houses that cannot access advanced overseas nodes, and it could support local production of AI accelerators and server chips. The emphasis on an n+1 process also points to a node‑optimization strategy rather than a full node leap, which may help with equipment availability and yield stability during an initial ramp.
What changed, and what to watch next
Follow‑on coverage framed the report as part of China’s broader self‑sufficiency push. Seeking Alpha summarized the Reuters report and echoed the point that Beijing is accelerating domestic semiconductor capabilities, a theme also reflected in Reuters’ emphasis on China’s ramp‑up of self‑reliance. That framing matters because it suggests the market is reading Hua Hong’s 7nm plan not just as a company update, but as a signal about national industrial priorities in advanced chips.
What changed is that a second domestic foundry is now reportedly preparing a 7nm process aimed at AI chips, moving China closer to a multi‑supplier advanced‑node landscape at home. The next milestones to watch are confirmation of production start, additional customer tape‑outs, and whether Hua Hong can meet its end‑2026 capacity target. If those steps proceed, China’s AI chip supply chain will gain a small but strategically important new source of advanced manufacturing.
