China's second-largest chipmaker, Hua Hong Semiconductor, is about to start producing 7-nanometer chips at its Shanghai facility, and it's doing it with domestic equipment. That's a problem for anyone who thought U.S. export controls were going to keep Chinese chipmakers stuck in the technology stone age.
According to a Reuters report, Hua Hong's Fab 6 facility is preparing to produce 7nm chips through its foundry arm, Huali Microelectronics. The key detail here: they're using equipment from domestic suppliers, many of them backed by Huawei. Initial production is expected to start at a modest scale, a few thousand wafers per month by the end of 2026, but the fact that they can do it at all is the story.
This matters because it directly contradicts the entire logic of the U.S. export ban. The Biden administration restricted sales of advanced AI chips and chipmaking equipment to China on the theory that cutting off access to cutting-edge tools would slow down Chinese semiconductor development. The idea was simple: if you can't buy the machines, you can't make the chips.
Except that's not what happened. Instead of slowing down, Chinese companies accelerated their investment in domestic alternatives. Huawei, which was cut off from U.S. technology years ago, helped build out local equipment suppliers like SiCarrier. State-backed firms like SMIC and now Hua Hong have focused on developing workarounds. The result: China is building a self-sufficient semiconductor supply chain, which is exactly what the export controls were supposed to prevent.
From an investment standpoint, this has major implications. U.S. chip equipment companies like Applied Materials, Lam Research, and ASML have lost access to the Chinese market for their most advanced products. That's a huge revenue hit. Meanwhile, Chinese chipmakers are proving they don't need Western equipment to hit 7nm, a node that's more than good enough for most AI applications.
