Sources: SMIC plans to use its stock of US and Dutch-made equipment to build 5nm Kirin chips designed by Huawei's HiSilicon for smartphones, despite US curbs
SMIC and Huawei plan to make new 5nm processor, supporting Beijing's goal for advanced semiconductors
Context & Ripple Effects
Huawei's China-made 7nm Kirin chip had already shown that SMIC could supply an advanced smartphone processor, with the Mate 60 Pro teardown providing the clearest evidence of that domestic 7nm manufacturing milestone. Reporting that SMIC used reworked ASML DUV equipment for the effort also framed the constraint: China lacked EUV access but could extend older tools beyond their conventional use case.
The proposed 5nm program is therefore an attempt to turn a one-generation workaround into a repeatable Huawei–SMIC supply path. It matters because the reported plan relies on equipment already installed, making the usefulness and remaining life of that tool base central to both companies' smartphone strategy.
First-order effects
- Huawei's HiSilicon would gain a prospective domestic route to a more advanced Kirin smartphone chip, reducing its dependence on externally sourced leading-edge processors.
- SMIC would devote capacity and its stock of US- and Dutch-made tools to a technically demanding Huawei program, reinforcing Huawei as a strategically important foundry customer.
Second-order effects
- The effort raises the value of installed foreign semiconductor equipment inside China: access restrictions can limit future expansion while leaving existing tool fleets productive for longer.
- Rival Chinese handset makers and chip designers face a clearer incentive to seek domestic foundry alternatives, while overseas equipment restrictions become less decisive as a near-term supply constraint.
Third-order effects
- If SMIC can sustain successive node advances with available equipment, export controls are likely to function more as a constraint on scale, cost and yield than as a complete barrier to advanced Chinese chips.
- The broader shift is toward a more vertically coordinated Chinese semiconductor stack, where design, foundry capacity and state industrial priorities are increasingly aligned around strategic devices.
The trend: This is one data point in China's push to convert constrained access to foreign chipmaking tools into a durable domestic advanced-semiconductor supply chain.
