How China's chip industry is aiming for self-sufficiency and cutting down on US tools; SEMI estimates China represented 33% of all chip equipment sales in 2023

Context & Ripple Effects
China's equipment push extends a longer effort to localize semiconductor supply chains: companies were already auditing suppliers to replace US imports, while industry development had emphasized high-demand basic chips such as microcontrollers and power-management devices.
The reported equipment share makes this consequential beyond a single chip segment. It connects procurement policy, tool retrofits and domestic capacity expansion into a more coordinated attempt to reduce exposure to foreign toolmakers and export restrictions.
First-order effects
- Chinese chipmakers adding capacity face a reported requirement to source at least half of their equipment domestically, directing near-term demand toward local tool suppliers; the rule is not publicly documented.
- US equipment vendors and ASML's older DUV installed base face reduced dependence from Chinese customers, while retrofits of older DUV machines may preserve some Chinese production options despite controls on newer technology.
Second-order effects
- Domestic equipment makers gain a larger home-market test bed, which can improve their ability to qualify tools across Chinese fabs; foreign suppliers may have to compete more on the equipment and service still permitted.
- If Chinese fabs can extend older lithography tools' usefulness, export controls may shift from limiting purchases of leading-edge systems toward constraining the maintenance, components and know-how needed to sustain installed equipment.
Third-order effects
- A durable domestic-procurement mandate would turn China's unusually large equipment market into an industrial-policy lever, creating a more regionally segmented semiconductor-tool supply chain rather than a single globally optimized one.
- The pattern reinforces a second-source strategy: self-sufficiency can advance unevenly, with mature and high-volume chip categories localizing sooner than the most advanced manufacturing capabilities.
The trend: China's semiconductor strategy is evolving from import substitution in chips toward building a domestic manufacturing-tool ecosystem that can operate with less reliance on US-linked technology.
