Chipmakers find it harder to operate in China but say that doing business there is key to their survival, as the country accounts for roughly a third of sales
Context & Ripple Effects
This story is the latest turn in a three-year arc the coverage has tracked closely: TSMC was already squeezed between Trump-era tech policy and its Chinese customers back in 2020 ([[a:1160957]]), and the 2022 US export controls drew what experts called a dire picture for China's chip and AI ambitions ([[a:1157622]]). What has changed since is that the dependence runs both ways — SEMI put China at 33% of all chip-equipment sales in 2023, and Applied Materials and Lam Research now draw over 40% of sales there by shipping legacy tools the curbs don't touch.
So when chipmakers say China is roughly a third of sales and key to survival even as operating gets harder, it is not a new complaint but a quantified standoff: Western firms cannot afford to leave, and China's heavy-investment self-reliance drive has stumbled through investigations yet keeps pushing to cut US tools ([[a:866677]]).
First-order effects
- Chipmakers face rising compliance and operating friction in China while defending roughly a third of global revenue there — every new restriction converts directly into cost or lost sales on their largest single market.
- Equipment vendors like Applied Materials and Lam Research are already routing around the curbs by boosting shipments of legacy chipmaking tools that fall outside US control, keeping China revenue above 40% of their totals.
Second-order effects
- Every shipment of non-restricted legacy equipment doubles as technology transfer pressure, accelerating China's domestic substitution effort and eroding the future addressable market for US toolmakers.
- Non-US equipment and chip suppliers become the quiet beneficiaries: as American firms operate under tighter scrutiny, Chinese buyers shift procurement toward vendors not bound by Washington's rules.
Third-order effects
- The industry is structurally bifurcating into two stacks — an advanced-node ecosystem aligned with US export controls and a legacy-node ecosystem centered on Chinese demand — with firms' revenue concentration in China making full decoupling economically irrational for either side.
- If China's self-reliance program eventually matures despite its documented setbacks, today's dependence asymmetry inverts: Western chipmakers would face a competitor where they currently book a third of sales.
The trend: Semiconductors are settling into a managed interdependence in which US restrictions tighten operations in China even as China's share of chipmakers' revenue keeps growing.
