Sources: Samsung and SK Hynix are evaluating chipmaking equipment from China's AMEC for possible use at their Chinese factories, as they hedge against US curbs (Reuters)
↗
Samsung and SK Hynix are assessing Chinese chipmaking equipment from AMEC for their factories in China as a contingency against US export restrictions.
This shift signals a strategic pivot for two major semiconductor manufacturers to diversify their supply chains away from reliance on US-controlled technology. For engineers, it means future tooling decisions may be influenced by geopolitical risk rather than purely technical or cost criteria. The move could also accelerate the maturation of China’s domestic equipment ecosystem, altering long-term procurement options.

THE READ
What elseif makes of it.
The evaluation by Samsung and SK Hynix marks a deliberate step to decouple parts of their supply chain from US export controls. Both firms operate large-scale fabs in China, and US restrictions on equipment exports threaten to disrupt production lines. By considering AMEC’s tools, they are testing whether Chinese-made alternatives can meet their technical and yield requirements without violating existing or future US sanctions. This is not a full replacement but a hedging strategy, keeping options open while the regulatory landscape evolves.
Adopting AMEC equipment carries immediate costs beyond the purchase price. Integration with existing fab workflows, retraining staff, and recertifying processes for yield and reliability will require time and capital. There is also the risk of secondary sanctions or future US policy shifts that could penalize firms using Chinese tools for advanced nodes. Engineers will need to weigh these operational and compliance costs against the benefit of supply chain resilience. The decision is as much about risk management as it is about technical performance.
Where this strategy stops working is at the leading edge of semiconductor manufacturing. AMEC’s current portfolio is strongest in etch and deposition tools for mature and mid-tier nodes, not the most advanced processes. If Samsung and SK Hynix are forced to rely on Chinese equipment for cutting-edge production, they may face performance gaps or delays in scaling new nodes. The evaluation is likely focused on older or less sensitive product lines, leaving their most advanced fabs still dependent on US or Japanese suppliers. This creates a tiered supply chain, with different risk profiles for different product segments.
