Samsung and SK Hynix Test Chinese Chip Equipment Supplier AMEC

What happened

Samsung Electronics and SK Hynix began evaluating chipmaking equipment from China's Advanced Micro-Fabrication Equipment (AMEC) at their Chinese manufacturing facilities approximately two years ago. The testing represents a contingency plan rather than a commitment to large-scale adoption of Chinese tools. Both South Korean memory chipmakers continue to rely heavily on Western equipment suppliers, particularly Applied Materials and Lam Research for etching tools, but are assessing alternatives in response to evolving US export restrictions. Washington withdrew validated end-user status from both companies in 2025 before issuing annual import licences for 2026, creating uncertainty around long-term equipment support. Samsung's NAND memory plant in Xi'an and SK Hynix's facilities in Dalian and Wuxi could face production risks if future restrictions extend beyond new equipment purchases to include servicing, maintenance, and replacement parts for installed Western machinery.

Why it matters

For Lam Research and other Western semiconductor equipment suppliers with significant China exposure, these evaluations represent a strategic shift in customer contingency planning. Applied Materials generated $8.53 billion in China revenue, making the region a critical market. While immediate commercial deployment of AMEC equipment remains uncertain due to lengthy qualification processes, successful validation would provide Samsung and SK Hynix with credible negotiating leverage and alternative supply options. Industry research firm TechInsights estimates Chinese tools offer a 20% to 30% price discount compared to Western equivalents, potentially pressuring incumbent suppliers on pricing, contract terms, and market share even if overall chip equipment demand remains strong. The situation illustrates how US export controls designed to restrict China's semiconductor capabilities may inadvertently accelerate evaluation and adoption of domestic Chinese equipment suppliers by global chipmakers operating in China.

Bigger picture

The reported equipment testing highlights broader tensions in the global semiconductor supply chain as geopolitical considerations increasingly influence commercial relationships. US semiconductor equipment makers face a complex dynamic: policies intended to limit China's technological advancement are encouraging international customers to diversify away from exclusive reliance on Western suppliers. If AMEC secures supply contracts with major memory manufacturers, it would mark significant commercial validation for China's semiconductor equipment industry and strengthen confidence in domestic manufacturing capabilities. For Western equipment suppliers, the challenge extends beyond direct competition to protecting maintenance and service revenue streams, which provide recurring income and create switching costs that traditionally reinforced customer relationships. The memory chipmakers' focus on maintaining operational flexibility rather than capacity expansion suggests they prioritise production continuity over aggressive technology upgrades in their Chinese operations.

What to watch

Monitor whether Samsung and SK Hynix complete qualification processes for AMEC equipment and any announcements of commercial deployment at their Chinese facilities. Track future US export control policy developments, particularly any restrictions targeting maintenance services, spare parts, or support for previously installed semiconductor manufacturing equipment. Watch for pricing pressure or market share shifts in China for Western equipment suppliers, especially in etching tools where Lam Research and Applied Materials hold strong positions. Observe whether other international chipmakers with Chinese operations begin similar evaluations of domestic Chinese equipment suppliers as contingency planning becomes standard practice.
