Chinese researchers have achieved early progress in producing 3-nanometre chips using older lithography technology, bypassing the need for advanced extreme ultraviolet (EUV) machines blocked by US sanctions. This development signals a concrete step in Beijing’s strategy to decouple its semiconductor supply chain from Western equipment restrictions, particularly those targeting Dutch giant ASML.
Breaking the Lithography Bottleneck
The breakthrough centres on pushing semiconductor processing nodes below the 3-nm threshold without relying on the state-of-the-art EUV tools currently unavailable to China. Under existing export control rules, ASML is barred from selling its most advanced machines to Chinese manufacturers, creating a significant hardware gap. Researchers have now demonstrated that alternative methods can achieve similar precision using older generation equipment.
This achievement marks the latest iteration in China’s broader drive to chart an independent path for advanced chipmaking. The nation has faced persistent pressure from US export restrictions designed to slow its technological rise. By circumventing the need for EUV lithography, Chinese engineers are reducing their dependency on a single critical choke point in the global supply chain.
The move has direct implications for the Asian technology sector, where manufacturing hubs are closely monitoring equipment availability. Singapore and neighbouring economies that serve as critical nodes in semiconductor logistics and design will watch these developments closely. A shift in lithography standards could alter the demand for specific types of manufacturing equipment and maintenance services across the region.
Chinese authorities have not yet detailed the exact yield rates or commercial viability of these 3-nm chips. However, the confirmation of early strides suggests that the theoretical barrier to advanced node production without EUV is lower than previously assumed. This could accelerate investment in alternative lithography techniques, such as multi-patterning with existing deep ultraviolet (DUV) tools.
The restriction on ASML machines has forced Chinese firms to innovate rapidly. Domestic equipment makers are now racing to fill the gap left by Western exports. The success of these researchers provides a technical validation for those domestic efforts, potentially boosting confidence among local investors and state-backed funds.
For global chipmakers, this development introduces a new variable in supply chain planning. If Chinese production becomes more viable without EUV, the competitive landscape for advanced semiconductors could shift. Companies operating in Asia may need to adjust their technology deployment strategies to account for a potentially bifurcated global standard.
The next phase will involve scaling these processes from laboratory settings to mass production. Researchers must now prove that these older-lithography methods can maintain consistency and yield rates comparable to EUV-produced chips. Until then, the technology remains in the early stages of commercial application.
Stakeholders in the semiconductor industry should monitor upcoming announcements from Chinese research institutes and state-owned enterprises. The transition from experimental success to industrial scale will determine whether this breakthrough translates into tangible market share or remains a technical curiosity.
