China’s 3nm Chip Shocks the West—How SMIC Beat Sanctions and Built Its Most Advanced Tech Ever.

China's largest chipmaker, SMIC (Semiconductor Manufacturing International Corporation), has taken a bold leap forward with the successful establishment of a new 5-nanometer chip production line in Shanghai—using existing U.S. and Dutch equipment despite global export restrictions. But what has truly shaken the tech world is SMIC’s unprecedented breakthrough: manufacturing 3-nanometer chips without access to ASML’s EUV lithography machines.

This feat, accomplished through advanced multi-patterning and deep ultraviolet (DUV) lithography, marks a major turning point in the global semiconductor race. It not only challenges the long-standing dominance of TSMC, Samsung, and Intel but also signals China’s rapid climb toward technological self-sufficiency. SMIC’s ability to innovate under pressure, bypass geopolitical roadblocks, and compete at the highest level highlights a seismic shift in the balance of global tech power.

In Q1 2024, SMIC ranked third in global chip foundry revenue, and its expanding portfolio—from 28nm display drivers to 3nm high-performance chips—proves it’s not just catching up but actively redefining the industry. As the U.S. and its allies scramble to contain China's rise in the semiconductor sector, SMIC's achievements suggest the old order is being disrupted.

The implications are global: from supply chain resilience and national security to economic competitiveness. As SMIC scales its capabilities, it could make high-end chips more affordable, accessible, and less reliant on the West. The global tech competition just got a new frontrunner—and it’s not backing down.
