Has China gotten its hands on the world's most important machine?
The Economist explores whether China has gained access to the most advanced chip-manufacturing technology, until now considered a Western monopoly. At stake is extreme ultraviolet lithography, without which cutting-edge chips cannot be made. A breakthrough would undermine Western export controls.
At the heart of the analysis is extreme ultraviolet lithography (EUV), the most complex and expensive machine in semiconductor manufacturing, so far made only by the Dutch group ASML and meant to be kept away from China thanks to Western export controls. The Economist examines indications that China could be on the way to developing its own capability or obtaining one by other means, which would shake the foundation of America's technological containment. If Beijing clears this hurdle, it could produce cutting-edge chips independently and neutralize the effect of the sanctions, a strategic turning point in the tech race. Opposing voices point out that in this precision class there are still enormous hurdles between a prototype and industrial mass production. The article comes from the liberal Economist and remains deliberately cautious in assessing the actual level of maturity, as hard evidence is naturally difficult to obtain. The outcome will help decide whether the West's chip blockade holds.
