For years, the semiconductor industry has operated with one unquestioned assumption. When it came to the world's most sophisticated lithography machines used to manufacture chips, there is only one Dutch company, ASML. This assumption has suddenly been challenged. Reports that China has begun mass-producing its first domestically developed immersion deep ultraviolet (DUV) lithography machines have rattled investors, triggered a sharp selloff in semiconductor stocks across Asia and reignited debate over whether Beijing's campaign for technological self-sufficiency is beginning to produce tangible results. For long, the US has used export controls over ASML machines as a lever against China.
The development is significant not because it immediately threatens ASML's global dominance but because it represents another milestone in China's long-term strategy of reducing dependence on Western technology. Industry experts, however, caution that manufacturing a handful of lithography machines is only the beginning. Turning them into reliable tools capable of supporting high-volume chip production remains a far greater challenge. But the development indicates China is breaking free of Western tech dependence in semiconductors.
