    ASML Faces Domestic Chinese Competition in DUV Lithography

    Question

    ASML Faces Domestic Chinese Competition in DUV Lithography

    Direct answer

    The emergence of a Chinese-made DUV system marks a critical milestone in China's semiconductor self-sufficiency drive. While ASML still holds a monopoly on the most advanced EUV machines required for sub-5nm chips, the loss of the DUV market in China removes a significant revenue floor. Export restrictions have already halved ASML's China exposure, making the company more dependent on TSMC and Intel's EUV roadmaps.
