    ASML Faces Domestic Chinese DUV Competition; China Revenue Share Drops

    Question

    ASML Faces Domestic Chinese DUV Competition; China Revenue Share Drops

    Direct answer

    The emergence of a domestic Chinese DUV competitor marks a significant milestone in Beijing's semiconductor self-sufficiency drive. While ASML still holds a monopoly on EUV (Extreme Ultraviolet) technology, the loss of the DUV (Deep Ultraviolet) market in China - which previously accounted for nearly half of revenue - is a structural headwind. The stock's recent dip reflects these geopolitical risks, though the company's growing EUV backlog from non-Chinese customers remains a core valuation support.
