    ASML Faces Domestic Chinese DUV Competition

    Question

    ASML Faces Domestic Chinese DUV Competition

    Direct answer

    While ASML maintains a monopoly on EUV (Extreme Ultraviolet) systems required for the most advanced chips, its DUV (Deep Ultraviolet) business is under siege. The emergence of a domestic Chinese competitor threatens the remaining 16% of ASML's revenue from the region. This development validates the 'bifurcation' thesis in semiconductors, where China builds a parallel, independent supply chain for mature nodes while the West maintains the lead in advanced logic.
