Abstract:
A substrate processing apparatus for plating a surface of a substrate, comprising:a pretreatment unit for pretreatment of the surface of the substrate; a plating unit for plating the substrate after the substrate has been pretreated by said pretreatment unit; and a transfer robot for transferring the substrate between said pretreatment unit and said plating unit; wherein said pretreatment unit comprises: a substrate holder for holding a substrate with the surface of the substrate facing downward, a first liquid spraying section for spraying a first liquid toward the surface of the substrate when held by the substrate holder, a second liquid spraying section for spraying a second liquid toward the surface of the substrate when held by the substrate holder, and a separation section that prevents the first liquid and the second liquid from being mixed when sprayed; wherein said separation section comprises: a first cup for receiving the first liquid when sprayed; a vertically movable second cup having an opening that opens upwardly and is disposed inside said first cup for receiving the second liquid when sprayed; and a separator that covers said opening of said second cup when the first liquid is sprayed toward the surface of the substrate.
