Abstract:
An apparatus for plating a metal film onto a surface of a seed layer of a substrate, for cleaning the substrate and the metal film, and for etching the metal film, comprising:a plating section having a plating device for plating a metal film onto a surface of a seed layer of a substrate; a cleaning section having a cleaning device, said cleaning device including (i) a rotation mechanism for holding and rotating the substrate with the metal film plated thereon facing upwardly, and (ii) at least one first nozzle for ejecting an etching solution only onto a peripheral portion of the metal film for removing the peripheral portion of the metal film and a peripheral portion of the seed layer; and a robotic mechanism for transporting the substrate with the metal film plated thereon from said plating section to said cleaning section.
