  • Publication number: 20120141246
    Abstract: A substrate holding apparatus can meet the request for a smaller-sized compact apparatus while ensuring a sufficient immersion depth of a substrate in a processing liquid. The substrate holding apparatus includes: a substrate holder for supporting a substrate (W) by bringing a peripheral portion of a surface of the substrate (W) into contact with a first sealing member; and a substrate pressing section for lowering relative to the substrate holder so as to press the substrate (W) held by the substrate holder downward, thereby bringing a first sealing member into pressure contact with the substrate (W). The substrate pressing section is provided with a second ring-shaped sealing member which makes pressure contact with an upper surface of a ring-shaped holding section of the substrate holder, thereby sealing the peripheral region of the substrate pressing section.

    Abstract: A plating method and a plating apparatus, which has a plurality of plating units, for plating a substrate. Each of the plating units includes a plating tank for containing a plating solution therein, a water cleaning tank, disposed adjacent to said plating tank for cleaning the substrate with water, a substrate holder for holding the substrate in a vertical orientation, a vertical displacing mechanism for vertically dipping the substrate holder and a substrate held thereby in the plating solution in the plating tank, and a lateral displacing mechanism or a back-and-forth displacing mechanism for moving the substrate holder while holding the substrate in a vertical orientation between the plating tank and the water cleaning tank. The plating unit also includes a loading/unloading station for loading and unloading the substrate, and a transfer device for transferring the substrate between the plating unit and the loading/unloading station.

  • Publication number: 20110203518
    Abstract: A substrate processing method and apparatus can securely carry out a pre-plating treatment that enables uniform plating in the necessary area of the surface of a substrate. The substrate processing method carries out a cleaning treatment and a catalyst-imparting treatment of a surface of a substrate as pre-plating treatments and then electroless plates a metal film on the catalyst-imparted surface of the substrate. The cleaning treatment is carried out in a wider area of the surface of the substrate than that area to which a catalyst is imparted by the catalyst-imparting treatment.
