  • Patent number: 7241372
    Abstract: A plating apparatus and a plating liquid removing method removes a plating liquid remaining on a substrate-contacting portion, or portions in its vicinity, of a substrate holding member. The plating apparatus comprises a head having a rotatable housing provided with a substrate holding member for holding a substrate, a plating process container, disposed below the head, for holding a plating liquid therein, and a plating liquid removing mechanism for removing plating liquid remaining on the substrate-contacting portion, or the portions in its vicinity, at an inner circumferential edge of the substrate holding member.

  • Patent number: 7166204
    Abstract: A plating apparatus and method which smoothly perform contact of a plating liquid with a surface of the substrate and which can prevent air bubbles from remaining on the surface to be plated. The plating apparatus includes a plating bath containing a plating liquid in which an anode is immersed, a head portion for holding a substrate detachably and bringing a lower surface, to be plated, of the substrate into contact with an overflow surface of the plating liquid held in the plating bath, a drive mechanism for rotating the head portion, and a tilt mechanism for tilting the head portion so that the substrate held by the head portion is inclined relative to a horizontal plane.

  • Publication number: 20060185976
    Abstract: A plating apparatus continuously plates a surface of a substrate with metal and performs its supplementary process in one housing unit. The plating apparatus comprises a cassette stage for placing a substrate cassette thereon, a pre-treatment unit for pre-treating a surface of a substrate, and a plating unit for plating a surface of the substrate pre-treated in the pre-treatment unit. The plating apparatus further comprises a first substrate stage disposed between the cassette stage and the pre-treatment unit, a cleaning and drying unit disposed between the cassette stage and the first substrate stage, a first transfer device, and a second transfer device. The first transfer device transfers a substrate between the substrate cassette, the cleaning and drying unit, and the first substrate stage. The second transfer device transfers a substrate between the first substrate stage, the pre-treatment unit, and the plating unit.

  • Patent number: 6558518
    Abstract: A substrate such as a semiconductor wafer is plated to fill a metal such as copper (Cu) or the like in interconnection grooves defined in the substrate. An apparatus for plating such a substrate has a plating chamber for holding a plating solution, the plating chamber housing an anode that is immersible in the plating solution held by the plating chamber. A plating solution ejector pipe produces an upward jet of plating solution from a plating solution supplied to the plating chamber from an external source, and a substrate holder removably holds a substrate and positions the substrate such that a surface to be plated of the substrate is held in contact with the jet of plating solution. The plating chamber has a plating solution outlet defined in a bottom thereof for discharging a portion of the supplied plating solution via through-holes defined in the anode and/or around the anode out of the plating chamber.
