Abstract:
1. A plating method of plating a surface of a substrate, the method comprising: providing a plating cell having an anode therein; arranging a resistor body above the anode in the plating cell so as to form a space between a lower surface of the resistor body and the plating cell; supplying a plating solution into the space formed between the lower surface of the resistor body and the plating cell so as to fill the space with the plating solution; supplying a plating solution to an upper surface of the resistor body from a plurality of plating solution supply sections arranged around the resistor body, each of the plating solution supply sections being configured to discharge the plating solution toward a center of the resistor body such that a raised portion of the plating solution is created in the center of the resistor body; lowering the substrate with the surface to be plated facing downwardly until a center of the surface to be plated initially comes into contact with the plating solution, and then a contact area between the surface to be plated and the plating solution broadens toward a periphery of the surface to be plated, and then a space between the surface to be plated and the upper surface of the resistor body becomes filled with the plating solution; and applying a voltage between the surface to be plated and the anode to plate the surface to be plated of the substrate.
