摘要: According to an embodiment, a substrate holder holds a rectangular substrate and performs electrolytic plating on the substrate. The substrate holder includes a first holding member and a second holding member clamping the substrate between the first holding member and it and having a contact which contacts a peripheral part of the substrate and supplies an electric current to the substrate. The second holding member includes an opening defining a region where an electric field is formed and, at a position farther from the substrate than the opening, a shielding part protruding closer to an inner side than the opening and shielding the peripheral part of a surface of the substrate. The shielding part has a frame shape having a predetermined shielding width in the peripheral part of the substrate, and has, at a corner part thereof, a discontinuous part having a smaller shielding width than surroundings.

摘要: Provided are a plating method, an insoluble anode and a plating apparatus capable of reducing consumption of an additive in a plating solution, when plating a substrate including a via or a hole for forming a through electrode. The plating method includes the steps of preparing a substrate including a via or a hole for forming a through electrode, preparing a plating solution tank that is divided, by a diaphragm, into an anode tank in which an insoluble anode is disposed and a cathode tank in which the substrate is disposed, and electroplating the substrate with an anode current density when plating the substrate in the plating solution tank being equal to or more than 0.4 ASD and equal to or less than 1.4 ASD.

摘要: A substrate holder holds a polygonal substrate Wf. A plating bath accommodates the anode holder and the substrate holder. The anode and the substrate are immersed in a plating solution in the plating bath. A control device controls a current flowing between the anode and the substrate. The substrate holder has power feed members placed along respective sides of the polygonal substrate, and there are a plurality of groups of the sides, each group including at least one side, at least one side being different between the groups. The control device can control, on a group-by-group basis, a current to be supplied to the power feed members.
