Abstract

Official abstract text for this publication.

According to one embodiment, a plating apparatus for electroplating a substrate including a non-pattern area is provided. The plating apparatus includes a plating tank for holding the plating solution, an anode configured to be connected to a positive electrode of a power supply, and a paddle configured to move in the plating tank to stir the plating solution held in the plating tank. The paddle is configured such that at least a part of the non-pattern area of the substrate is constantly blocked when the paddle is viewed from the anode while the paddle is stirring the plating solution.

First claim

Opening claim text (preview).

What is claimed is: 1. A plating apparatus for electroplating a substrate including a non-pattern area, the plating apparatus comprising: a plating tank for holding a plating solution; an anode configured to be connected to a positive electrode of a power supply; and a paddle configured to move in the plating tank to stir the plating solution held in the plating tank, wherein the paddle is configured such that at least a part of the non-pattern area of the substrate is constantly blocked when the paddle is viewed from the anode while the paddle is stirring the plating solution, wherein the paddle includes an outer peripheral portion and a rib, the paddle being configured such that at least a part of the non-pattern area of the substrate is constantly blocked by the rib when the paddle is viewed from the anode while the paddle is stirring the plating solution, the rib is configured to be attachable to and removable from the outer peripheral portion. 2. The plating apparatus according to claim 1 , wherein a position where the rib is attached to the outer peripheral portion is adjustable. 3. The plating apparatus according to claim 1 , wherein the rib extends in a direction where the paddle moves when the paddle stirs the plating solution. 4. The plating apparatus according to claim 1 , wherein the rib is configured to project toward a side of the anode from the outer peripheral portion.
