    摘要: A technique that ensures suppressing deterioration of a plating quality of a substrate caused by air bubbles accumulated on a lower surface of a membrane is provided. An air bubble removing method of a plating apparatus is an air bubble removing method for removing air bubble in an anode chamber 13 in a plating apparatus 1000 including a plating tank 10 and a substrate holder 30. The air bubble removing method includes: supplying a plating solution Ps from at least one supply port 70 disposed in an outer peripheral portion 12 of the anode chamber to the anode chamber and causing at least one discharge port 71 disposed in the outer peripheral portion of the anode chamber so as to face the supply port to suction the supplied plating solution to form a shear flow Sf of the plating solution along a lower surface on the lower surface 61a of a membrane 61 in the anode chamber.

    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.
