    摘要: A wiring board includes an insulating layer covering upper and side surfaces of a first interconnect layer, a via hole penetrating the insulating layer and reaching the first interconnect layer, a second interconnect layer filling the via hole and extending on the insulating layer, and a cavity provided in the first interconnect layer, communicating with the via hole and extending outside than a lower end of an inner side surface of the via hole in a plan view. The second interconnect layer includes a first seed layer provided on the insulating layer, a second seed layer continuously covering upper and inner side surfaces of the first seed layer, the inner side surface of the via hole, and surfaces of the insulating layer and the first interconnect layer exposed inside the cavity, and an electrolytic plating layer provided on the second seed layer thicker than the first seed layer.

    摘要: A semiconductor package includes a substrate. A pattern layer is disposed on a first surface of the substrate. The pattern layer includes a plurality of pads and a plating wire positioned between adjacent pads of the plurality of pads. A first protection layer is disposed on the first surface of the substrate to cover the pattern layer and expose the plurality of pads. At least one pad of the plurality of pads is physically separated from the plating wire.
