Abstract:
Provided are a multilayer board and a method for manufacturing same, in which a different kind of metal layer is formed between an upper metal layer and an interlayer insulating layer, the different kind of metal layer being formed only in a wiring area without being formed in a via area. The multilayer board comprises: a substrate layer; a plurality of first metal layers sequentially stacked on the substrate layer; an interlayer insulating layer formed between two different first metal layers, having a first via hole, and electrically connecting the two different first metal layers through a third metal layer formed in the first via hole; and a second metal layer formed between the upper layer of the two different first metal layers and the interlayer insulating layer.
