摘要:
A printed circuit board includes: a first metal layer; an organic insulating layer covering at least a portion of the first metal layer and having a via hole exposing at least a portion of an upper surface of the first metal layer; a first seed metal layer disposed on an upper surface of the organic insulating layer; a second seed metal layer disposed on the first seed metal layer and extending onto a wall surface of the via hole and the exposed upper surface of the first metal layer; and a second metal layer disposed on the second seed metal layer and filling at least a portion of the via hole, wherein the first seed metal layer includes a first sputtering layer including titanium (Ti), and the second seed metal layer includes an electroless plating layer.
