Abstract:
A wiring substrate includes a first wiring structure and a second wiring structure. The first wiring structure includes a first insulating layer, which covers a first wiring layer, and a via wiring. A first through hole of the first insulating layer is filled with the via wiring. The second wiring structure includes a second wiring layer and a second insulating layer. The second wiring layer is formed on an upper surface of the first insulating layer and an upper end surface of the via wiring. The second wiring layer partially includes a roughened surface. The second insulating layer is stacked on the upper surface of the first insulating layer and covers the second wiring layer. The second wiring structure has a higher wiring density than the first wiring structure. The roughened surface of the second wiring layer has a smaller surface roughness than the first wiring layer.

Claim (Index 10):
A wiring substrate comprising:\n a first wiring structure; and a second wiring structure stacked on the first wiring structure, wherein the first wiring structure includes:\n a first wiring layer; \n a first insulating layer covering the first wiring layer, wherein the first insulating layer includes a first through hole that extends through the first insulating layer in a thickness-wise direction to expose an upper surface of the first wiring layer; and \n a via wiring including an upper end surface exposed from an upper surface of the first insulating layer, wherein the first through hole of the first insulating layer is filled with the via wiring, \n the second wiring structure includes:\n a second wiring layer including a first wiring pattern, wherein the first wiring pattern is formed on the upper surface of the first insulating layer and the upper end surface of the via wiring; and \n a second insulating layer stacked on the upper surface of the first insulating layer and covering the second wiring layer, \n the second wiring structure has a wiring density that is higher than a wiring density of the first wiring structure, and the first wiring pattern of the second wiring layer comprises:\n a first metal barrier film formed on the upper surface of the first insulating layer and the upper end surface of the via wiring; \n a first metal film formed on the first metal barrier film; and \n a first metal layer formed on the first metal film, \n wherein the first metal layer partially includes a roughened side surface and a roughened upper surface and partially includes a smooth side surface and a smooth upper surface, \n each of the roughened side surface and the roughened upper surface of the first metal layer has a surface roughness that is smaller than a surface roughness of the first wiring layer, and \n the first metal barrier film includes a peripheral portion that projects toward an outer side from the roughened side surface of the first metal layer.
