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 22):
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 plurality of wiring patterns that are formed on the upper surface of the first insulating layer; 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 each of the plurality of wiring patterns includes:\n a metal barrier film formed on the upper surface of the first insulating layer; \n a metal film formed on the metal barrier film; and \n a metal layer formed on the metal film, \n wherein an entire side surface of the metal film is a roughened side surface having a surface roughness that is smaller than a surface roughness of the first wiring layer, \n an entire upper surface of the metal layer is a roughened upper surface having a surface roughness that is smaller than the surface roughness of the first wiring layer, \n an entire side surface of the metal layer is a roughened side surface having a surface roughness that is smaller than the surface roughness of the first wiring layer, and \n the metal barrier film of each of the plurality of wiring patterns of the second wiring layer includes a peripheral portion that projects toward an outer side from the roughened side surface of the metal film and the roughened side surface of the metal layer.
