    摘要: A method for manufacturing a circuit board structure is provided. First, a first circuit layer is formed on a carrier. Then, a first dielectric layer is formed on the carrier and the first circuit layer. Thereafter, at least one first hole is formed in the first dielectric layer to expose a portion of the first circuit layer. Then, a second dielectric layer is formed on the first dielectric layer and the first circuit layer. Thereafter, at least one trench and at least one second hole are formed in the second dielectric layer, in which the trench exposes a portion of the first dielectric layer, and the second hole exposes the portion of the first circuit layer. The second hole is disposed in the first hole. Then, a metal layer is formed to fill the trench and the second hole.

    摘要: A wiring substrate includes a first wiring layer with a wiring pattern and a metal foil. A first insulating layer includes a first through hole having a first end facing the metal foil and a second end. A second wiring layer includes a first opening having a diameter smaller than the second end. A second insulating layer includes a second through hole having a third end facing the wiring pattern and a fourth end. A third wiring layer includes a second opening having a diameter smaller than the fourth end. A first via is filled in the first opening, the first through hole, and a first recess, in the metal foil, having a diameter greater than the first end. A second via is filled in the second opening, the second through hole, and a second recess, in the wiring pattern, having a diameter greater than the third end.
