Abstract: A circuit substrate has an open substrate, a heat-dissipation block, multiple high thermal conductivity members, a first dielectric layer, a second dielectric layer, multiple first heat conductive members, and multiple second heat conductive members. The heat-dissipation block is disposed in the open substrate. Multiple high thermal conductivity members are mounted through the heat-dissipation block. The first dielectric layer exposes a part of one of two surfaces of the heat-dissipation block. The second dielectric layer exposes a part of the other surface of the heat-dissipation block. The first heat conductive members are in contact with the heat-dissipation block exposed from the first dielectric layer. The second heat conductive members are in contact with the part of the heat-dissipation block exposed from the second dielectric layer. Therefore, heat can be transferred quickly via the heat-dissipation block and the high thermal conductivity members to improve heat-dissipating capacity of the circuit substrate.

Abstract: A wiring board and a method of manufacturing the same are provided. The method includes the following steps. A substrate is provided. The substrate is perforated to form at least one through hole. A first conductive layer is integrally formed on a surface of the substrate and an inner wall of the through hole. An etch stop layer is formed on a portion of the first conductive layer on the surface of the substrate and another portion of the first conductive layer on the inner wall of the through hole. A second conductive layer is integrally formed on the etch stop layer and the first conductive layer on the inner wall of the through hole. A plug-hole column is formed by filling with a plugged-hole material in the through hole. The second conductive layer is removed. The etch stop layer is then removed.
