Abstract
A process for fabricating a wiring board is provided. In the process, a wiring carrying substrate including a carry substrate and a wiring layer is formed. Next, at least one blind via is formed in the wiring carrying substrate. Next, the wiring carrying substrate is laminated to another wiring carrying substrate via an insulation layer. The insulation layer is disposed between the wiring layers of the wiring carrying substrates and full fills the blind via. Next, parts of the carry substrates are removed to expose the insulation layer in the blind via. Next, a conductive pillar connected between the wiring layers is formed. Next, the rest carry substrates are removed.
