Abstract

Disclosed herein is a coreless substrate having filled via pads and a method of manufacturing the same. Insulating layers are formed on both sides of a build-up layer, and via-pads are embedded in the insulating layers such that the via-pads are flush with the insulating layers. The via pads are not separated from a substrate, and thus reliability of the pads is increased. Flatness of bumps is increased, and thus bonding of flip chips becomes easy.
