Abstract:
1. A Printed Circuit Board (PCB) comprising: at least one built-in Integrated Circuit (IC) package having a plurality of conductive bumps on an IC, wherein the plurality of conductive bumps are for external electrical connection and the IC package is accommodated within a core layer of a multi-layer PCB by a connection member on the IC; a build-up insulation layer formed on the core layer; and a build-up conductive layer formed on the build-up insulation layer, wherein the connection member is formed between the conductive bumps and a first core conductive layer of the core layer with contact holes in contact with the conductive bumps, and at least one of the conductive bumps are electrically connected to the first core conductive layer through conductor layers formed in at least one of the contact holes, and wherein a via hole is formed through the build-up insulation layer, and the build-up conductive layer is connected to one of the conductive bumps through a conductor layer formed in the via hole and a conductor layer formed in one of the contact holes.
