Abstract
A circuit carrier board includes a first build-up layer structure, a substrate, an adhesive layer, and a conductive structure. The first build-up layer includes a plurality of first dielectric layers and a plurality of first circuit layers original stacked. The substrate includes a base and a second build-up layer structure disposed on the base. The second build-up layer structure includes a plurality of second dielectric layers and a plurality of second circuit layer original stacked. A top most layer of the second circuit layers is exposed outside of the second dielectric layers. The conductive structure penetrates through the first dielectric layers, the first circuit layers and the adhesive layer, and contacts with the top most layer of the second circuit layers. The conductive structure electrical connects the first circuit layers to the second circuit layers. A manufacturing method of the circuit carrier board is also provided.
