Abstract:
A circuit carrier board structure includes a first substrate, a second substrate, an adhesive layer, and a plurality of contact pads. The first substrate includes a first surface and a second surface, and also includes a plurality of first build-up layers sequentially stacked. The first build-up layers include a first dielectric layer and a first circuit layer. The second substrate includes a third surface and a fourth surface, and also includes a plurality of second build-up layers sequentially stacked. The second build-up layers include a second dielectric layer and a second circuit layer. The second surface is combined to the third surface. The connection pads are on the first surface and electrically connected to the first circuit layer. The first substrate is electrically connected to the second substrate. A manufacturing method of the circuit carrier board structure is also provided.
