Abstract
A packaging substrate is provided, which includes: a core layer having opposite first and second surfaces; two circuit layers formed on the first and second surfaces, respectively; a plurality of conductive through holes penetrating the core layer and electrically connected to the first and second circuit layers; two insulating protection layers disposed on the first and second surfaces of the core layer and the circuit layers; and a carrier attached to one of the insulating protection layers for preventing cracking of the packaging substrate during transportation or packaging.
