Abstract:
1. A packaging substrate having a heat-dissipating structure, comprising: a core layer with a first surface having a first metal layer and an opposite second surface having a second metal layer, and with at least a first cavity penetrating the core layer and the first metal layer so as to expose the second metal layer from the first cavity, also at least a second cavity penetrating the core layer and the second metal layer so as to expose the first metal layer from the second cavity; a plurality of semiconductor chips each having an active surface with a plurality of electrode pads thereon and an opposite inactive surface, wherein the semiconductor chips are received in the first cavity and the second cavity, and attached to the second metal layer and the first metal layer, respectively, by the inactive surfaces; build-up circuit structures respectively disposed on the first metal layer and the second metal layer as well as the semiconductor chips, and having a plurality of conductive vias electrically connecting to the electrode pads of the semiconductor chips; and at least a heat-dissipating through hole penetrating the core layer and the build-up circuit structures, and connecting the first metal layer and the second metal layer.
