Claim Text:
1. A manufacturing method of a package structure, comprising: providing a substrate, the substrate having an upper surface, a lower surface, and an opening, the upper surface and the lower surface being opposite to each other, the opening communicating the upper surface and the lower surface; configuring an electronic device in the opening of the substrate; laminating an adhesive layer and a patterned metal layer located on the adhesive layer on the lower surface of the substrate, the adhesive layer and the patterned metal layer exposing a bottom surface of the electronic device; forming a heat-dissipating column on the bottom surface of the electronic device exposed by the adhesive layer and the patterned metal layer after laminating the adhesive layer and the patterned metal layer located on the adhesive layer on the lower surface of the substrate, the heat-dissipating column connecting the patterned metal layer and the bottom surface of the electronic device; and respectively laminating a first laminated structure and a second laminated structure on the upper surface of the substrate and the patterned metal layer after forming the heat-dissipating column, the first laminated structure covering the upper surface of the substrate and a top surface of the electronic device, the second laminated structure covering the heat-dissipating column and the patterned metal layer, wherein the first laminated structure comprises at least one first dielectric layer, at least one first patterned metal layer, and at least one conductive via penetrating the at least one first dielectric layer, the at least one first dielectric layer and the at least one first patterned metal layer are sequentially stacked on the upper surface of the substrate, the opening is filled with the at least one first dielectric layer, and the at least one first patterned metal layer is electrically connected to the electronic device through the at least one conductive via.
