Patent ID: 8704101

Claim:
A package barrier comprising: a substrate having an upper surface, a lower surface opposite to the upper surface, and an opening communicating the upper surface and the lower surface; an electronic device disposed inside the opening of the substrate, the electronic device having a top surface and a bottom surface opposite to each other; a first insulation layer disposed on the upper surface of the substrate, the first insulation layer filling the opening and having a plurality of first blind holes, the first blind holes exposing a portion of the top surface of the electronic device; a first patterned metal layer disposed on the first insulation layer, the first patterned metal layer exposing a portion of the first insulation layer; a second insulation layer disposed on the lower surface of the substrate, the second insulation layer filling the opening and having a plurality of second blind holes, the second blind holes exposing a portion of the bottom surface of the electronic device; a second patterned metal layer disposed on the second insulation layer, the second patterned metal layer exposing a portion of the second insulation layer; a heat-dissipation channel penetrating the first insulation layer, the first patterned metal layer, the substrate, the second patterned metal layer, and the second insulation layer; a third metal layer filling the first blind holes and the second blind holes and covering an inner wall of the heat-dissipation channel, wherein the third metal layer connects the first patterned metal layer and the second patterned metal layer; and a heat-conducting device disposed inside the heat-dissipation channel.
