Claim Text:
1. A package substrate structure, comprising: a first selective-electroplating epoxy compound, comprising a plurality of cavities, a first surface and a second surface opposite to the first surface, wherein the cavities are disposed on the first surface, and the first selective-electroplating epoxy compound comprises non-conductive metal complex; a first patterned circuit layer, directly disposed on the first surface, wherein the first selective-electroplating epoxy compound exposes a top surface of the first patterned circuit layer, and the top surface of the first patterned circuit layer is lower than the first surface or coplanar with first surface; a plurality of metal studs, respectively disposed in the cavities and protruding from the first surface, wherein the first patterned circuit layer is electrically connected with the corresponding metal studs; a plurality of second patterned circuit layers, directly disposed on the second surface, wherein the first selective-electroplating epoxy compound exposes a top surface of each of the second patterned circuit layers, and the top surface of each of the second patterned circuit layers is lower than the second surface or coplanar with the second surface; and a plurality of first conductive vias, disposed in the first selective-electroplating epoxy compound to electrically connect the second patterned circuit layers to the corresponding metal studs.
