Patent ID: 8284561

Claim:
A package structure, comprising: a first laminate structure having a first double-layered sheet and a first metal layer disposed below the first double-layered sheet, wherein the first double-layered sheet consists of a first dielectric layer and a second metal layer, the first and second metal layers are separated by the first dielectric layer and the first dielectric layer is sandwiched between the first and second metal layers; a second laminate structure having at least a cavity therein, wherein the second laminate structure consists of a third metal layer and a second dielectric layer disposed on the third metal layer; an interlayer joining the first laminate structure and the second laminate structure, wherein the first metal layer is joined to a surface of the interlayer and the second dielectric layer of the second laminate structure is joined to the opposite surface of the interlayer; a plurality of bonding pads, located within the at least cavity and on the first metal layer; a plurality of plated-through hole structures, extending through the first laminate structure, the interlayer and the second laminate structure; at least an electronic component, electrically connected to and mounted on the plurality of the bonding pads; and an encapsulant, filling up the at least cavity and encapsulating the at least electronic component.
