FIELD OF THE INVENTION

The present invention relates to a package apparatus and manufacturing method thereof, and more particularly, to a semiconductor package apparatus and method for manufacturing the same.

BACKGROUND OF THE INVENTION

With the design trend in electronic devices is toward lighter, smaller, thinner but more functional devices with performance requirements continuing to increase, device manufacturers increasingly need specialty integrated circuit (IC) solutions for allowing billions of miniature electronic components to be densely packed in a small area. Thus, device manufacturers come up with innovative packaging techniques for embedding electronic components in a substrate while allowing shorter traces between the electronic components and the substrate. In addition, the layout area is increased by the use of built-up technique as the technology advances for achieving lighter, smaller, thinner and more functional high-performance devices.

Generally, most high-end chips are packaged by flip chip (FC) process, especially by a chip scale package (CSP) process, as those high-end chips are primarily being applied in smart phones, tablet computers, network communication devices, and notebook computers, whichever is generally operating under high-frequency and high-speed condition and required to be packed in a thin, small and light-weighted semiconductor package. As for the carrier for packaging, the popular design nowadays includes: small pitches between lines, high density, thin-type design, low manufacture cost, and high electrical characteristic.

Please refer toFIG. 1, which shows a conventional fiberglass substrate packaging structure. InFIG. 1, the fiberglass substrate packaging structure with molded interconnection system1includes a bump bonding structure10A and a wire bonding structure10B, and is structured for allowing a conductive pillar layer110A to be embedded inside a fiberglass substrate100A, whereas the fiberglass substrate100A can be a bismaleimide triazine (BT) substrate or a FR-5 substrate. In addition, there is further a protection layer120A and conductive elements140A being disposed on the conductive pillar layer110A while simultaneously allowing the bump bonding of certain internal components130A to be disposed on the conductive pillar layer110A, and a molding compound layer150A to be disposed on the fiberglass substrate100A. Similarly, the other conductive pillar layer110B is also embedded inside the other fiberglass substrate100B, and the fiberglass substrate100B can be a bismaleimide triazine (BT) substrate or a FR-5 substrate. Furthermore, there is further a protection layer120B and conductive elements140B being disposed on the conductive pillar layer110B while simultaneously allowing the wire bonding of certain internal components130B to be disposed on the conductive pillar layer110B, and a molding compound layer150B to be disposed on the fiberglass substrate100B.

It is noted that the aforesaid fiberglass substrate packaging structure with molded interconnection system1is formed by forming through mold via (TMV) on the molding compound layer150A of the bump bonding structure10A so as to be used for enabling the conductive elements140A to connect electrically to conductive elements140B of the wire bonding structure10B.

However, the aforesaid conventional fiberglass substrate packaging structure is very costly for using a fiberglass substrate as its substrate and the thin-type fiberglass substrate can be easily deformed and wrapped. The conventional substrate including fiberglass will increase the difficulty of processing for laser via so that it cannot fit the need of fine pitch, and therefore make the wiring more troublesome; and as the blind/buried vias in the aforesaid multi-layered metal laminated structure are formed by the repetition of a laser via method, such repetition can be a complex and time consuming process. Since the electrical connections between the plural bonding structures in the package structure are achieved through the TMV whereas such TMV should be fabricated by the use of a laser via process, the whole package fabrication process can be very costly.

SUMMARY OF THE INVENTION

The present invention provides a package apparatus and the manufacturing method thereof, by which a molding compound layer is used as the major material in the manufacturing of a coreless substrate. The package module can be fabricating by the embedding of chips inside the coreless substrate to replace the function of a convention fiberglass substrate, and after a plurality of such package modules are formed, they are laminated and interconnected and packaged into a multi-chip package.

In an embodiment, a package apparatus comprises a first package module, a second package module and a plurality of conductive elements. The first package module comprises a first molding compound layer, a first conductive pillar layer, a first internal component, and a first protection layer. The first conductive pillar layer is disposed in the first molding compound layer and is formed with a first surface and a second surface arranged opposite to the first surface. The first internal component is electrically connected to the first conductive pillar layer while being disposed in the first molding compound layer. The first protection layer is disposed on the first molding compound layer and the first surface of the first conductive pillar layer.
