Claim:
1. A method for manufacturing a package apparatus, comprising the steps of: providing a metal carrier composed of a first side and a second side that are arranged opposite to each other; forming a first photoresist layer on the first side of the metal carrier; forming a first dielectric material layer on the second side of the metal carrier; forming a first wiring layer on the second side of the metal carrier while allowing the first dielectric material layer to be disposed within a specific portion of the first wiring layer; forming a second photoresist layer on the first dielectric material layer and the first wiring layer; removing a portion of the second photoresist layer for exposing the first wiring layer; forming a first conductive pillar layer on the first wiring layer; removing the first photoresist layer and the second photoresist layer; forming a first buffer layer covering the first dielectric material layer, the first wiring layer, the first conductive pillar layer and the second side of the metal carrier; exposing a first end of the first conductive pillar layer; forming a second wiring layer on the first buffer layer and the first end of the first conductive pillar layer; forming a protection layer on the first buffer layer and the second wiring layer; and removing the metal carrier.
