Claim 17:
18. The method for manufacturing a chip package structure according to claim 14, wherein the substrate comprises a first pad, and wherein the second conductive bump is electrically connected to one of the at least one metal wire through the first pad;
wherein the method further comprises, before fabricating the second conductive bump:
coating a plastic encapsulation material and the plastic encapsulation material encapsulating the chip and the wiring layer;
curing the plastic encapsulation material to form a plastic encapsulation pre-layer; and
perforating the plastic encapsulation pre-layer with a hole to form an encapsulation layer, the hole exposing the first pad; and
wherein said fabricating the second conductive bump comprises:
fabricating the second conductive bump in the hole, wherein the second conductive bump comprises a first end and a second end that are connected to each other, wherein the second end is embedded in the encapsulation layer, and wherein the first end is exposed outside the encapsulation layer.
