Claim 13:
14. A method for manufacturing a chip package structure, comprising:
providing a substrate, the substrate comprising a first region and a second region surrounding the first region;
fabricating a wiring layer on the substrate by a film forming process, wherein the wiring layer comprises at least one metal wire, wherein at least part of a metal wire of the at least one metal wire is in contact with the substrate, and wherein the at least one metal wire overlaps with the second region in a direction perpendicular to the substrate;
providing a chip with a first conductive bump arranged on a side of the chip;
attaching the wiring layer and the chip with the first conductive bump, wherein the chip corresponds to the first region, and wherein the first conductive bump is electrically connected to a metal wire of the at least one metal wire; and
fabricating a second conductive bump, wherein the second conductive bump is electrically connected to a metal wire of the at least one metal wire;
wherein the chip comprises a photosensitive region located at the side of the chip facing towards the substrate and opposite to the first region, and wherein the photosensitive region does not overlap with the metal wire in the wiring layer.
