Claim 16:
17. A method for forming a chip package, comprising:
providing a substrate, the substrate having a first surface and a second surface opposite the first surface, wherein the substrate comprises an image sensing device adjacent to the first surface of the substrate;
forming a first opening and a second opening surrounding the first opening in the substrate;
forming a first isolation portion of an electrical isolation structure in the second opening of the substrate, and forming a second isolation portion of the electrical isolation structure on the second surface of the substrate, wherein the second isolation portion extends from the first isolation portion; and
forming a first conductive portion of a first conductive structure in the first opening of the substrate, wherein the first conductive portion has a recess, and the second isolation portion has a third opening corresponding to the recess, so that the first conductive portion extends over the second surface of the substrate from the recess and the third opening.
