Abstract:
A method for fabricating a substrate having an electrical interconnection structure is provided, which includes the steps of: providing a substrate body having a plurality of conductive pads and first and second passivation layers sequentially formed on the substrate body and exposing the conductive pads; forming a seed layer on the second passivation layer and the conductive pads; forming a first metal layer on each of the conductive pads, wherein the first metal layer is embedded in the first and second passivation layers without being protruded from the second passivation layer; and forming on the first metal layer a second metal layer protruded from the second passivation layer. As such, when the seed layer on the second passivation layer is removed by etching using an etchant, the etchant will not erode the first metal layer, thereby preventing an undercut structure from being formed underneath the second metal layer.

Claim (Index 28):
A method for fabricating a substrate having an electrical interconnection structure, comprising the steps of:\n forming a first resist layer on a substrate body having a plurality of conductive pads and forming a second resist layer on the first resist layer, wherein the first resist layer is formed with a plurality of first openings and the second resist layer is formed with a plurality of second openings in communication with the first openings, the first openings are larger in size than the second openings, and at least a portion of the conductive pads are exposed from the first and second openings; forming a first metal layer in each of the first openings of the first resist layer, wherein the first metal layer has an extending portion; forming a second metal layer on the first metal layer, wherein the second metal layer is positioned in the corresponding second openings and does not cover the extending portion of the first metal layer; removing the first resist layer and the second resist layer; and removing the extending portion of the first metal layer.
