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 18):
A method for fabricating a substrate having an electrical interconnection structure, comprising the steps of:\n providing a substrate body having a plurality of conductive pads and a first passivation layer formed thereon, wherein the first passivation layer is formed with a plurality of first openings for exposing at least a portion of each of the conductive pads; forming a second passivation layer on the first passivation layer, wherein the second passivation layer has a plurality of second openings for exposing the exposed portion of each of conductive pads; forming a first metal layer on the expose portion of each of the conductive pads via the second openings of the second passivation layer, wherein the first metal layer is embedded in the first and the second passivation layers without being protruded from the second passivation layer; and forming a second metal layer on the first metal layer, wherein the second metal layer is protruded from the second passivation layer.
