Patent ID: 8389394

Claim:
Method for making a semiconductor package, comprising: (a) providing a substrate having a surface, wherein the surface has at least one first pad and at least one second pad; (b) forming a first passivation layer on the surface of the substrate, wherein the first passivation layer covers the surface of the substrate and exposes the first pad and the second pad; (c) forming a first metal layer on the first passivation layer, wherein the first metal layer is electrically connected to the second pad and has an opening to expose the first pad; (d) forming a second passivation layer on the first metal layer, wherein the second passivation layer exposes the first pad and part of the first metal layer; (e) forming a fourth metal layer on the second passivation layer; and (f) patterning the fourth metal layer, so as to form a second metal layer and a third metal layer, wherein the second metal layer is electrically connected to the first pad, and the third metal layer is electrically connected to the first metal layer.
