Abstract:
1. A method for manufacturing a pad terminal for a semiconductor device comprising the steps of: forming a first pad on a substrate using a first metal; forming a second pad covering the first pad using a second metal; forming a protection layer over the second pad; forming a plurality of pad contact holes over the second pad through the protection layer exposing a plurality of exposed portions of a surface of the second pad; removing the plurality of exposed portions of the second pad using the plurality of pad contact holes as a mask thereby exposing a plurality of exposed portions of the first pad; and forming a pad terminal comprising a conductive material and connected to the plurality of exposed portions of the first pad and a plurality of sides of the second pad through the plurality of contact holes, wherein the step of removing the plurality of exposed portions of the second pad is separate from the step of forming the plurality of pad contact holes.
