Abstract:
A flip chip type semiconductor device having pad and fuse areas, comprising:an interlayer insulation layer formed on a semiconductor substrate; a passivation layer formed on said interlayer insulation layer; at least one first metal line formed in a given region of said passivation layer in said pad area; at least a pair of second metal lines formed in a given region of said passivation layer in said fuse area; a pad covering a portion of said first metal line; a fuse covering said pair of second metal lines and said passivation layer there between, said fuse being formed of a layer of the same material as said pad; a polyimide layer over the surface of said semiconductor substrate including said pad and said fuse, said polyimide layer being in contact with and surrounding side and top surfaces of said pad and said fuse, said polyimide layer having a pad opening that exposes said pad; and an under-bump metal layer pattern and a bump sequentially stacked on said exposed pad.
