Abstract:
1. A method for forming a semiconductor device comprising the steps of: forming a first dielectric film overlying a substrate; embedding an electrode pad and a pair of fuse terminals in a surface portion of said first dielectric film, wherein the electrode pad is formed in a first common layer with the pair of fuse terminals; forming a refractive metal on said first dielectric film, wherein the refractive metal is in direct contact with said pair of fuse terminals and said electrode pad; patterning said refractive metal to form a fuse element in contact with said pair of fuse terminals and to form a first protective film on, and in direct contact with, said electrode pad, wherein the first protective film is formed in a second common layer with the fuse element; forming a second dielectric film on: said first dielectric film, said first protective film in direct contact with said electrode pad and said fuse element in direct contact with said fuse terminals; and forming a first opening in said second dielectric film to expose at least a portion of said first protective film on the electrode pad, wherein the first opening formed in said second dielectric film does not expose said fuse element in contact with said pair of fuse terminals.
