Abstract

A method for forming a fuse includes forming an interconnection pattern and a fuse pattern on a substrate using a damascene process. A passivation layer is formed on a surface of the substrate over the interconnection pattern and the fuse pattern. Then, the passivation layer is patterned to form a pad opening that exposes a portion of the interconnection pattern. A metal pad is formed on the interconnection pattern in the pad opening. A portion of the metal pad extends over the passivation layer. The passivation layer on the fuse pattern is partially etched to form a fuse opening.
