Patent ID: 7977164

Claim:
A repair process for a fuse of a semiconductor memory device comprising: providing a fuse comprising a lower conductive film of a multilayer interconnection formed on a lower structure of a semiconductor substrate, an upper conductive film of the multilayer interconnection spaced apart upward from the lower conductive film to define a predetermined vertical space therebetween and comprising a form not coinciding with that of the upper conductive film, and a first fuse body vertically connecting the upper and lower conductive films to each other; and cutting the first fuse body of the fuse by providing a laser beam on the first fuse body, wherein a plurality of the fuses, each comprising the upper and lower conductive films and the first fuse body, are arranged in plural rows, and wherein the fuse further comprises a second fuse body installed between the plural rows of the fuses, and during the cutting one of the first fuse bodies by the laser beam, the second fuse body protects other first fuse bodies from being damaged.
