Patent ID: 7671443

Claim:
An integrated circuit fuse structure comprising: an insulating structure having a fuse region and a wire region adjacent to the fuse region; at least one fuse pattern extending on both the fuse region and the wire region in a first direction; an insulating layer pattern on the insulating structure to cover the at least one fuse pattern on the wire region, the insulating layer pattern having an opening portion that exposes the fuse region of the insulating structure; and at least one fence on the fuse region within the opening portion of the insulating layer pattern to be overlapped with the at least one fuse pattern and extending in a second direction substantially perpendicular to the first direction, the at least one fence being spaced apart from a sidewall of the opening portion of the insulating layer pattern, the fence preventing at least some fractures of the fuse pattern from spattering, wherein the fractures are generated when the fuse pattern is cut.
