Abstract
In an embodiment, a semiconductor device includes a first fuse cutting portion in which fuse lines are arranged transversely adjacent to each other, a first runner portion in which runner lines connected to the fuse lines are arranged transversely adjacent to each other but at smaller intervals than those of the fuse lines, and a first connection portion having connection lines between the fuse lines and the runner lines. An insulating barrier layer covers the connection portions so that post-process residues from fuse cutting do not cause electrical shorts between the closely formed runner lines.
Claims8
A semiconductor device comprising:
- a first fuse section including a first fuse cutting portion, a first runner portion, and a first connection portion:
- fuse lines in the first fuse cutting portion arranged transversely adjacent to each other;
- runner lines in the first runner portion connected to the fuse lines, arranged transversely adjacent to each other but at smaller intervals than those of the fuse lines;
- connection lines in the first connection portion between the fuse lines and the runner lines;
- a second fuse section including a second fuse cutting portion that is transversely adjacent to the first runner portion, a second runner portion that is transversely adjacent to the first fuse cutting portion, and a second connection portion interconnecting the second fuse cutting portion and the second runner portion;
- a first insulating barrier layer covering the first and second connection portions and exposing the first and second fuse cutting portions;
- and
- a second insulating barrier layer covering the first and second runner portions.
