Semiconductor device and method of blowing fuse thereof
View Patent ↗A semiconductor device comprises an active region including a core circuit forming region and a buffer forming region, and a fuse element forming region arranged on a corner of the active region and to be able to be electrically fused. It is possible to arrange the fuse element without forming the fuse in the core circuit forming region by arranging the fuse element forming region at the corner of the active region.
1. A semiconductor device comprising:
an active region including a core circuit forming region and a buffer forming region;
a fuse element forming region arranged on a corner of the active region and to be able to be electrically fused; and
a wire for fusing connected to a fuse of the fuse element forming region, said wire for fusing being formed in plural wire layers in an upper layer of the corner,
wherein said active region and said fuse element are in a same semiconductor chip.
2. The semiconductor device according to claim 1 further comprising:
a pad forming region to be arranged around the buffer forming region,
wherein a pad formed near the corner of the active region is electrically connected to a fuse formed in the fuse element forming region.
3. The semiconductor device according to claim 2 wherein at least one of pads electrically connected to the fuse is electrically connected to an external terminal.
