Abstract
The semiconductor device which has an electric straight line-like fuse with a small occupying area is offered. A plurality of projecting portions 10f are formed in the position shifted from the middle position of electric fuse part 10a, and, more concretely, are formed in the position distant from via 10e and near via 10d. A plurality of projecting portions 20f are formed in the position shifted from the middle position of electric fuse part 20a, and, more concretely, are formed in the position distant from via 20d and near 20e. That is, projecting portions 10f and projecting portions 20f are arranged in the shape of zigzag.
