CURRENT FUSE, SEMICONDUCTOR DEVICE, AND METHOD OF BLOWING A CURRENT FUSE

摘要

A current fuse includes: a fuse portion that is disposed on a substrate; and a conductive portion that is placed in an overlying layer above the fuse portion or an underlying layer between the substrate and the fuse portion, has the same potential as that of one portion of the fuse portion when a current is passed through the fuse portion, and extends apart from the fuse portion from the one portion side of the fuse portion as far as an overlying layer above or an underlying layer below another portion of the fuse portion whose potential differs from that of the one portion.
