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

摘要

PROBLEM TO BE SOLVED: To readily blow a fuse portion by raising Joule heat, when an overcurrent flows in the fuse portion and a current density increases locally at other portion where an electric field concentrates.;SOLUTION: The current fuse includes the fuse portion 20 disposed on a substrate; and a conductive portion 16, placed in an overlying layer above the fuse portion 20 or an underlying layer between the substrate and the fuse portion 20, having the same potential as that of one portion of the fuse portion 20, when energizing the fuse portion 20, and extending from the one portion side of the fuse portion 20 to the overlying layer, above or the underlying layer below another portion of the fuse portion 20 with the potential differing from that of the one portion.;COPYRIGHT: (C)2012,JPO&INPIT
