Patent ID: 7994544

Claim:
A semiconductor device, comprising: a substrate; an insulating layer formed on said substrate; a fuse element having a first thickness and being brought into a blow state by a current supplied thereto and being embedded into said insulating layer; and first and second conductive walls that are substantially perpendicular to said substrate and are embedded into said insulating layer to sandwich said fuse element therebetween with an intervention of a part of said insulating layer, each of said first and second conductive walls being formed with a second thickness that is larger than said first thickness, wherein said insulating layer includes first and second insulating films, said fuse element being formed between said first and second insulating films, each of said first and second conductive walls including a first portion formed between said first and second insulating films, wherein said first portion is composed of the same material as said fuse element and has a same thickness as said fuse element, and wherein said first and second insulating films each extending in a single continuous plane between said first and second conductive walls.
