Abstract

An integrated circuit fuse includes a substantially bar-shaped central region and zones having electrical contacts. The central region includes a thinned zone forming a weak point facilitating fusing of the fuse by increasing the local current density as compared to standard fusing conditions. The thinned zone is preferably obtained by proximity optical effect between the fuse and adjacent dummy elements.
