<p>An IC fuse (20) has central branch arms (22, 23) intersecting at a current focusing zone (24) for local current density increase to facilitate fuse blowing. An IC fuse (20), formed by etching a polysilicon or metal layer, comprises central tracks (21) of which the ends include areas (32, 33, 35, 36) provided with electrical contacts (40, 41) to which is applied a potential difference for blowing the fuse. The novelty is that the central tracks (21) form two or more shunt-connected arms (22, 23) intersecting at a zone (24) forming a blowing current focal point to facilitate fuse blowing by increasing the local current density. An Independent claim is also included for an IC including the above fuse.</p> |
