Abstract: The act of blowing an unpassivated electrical fuse (for example, fuse 405) using a laser can result in the splattering of the fuse material and result in electrical short circuits. A blast barrier (for example blast barrier 406) formed around an area of the fuse that is blown by the laser helps to contain the splattering of the fuse material. The blast barrier may be formed from the same material as the fuses themselves and therefore, can be created in the same fabrication step.
