By terminating fuse material on a "corrosion stop" material, e.g., silicon, materials previously unusable due to atmospheric exposure and subsequent corrosion after fuse blowing are now used. This makes possible the use of upper level conductors for fuses with consequent larger insulation thickness between fuse and substrate. Therefore, more energy may be expended in blowing fuses without danger of making a connection to the substrate. A wider fuse blowing energy window or use of very high melting point materials for fuses are advantages of the structure.
