In examples, a package comprises a semiconductor die having a device side and a bond pad on the device side, a conductive terminal exposed to an exterior of the package, and an electrical fuse. The electrical fuse comprises a conductive ball coupled to the bond pad, and a bond wire coupled to the conductive terminal. The bond wire is stitch-bonded to the conductive ball.

Methods, systems, and apparatuses for preventing corrosion between dissimilar bonded metals. The method includes providing a wafer having a plurality of circuits, each of the plurality of circuits having a plurality of bond pads including a first metal; applying a coating onto at least the plurality of bond pads; etching a hole in the coating on each of the plurality of bond pads to provide an exposed portion of the plurality of bond pads; dicing the wafer to separate each of the plurality of circuits; die bonding each of the plurality of circuits to a respective packaging substrate; and performing a bonding process to bond a second, dissimilar metal to the exposed portion of each of the plurality of bond pads such that the second, dissimilar metal encloses the hole in the coating of each of the plurality of bond pads, thereby enclosing the exposed portion.
