Abstract
A copper-compatible fuse target is fabricated by forming a copper target structure at the same time that the copper traces are formed. After the copper target structure and the copper traces have been formed, a conductive target, such as an aluminum target, is formed on the copper target structure at the same time that conductive connection portions, such as aluminum pads, are formed on the copper traces. A trench is then etched around the copper target structure and conductive target to form a fuse target.
