Abstract
A semiconductor structure prevents energy that is used to blow a fuse from causing damage. The semiconductor structure includes a device, guard ring, and at least one protection layer. The device is constructed on the semiconductor substrate underneath the fuse. The seal ring, which surrounds the fuse, is constructed on at least one metal layer between the device and the fuse for confining the energy therein. The protection layer is formed within the seal ring, on at least one metal layer between the device and the fuse for shielding the device from being directly exposed to the energy.
