A Fuse Box of A Semiconductor Device and Fabrication Method Thereof

摘要

A semiconductor fuse box includes a fuse structure and a protective structure disposed between the fuse structure and an integrated circuit structure. The protective structure has at least one irregular side surface. The protective structure (which may also include a pad formed there-under) extends beyond a bottom of the fuse structure. Such an irregular side surface and such an extension of the protective structure minimize propagation of damaging energy to the adjacent integrated circuit structure when a laser beam is directed to the fuse structure.
