Abstract
A structure and design structure is provided for interconnect structures containing various capping materials for electrical fuses and other related applications. The structure includes a first interconnect structure having a first interfacial structure and a second interconnect structure adjacent to the first structure. The second interconnect structure has second interfacial structure different from the first interfacial structure.
