METHODS OF FABRICATING INTERCONNECT STRUCTURES CONTAINING VARIOUS CAPPING MATERIALS FOR ELECTRICAL FUSE AND OTHER RELATED APPLICATIONS

摘要

Methods are provided for fabricating interconnect structures containing various capping materials for electrical fuses and other related applications. The method includes forming a first interconnect structure having a first interfacial structure and forming a second interconnect structure adjacent to the first structure. The second interconnect structure is formed with a second interfacial structure different from the first interfacial structure of the first interconnect structure.
