  • There are many materials which have been studied and developed for being a diffusion barrier against Cu, for example, nitrides of transition metals such as TaN, TiN, TiB2, and so on.
  • Electromigration is a major reliability concern in intergrated circuits due to the aggressive scaling of interconnect dimensions and the increasing current densities at operation.
