Reliability of Copper Metallization - NASA
2001.9.15 Copper Copper exhibits many of the same problems of the other two noble metals, but has the distinct advantage in that its resistivity is substantially better than Au and only slightly worse than Ag. This coupled with the diffusion through dielectrics, much faster than Al, but not as fast as Au or Ag makes Cu the best compromise.
