Abstract

The high-resolution electron backscatter diffraction technique and transmission electron microscopy were applied to study microstructure in the overburden layer, in upper and bottom parts of as-deposited as well as subsequently annealed nanoscale (100 nm width) copper wires. It was shown that the temperature interval 100oC-200oC should be seen as a transition period of microstructure evolution in damascene copper lines.
