ELECTROMIGRATION INDUCED HILLOCK DYNAMICS ON THE INTERCONNECT SURFACE

Four Fold Crystal Symmetry, {100} Planes in FCC


When the tilt angle changes to 60°, the surface becomes very unstable, and the oscillatory waves on lee as well as on windward sides start to appear with increasing in intensities. In later stages, the form of these waves transforms into the sawtooth shape having rather sharp windward front. A typical situation is illustrated in Figure, where χ=25 and A =10. The intensity of the electron winds doesn’t affect the overall evolution behavior.
