Query: Monte Carlo simulation of electromigration phenomena in metallic lines   The electromigration (EM) of metallic lines is studied in terms of
competition between two percolative processes taking place in a random resistor
network. The effects associated with the transport of mass and with the
consequent growth of the internal stress are accounted for by stochastic
generation and recovery of voids, driven by the external current. Monte Carlo
simulations enable us to investigate within a unified theoretical framework a
variety of relevant aspects of EM degradation as: damage patterns, the
distribution of the time to failures, early stage resistance change in the
presence of compositional effects, Black's law, geometrical effects, etc. A
general agreement is found with the experimental findings.
