Abstract :
This paper demonstrates the existence of dislocation loops and their influence on the kinetics of self-annealing in electroplated Cu film. Plating with higher deposition rate produces more dislocation loops in the Cu film, resulting in faster self-annealing process. Kinetic calculations including this effect give a good correspondence to the experimental observations.
