A two-dimensional cross-sectional poly-lattice kinetic Monte Carlo (2DCSP-KMC) model has been developed for simulation of the electrodeposition of polycrystalline copper on either a copper or gold substrate. The model has proved capable of capturing the effects of the deposition parameters, including the applied electrode potential, the concentration of Cu2+ ions and the temperature on the resultant deposit microstructure, the evolution of the grain density, the grain size, the variance of grain size and the grain boundary misorientation distribution. Three unit shapes namely the funnellike, columnar and pyramidal shapes, resulting from the competition between the growth of a grain and its neighbouring grains, are abstracted from a variety of morphology of individual grains to describe the effects of the deposition parameters on the deposit microstructure. The fundamentals of the dependence of these effects on substrate have been discussed and ascribed to the competition amongst the possible KMC events at each KMC step.
