The quantum electronic-transport model of ultrathin-metal-film conductivity is developed within the scope of the Boltzmann theory. The fluctuations of metal-film boundary drastically change electron energy spectrum in thin metal film. These changes determine the conditions of electron scattering in the mode of quantum charge transfer. Size dependence of metal-film conductivity is calculated within the framework of the developed model. Within the scope of our theoretical approach, we can estimate the average amplitude of surface fluctuations in continuous metal films, which has a good agreement with STM surface investigation. The minimum thickness for manifestation of metallic conductivity in CoSi$_{2}$ films is calculated within the framework of the percolation model.

Key words: thin metal films, surface and grain boundary scattering.
