Peculiarities of segregation of impurities at the boundaries of a thin film separating two different solid materials are considered. Theoretical and numerical analysis of kinetics of impurity redistribution within the film and at the boundaries has been carried out. Subject to the energy of interaction of the impurity atoms with the boundaries, the initial impurity concentration and temperature, the criteria of realization of different variants of segregation were ascertained.
