A process for manufacturing at least one substrate, especially transparent glass substrates, each provided with a thin-film multilayer comprising an alternation of“n”metallic functional layers especially of functional layers based on silver or a metal alloy containing silver, and of“(n+1)”antireflection coatings, with n being an integer≧3, each antireflection coating comprising at least one antireflection layer, so that each functional layer is positioned between two antireflection coatings, said thin-film multilayer being deposited by a vacuum technique, said multilayer being such that the thicknesses of two functional layers at least are different and the thicknesses of the functional layers have a symmetry within the multilayer relative to the center of the multilayer.
