Abstract: A process for the manufacture of a material including a glass or glass-ceramic substrate provided, on at least one of its faces, with a stack of thin layers including a functional layer based on indium tin oxide, the process including successively depositing the functional layer and then, under a pressure of at most 2.5 ?bar, an oxygen barrier layer by magnetron cathode sputtering on the at least one face of the substrate.

Abstract: The subject of the invention is a glazing unit comprising a glass substrate (1) equipped on one of its faces, intended to form face 1 of said glazing unit in the use position, with a thin-film multilayer comprising, from the substrate (1), a film (2) of a transparent electrically conductive oxide, an intermediate film (3) having a refractive index lying in the range from 1.40 to 1.55 and having an optical thickness Y, and a photocatalytic film (4) the optical thickness X of which is at most 50 nm, said optical thicknesses X and Y, expressed in nanometers, being such that: 110·e?0.025X?Y?135·e?0.
