Abstract

A method for improving the quality of a system of layers deposited on a substrate such as glass is provided, in which, the system of layers have an oxide-based surface layer, in particular n-type semi-conductor oxides such as SnO.sub.x, in which the surface layer is subjected to IR irradiation to provide a stabilization of the layer equivalent to or better than with a 48-hour exposure to the air.
