Abstract: A heat treatment process includes irradiating a substrate including a glass sheet coated on one of its faces with a stack of thin layers, under an atmosphere containing oxygen (O2), with electromagnetic radiation having a wavelength comprised between 500 and 2000 nm, the electromagnetic radiation being emitted by an emitter device placed facing the stack of thin layers, a relative movement being created between the emitter device and the substrate, so as to raise the stack of thin layers to a temperature at least equal to 300° C. for a brief duration shorter than one second, wherein the last layer of the stack, making contact with the atmosphere, called the overcoat, is a metal layer of indium or of an indium-based alloy.
