Abstract:
1. A method of obtaining a substrate coated on a first face with at least one transparent and electrically conductive thin layer based on at least one oxide, comprising: depositing the at least one thin layer on the substrate; subjecting the at least one thin layer to a heat treatment in which the at least one layer is irradiated with aid of radiation having a wavelength of between 700 nm and 1,300 nm, the radiation being delivered by at least one radiation device placed facing the at least one layer, said radiation device emitting a linear laser beam that simultaneously irradiates all of the width of the substrate, the emitted linear beam forming a laser beam line having a thickness between about 0.004 mm and about 1 mm and a length of at least 5 mm; and creating a relative displacement between the radiation device and the substrate so as to perform the heat treatment of the at least one thin layer, the heat treatment being such that resistivity of at least on layer is reduced during the heat treatment.
