Abstract
A process for obtaining an item including a substrate made of glass or glass ceramic coated on at least one portion of at least one of its faces with a stack of thin-layers including no silver layers and including at least one thin layer of a transparent electrically conductive oxide, the process including: a step of depositing the stack, in which step the thin layer of a transparent electrically conductive oxide and at least one thin homogenizing layer are deposited, the thin homogenizing layer being a metal layer or a layer based on a metal nitride other than aluminum nitride, or a layer based on metal carbide; then a heat treatment step in which the stack is exposed to radiation.
