Claim Text:
1. A method of making a heat treated coated article adapted to be used in window, the method comprising: heat treating a coated substrate comprising a substrate, a transparent conductive oxide (TCO) layer on the substrate, a gettering layer on the substrate over and in direct contact with the TCO layer, wherein the gettering layer comprises carbon and fluorine so as to getter oxygen during said heat treating and help dope the TCO layer with F to improve conductivity, and a protective film on the substrate over at least the TCO layer and the gettering layer, wherein the protective film includes a release layer and an oxygen barrier layer where the release layer and the oxygen barrier layer are of different material and/or different stoichiometry relative to each other, wherein the heat treating comprises heating at least the substrate to temperature(s) of at least 500 degrees C.; during said heat treating of the coated substrate with the TCO layer and the gettering layer and the protective film thereon, the protective film protects the TCO layer so that the TCO layer does not lose a significant amount of electrical conductivity and does not lose a significant amount of visible transmission during said heat treating so that the coated article is to be used in a window, and the gettering layer getters oxygen and provides fluorine for doping the TCO layer to improve conductivity thereof; and exposing the protective film to a release liquid and removing at least part of the protective film during and/or after said heat treating, before the window is formed.
