Claim Text:
1. A method of making a coated article, the method comprising: depositing a release layer comprising zinc oxide on a glass substrate, wherein at least a layer comprising carbon is located between the glass substrate and the release layer comprising zinc oxide; plasma treating the layer comprising zinc oxide including ZnO—Zn cermet with at least oxygen ions to provide an ion beam treated layer comprising zinc oxide and to transform at least part of the ZnO—Zn cermet to a more stable ZnOx; depositing an oxygen barrier layer on the glass substrate over the plasma treated layer comprising zinc oxide; and wherein a protective film comprising the plasma treated layer comprising zinc oxide and the oxygen barrier layer are for protecting the layer comprising carbon during subsequent heat treatment in order to prevent significant burnoff of the layer comprising carbon.
