Patent ID: 7566481

Claim:
A method of making a coated article for use in a window, the method comprising: providing a glass substrate; and forming an anti-etch layer on the glass substrate that is resistant to attacks by fluoride-based etchant(s) using each of at least one sputtering target and at least one ion source so that ions in an ion beam from the ion source impinge on a layer-forming surface along with material sputtered from the sputtering target, wherein the anti-etch layer comprises one or more of: silicon carbide nitride, hydrogenated silicon carbide nitride, zirconium oxycarbide, zirconium carbide, hydrogenated zirconium oxycarbide, and/or hydrogenated zirconium carbide; and using the glass substrate with at least the anti-etch layer thereon as a window of a car, train, subway car, bus or building; wherein the glass substrate with at least the anti-etch layer thereon has a visible transmission of at least about 30%.
