Patent ID: 7537677

Claim:
A method of making a coated article including a coating supported by a glass substrate, the method comprising: depositing an infrared (IR) reflecting layer on the substrate; sputtering a ceramic target comprising zinc oxide in forming a first layer comprising zinc oxide on the substrate, where the layer comprising zinc oxide is a dielectric layer and directly contacts the IR reflecting layer and is located above or below the IR reflecting layer; wherein the zinc oxide of the ceramic target is substoichiometric; and wherein during said sputtering of the ceramic target oxygen and inert gas are provided in a sputtering chamber in which the ceramic target is being sputtered and where oxygen makes up no more than 20% of the total gas in the sputtering chamber in which the ceramic target is being sputtered, and wherein the ceramic target comprising zinc oxide is doped with from about 0.5 to 5.0% fluorine.
