Coated article with low-E coating including zirconium oxide and/or zirconium silicon oxynitride and methods of making same
First Claim
1. A coated article including a coating supported by a glass substrate, the coating comprising from the glass substrate outwardly:
- a first dielectric layer comprising silicon nitride;
a first contact layer;
an infrared (IR) reflecting layer comprising silver located on the substrate over at least and contacting the first contact layer;
a second contact layer located over and contacting the IR reflecting layer, the second contact layer having a thickness of less than or equal to 11 angstroms;
a second dielectric layer comprising silicon nitride located over and contacting the second contact layer; and
an overcoat dielectric layer comprising one or more of zirconium oxynitride and zirconium silicon oxynitride located over and contacting the second dielectric layer comprising silicon nitride, and wherein the overcoat dielectric layer is doped with Y.

Abstract
This application relates to a coated article including at least one infrared (IR) reflecting layer of a material such as silver or the like in a low-E coating. In certain embodiments, at least one layer of the coating is of or includes zirconium oxide (e.g., ZrO2) or zirconium silicon oxynitride (e.g., ZrSiOxNy). When a layer comprising zirconium oxide or zirconium silicon oxynitride is provided as the uppermost or overcoat layer of the coated article (e.g., over a silicon nitride based layer), this results in improved chemical and heat stability in certain example embodiments. Coated articles herein may be used in the context of insulating glass (IG) window units, vehicle windows, or in other suitable applications such as monolithic window applications, laminated windows, and/or the like.
