A coated article that can be used in applications such as insulating glass (IG) units, so that resulting IG units can achieve high visible transmission of at least 70% (e.g., when using clear glass substrates from 1.0 to 3.5 mm thick), combined with at least one of: (a) SHGC no greater than about 0.

A coated article that can be used in applications such as insulating glass (IG) units, so that resulting IG units can achieve high visible transmission of at least 70% (e.g., when using clear glass substrates from 1.0 to 3.5 mm thick), combined with at least one of: (a) SHGC no greater than about 0.45, more preferably no greater than about 0.40; (b) SC no greater than about 0.49, more preferably no greater than about 0.46; (c) chemical and/or mechanical durability; (d) neutral transmissive color such that transmissive a* is from −5.0 to 0 (more preferably from −3.5 to −1.5), and transmissive b* is from −2.0 to 4.0 (more preferably from 1.0 to 3.0); and (e) neutral reflective color from the exterior of the IG unit (i.e., Rg/Rout) such that reflective a* is from −3.0 to 2.0 (more preferably from −2.0 to 0.5), and reflective b* is from −5.0 to 1.0 (more preferably from −4.0 to −1.0). In certain example non-limiting embodiments, coated articles herein comprise: substrate/TiOx/ZnOx/Ag/NiCrOx/SnOx/ZnOx/Ag/NiCrOx/SnOx/SixNy.

The invention claimed is: 1. A method of making a coated article including a coating supported by a glass substrate, the method comprising:providing a glass substrate;sputtering a coating on the glass substrate, the coating comprising at least the following layers on the glass substrate:a layer comprising zinc oxide;a layer comprising silver over and contacting the layer comprising zinc oxide; anda layer comprising nickel chromium oxide over and contacting the layer comprising silver, wherein the layer comprising nickel chromium oxide is sputter-deposited in an atmosphere comprising oxygen gas so as to be oxidized throughout its thickness as deposited;a dielectric layer provided over at least the layer comprising nickel chromium oxide;another layer comprising zinc oxide;another layer comprising silver located over and contacting the another layer comprising zinc oxide;wherein there are no more than two layers comprising silver in the coating; andat least one dielectric layer provided over the another layer comprising silver; andwherein the coating has a sheet resistance (Rs) of no greater than 5.0 ohms/square, and the coated article has a visible transmission of at least 70%.
