Abstract
A coated article is provided which may be heat treated (e.g., thermally tempered) in certain instances. In certain example embodiments, an interlayer of or including a metal oxide such as tin oxide is provided under an infrared (IR) reflecting layer so as to be located between respective layers comprising silicon nitride and zinc oxide. It has been found that the use of such a tin oxide inclusive interlayer results in significantly improved mechanical durability, thermal stability and/or haze characteristics. In certain example embodiments, a zinc oxide inclusive layer is provide over an IR reflecting layer in order to improve thermal stability. A zirconium oxide overcoat may also be provided in certain example instances.

28. A coated article comprising a coating supported by a glass substrate, the coating comprising:
-
a first layer comprising zinc oxide located over and contacting a first layer comprising tin oxide, so that the first layer comprising tin oxide is located between and contacting a first layer comprising silicon nitride and the first layer comprising zinc oxide; a second IR reflecting layer comprising silver located over and contacting the first layer comprising zinc oxide; a contact layer located over and contacting the second IR reflecting layer; another layer comprising metal oxide comprising tin oxide and/or zinc oxide located over and contacting the contact layer; and at least another dielectric layer comprising nitride located over at least the another layer comprising metal oxide. - View Dependent Claims (29, 30, 31, 32, 33, 34)
