Abstract

Certain example embodiments of this invention relate to articles including anticondensation coatings that are exposed to an external environment, and/or methods of making the same. In certain example embodiments, the anticondensation coatings may be survivable in an outside environment. The coatings also may have a sufficiently low sheet resistance and hemispherical emissivity such that the glass surface is more likely to retain heat from the interior area, thereby reducing (and sometimes completely eliminating) the presence condensation thereon. The articles of certain example embodiments may be, for example, skylights, vehicle windows or windshields, IG units, VIG units, refrigerator/freezer doors, and/or the like.

First claim

What is claimed is:

1. A vehicle windshield comprising:
first and second glass substrates of the vehicle windshield;
wherein the first and second glass substrates of the vehicle windshield are coupled together;
a coating comprising a plurality of thin film layers provided on the first glass substrate, the plurality of thin film layers including, in order moving away from the first glass substrate:
(a) a first dielectric layer comprising silicon nitride;
(b) a second dielectric layer comprising silicon oxynitride;
(c) a layer comprising indium-tin-oxide (ITO) 75-175 nm thick,
(d) a third dielectric layer comprising silicon nitride, and wherein the third dielectric layer comprising silicon nitride is located over and directly contacting the layer comprising indium-tin-oxide so that the layer comprising indium-tin-oxide is located between at least the first glass substrate and the third dielectric layer; and
(e) a layer comprising aluminum oxide, wherein the layer comprising aluminum oxide is an uppermost layer of the coating and is the layer of the coating farthest from the first glass substrate;

wherein the coating is not located between the first and second glass substrates.
