Abstract
A coated article is provided with at least one infrared (IR) reflecting layer. The IR reflecting layer may be of silver or the like. In certain example embodiments, a titanium oxide layer is provided over the IR reflecting layer, and it has been found that this surprisingly results in an IR reflecting layer with a lower specific resistivity (SR) thereby permitting thermal properties of the coated article to be improved.
Claims13
A method of making a coated article, the method comprising:
- providing a glass substrate;
- sputter-depositing a dielectric layer on the substrate;
- sputter-depositing a layer comprising zinc oxide on the glass substrate;
- sputter-depositing an infrared (IR) reflecting layer comprising silver on the glass substrate and over the dielectric layer and over the layer comprising zinc oxide, wherein the IR reflecting layer comprising silver directly contacts the layer comprising zinc oxide, and wherein the layer comprising zinc oxide is between at least the dielectric layer and the IR reflecting layer comprising silver;
- sputter-depositing a layer comprising an oxide of Ni and Cr on the glass substrate and over and directly contacting the IR reflecting layer comprising silver;
- depositing a layer comprising titanium oxide on the glass substrate over and directly contacting the layer comprising the oxide of Ni and Cr, and over the IR reflecting layer comprising silver, in a manner so that the layer comprising titanium oxide as deposited is more oxided at a location therein further from the IR reflecting layer than at a location closer to the IR reflecting layer.
