Claim 13:
14. A method of reducing the sheet resistance of a coated article, comprising:
(a) applying a first underlayer film over at least a portion of a substrate, wherein the first underlayer film comprises a first refractive index material, wherein the first underlayer is in direct contact with the substrate;
(b) applying a second underlayer film over at least a portion of the first underlayer film, wherein the second underlayer film comprises a second refractive index material and wherein the first refractive index material has a refractive index greater than the second refractive index material;
(c) applying a first transparent conductive oxide layer over at least a portion of the second underlayer film;
(d) applying an embedded film over at least a portion of the first transparent conductive oxide layer, wherein the embedded film has a thickness in the range of 15 nm to 30 nm, wherein the embedded film comprises a third refractive index material, wherein the third refractive index material has a refractive index within 10% of the first refractive index material, and wherein the third refractive index material has a refractive index greater than the second refractive index material; and
(e) applying a second transparent conductive oxide layer over at least a portion of the embedded film.
