A coated article is provided that may be used as a vehicle windshield, insulating glass (IG) window unit, or the like. An ion beam is used to treat an infrared (IR) reflecting layer(s) of such a coated article. Advantageously, this has been found to improve sheet resistance (Rs) properties, emittance, solar control properties, and/or durability of the coated article.

The invention claimed is: 1. A coated article including a glass substrate supporting a coating, wherein the coating comprises: at least one dielectric layer; an IR reflecting layer comprising Ag and/or Au provided on the substrate, the IR reflecting layer being located over at least the at least one dielectric layer; at least one additional layer provided on the substrate over at least the IR reflecting layer; and wherein the IR reflecting layer has an argon and/or krypton content at an upper portion thereof which is greater than that at a lower portion thereof. 2. The coated article of claim 1, wherein the IR reflecting layer is substantially free of oxygen in at least a portion thereof, and is ion beam treated. 3. The coated article of claim 1, wherein the IR reflecting layer is substantially metallic or metallic. 4. The coated article of claim 1, wherein the coated article includes multiple dielectric layers located between the IR reflecting layer and the substrate. 5. The coated article of claim 1, wherein the coated article has a visible transmission of at least 70% and a sheet resistance (Rs) of no greater than 5.0 ohms/square. 6. A coated article including a glass substrate supporting a coating, wherein the coating comprises: at least one dielectric layer; an IR reflecting layer comprising Ag and/or Au provided on the substrate, the IR reflecting layer being located over at least the at least one dielectric layer; at least one additional layer provided on the substrate over at least the IR reflecting layer; wherein the IR reflecting layer at least one of: (a) comprises silver and has a majority compressive stress, and/or (b) has an argon and/or krypton content at an upper portion thereof which is greater than that at a lower portion thereof; and wherein the IR reflecting layer is graded with respect to argon and/or krypton content, so that an upper portion of the IR reflecting layer has a higher argon and/or krypton concentration than does a lower portion of the IR reflecting layer. 7. The coated article of claim 6, wherein the IR reflecting layer is graded with respect to argon content, so that an upper portion of the IR reflecting layer has a higher argon concentration than does a lower portion of the IR reflecting layer. 8. The coated article of claim 6, wherein the IR reflecting layer is graded with respect to krypton content, so that an upper portion of the IR reflecting layer has a higher krypton concentration than does a lower portion of the IR reflecting layer. 9. The coated article of claim 6, further including another IR reflecting layer located over at least said IR reflecting layer comprising Ag and/or Au. 10. A coated article including a glass substrate supporting a coating, wherein the coating comprises: at least one dielectric layer; an IR reflecting layer comprising Ag and/or Au provided on the substrate, the IR reflecting layer being located over at least the at least one dielectric layer; at least one additional layer provided on the substrate over at least the IR reflecting layer; wherein the IR reflecting layer at least one of: (a) comprises silver and has a majority compressive stress, and/or (b) has an argon and/or krypton content at an upper portion thereof which is greater than that at a lower portion thereof; and wherein an upper portion of the IR reflecting layer has an argon and/or krypton concentration at least 10% higher than that of a lower portion of the IR reflecting layer. 11. The coated article of claim 10, wherein the upper portion of the IR reflecting layer has an argon concentration at least 10% higher than that of the lower portion of the IR reflecting layer. 12. The coated article of claim 10, wherein the upper portion of the IR reflecting layer has a krypton concentration at least 10% higher than that of the lower portion of the IR reflecting layer. 13. The coated article of claim 10, further including another IR reflecting layer located over at least said IR reflecting layer comprising Ag and/or Au. 14. A coated article including a glass substrate supporting a coating, wherein the coating comprises: at least one dielectric layer; an IR reflecting layer comprising Ag and/or Au provided on the substrate, the IR reflecting layer being located over at least the at least one dielectric layer; at least one additional layer provided on the substrate over at least the IR reflecting layer; wherein the IR reflecting layer at least one of: (a) comprises silver and has a majority compressive stress, and/or (b) has an argon and/or krypton content at an upper portion thereof which is greater than that at a lower portion thereof; and wherein an upper portion of the IR reflecting layer has an argon and/or krypton concentration at least 20% higher than that of a lower portion of the IR reflecting layer. 15. The coated article of claim 14, wherein the upper portion of the IR reflecting layer has an argon concentration at least 20% higher than that of the lower portion of the IR reflecting layer. 16. The coated article of claim 14, wherein the upper portion of the IR reflecting layer has a krypton concentration at least 20% higher than that of the lower portion of the IR reflecting layer. 17. The coated article of claim 14, further including another IR reflecting layer located over at least said IR reflecting layer comprising Ag andlor Au. 18. A coated article including a glass substrate supporting a coating, wherein the coating comprises: at least one dielectric layer; an IR reflecting layer comprising Ag and/or Au provided on the substrate, the IR reflecting layer being located over at least the at least one dielectric layer; at least one additional layer provided on the substrate over at least the IR reflecting layer; and wherein the IR reflecting layer comprises silver and has a majority compressive stress, and wherein the IR reflecting layer has an argon and/or krypton content at an upper portion thereof which is greater than at a lower portion thereof.
