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 during at least part of forming an infrared (IR) reflecting layer(s) of such a coated article. Advantageously, this has been found to improve sheet resistance (Rs) properties, solar control properties, and/or durability of the coated article. Other layers may also be ion beam treated in certain example embodiments.
