Claim:
1. A coated article comprising: a glass substrate; an infrared (IR) reflective layer comprising silver over at least the substrate, wherein the IR reflective layer comprising silver is located on and directly contacting a layer comprising zinc oxide; a contact layer located on and directly contacting the IR reflecting layer comprising silver; a dielectric layer formed over the IR reflective layer comprising silver and over the contact layer, so that the IR reflective layer is formed between at least the dielectric layer and the glass substrate, the dielectric layer comprising a zinc tin aluminum oxide, wherein an atomic ratio of zinc to tin in the dielectric layer is between about 0.67 and about 1.5, and wherein the dielectric layer comprises between about 1 atomic % and 15 atomic % aluminum; and a layer comprising silicon nitride located over at least the dielectric layer comprising zinc tin aluminum oxide.
