The present invention provides a method of making a coated article,
including the steps of: (A) providing a substrate; (B) depositing one or
more dielectric layers over the substrate, the dielectric layers
comprising: (i) a first dielectric film having at least one film of zinc
oxide, silicon oxide, tin oxide, silicon nitride, silicon oxynitrate, or
an oxide of an alloy of zinc and tin having zinc in a weight percent
range of 10 to 90 and tin in a weight percent range of 90 to 10, and (ii)
a second dielectric film deposited over the first dielectric film, the
second dielectric film having at least: a zinc oxide, tin oxide film,
wherein the zinc oxide, tin oxide film has tin in a weight percent range
of greater than 0 to less than 10 and the majority of the balance being
zinc; and (C) depositing one or more infrared reflective layers on at
least one of the dielectric layers.
