Abstract
A heat treatable coated article includes an anti-migration or barrier layer(s) provided between a solar management layer (e.g., NiCr layer) and a dielectric layer (e.g., silicon nitride). In certain example embodiments, the anti-migration or barrier layer(s) may include a metal oxide, and functions to prevent element(s) from migrating between the solar management layer and the dielectric layer upon heat treatment (HT) of the coated article. As a result, the coated article has improved color stability (and thus a lower &Dgr;E* value) upon HT. For example, the coated article may have a &Dgr;E* value (transmissive and/or glass side reflective) upon HT of no greater than 5.0, more preferably no greater than 4.0. Coated articles herein may be used in the context of insulating glass (IG) window units, other architectural windows, vehicle windows, or the like.
