Abstract: A heat treatable coated article (e.g., vehicle windshield, IG unit, etc.) is provided with a dual-silver low-E coating. Before and/or after heat treatment (HT), the coating and/or coated article has a visible transmittance of at least 70%, more preferably at least 75%. Moreover, the coating and/or coated article is designed so as to have approximately the same color when viewed over a wide range of viewing angles. In certain embodiments, at least one contact layer (e.g., of or including NiCrOx) that contacts an infrared (IR) reflecting layer (e.g., Ag) is oxidation graded so that it progressively becomes less oxidized through its thickness as it nears the IR reflecting layer. In still other embodiments, a Si-rich silicon nitride layer(s) may be utilized to reduce haze.

Abstract: A sputter coating apparatus includes at least a first sputter coating line and a second sputter coating line. The first and second sputter coating lines may be operated in parallel with one another in certain embodiments in order to independently form coating systems and respective coated articles. However, the two coating lines may also be utilized so as to operate in series with one another to form a coated article. In the latter case, a transition zone is provided between an end of the first line and an end of the second line so as to selectively couple an output of the first line to an input of the second line when it is desired to utilize the two sputter coating lines in series with one another. In such a manner, it is possible to avoid many of the inefficiencies associated with conventional sputter coating apparatuses and processes.
