Abstract:
1. A method for depositing coatings onto substrates, the method comprising: a) providing a coater having a substrate transport system defining a path of substrate travel extending through the coater, wherein at least part of one or more lower sputtering target(s) are mounted below the path of substrate travel; b) positioning a glass sheet on the transport system and conveying the glass sheet along the path of substrate travel, such that the glass sheet is conveyed over the one or more lower target(s); and c) sputtering the one or more lower target(s) so as to deposit a coating upon a bottom major surface of the glass sheet, wherein the bottom major surface of the glass sheet once coated contacts at least one surface of the transport system, the coating comprising a desired film having a refractive index of between about 1.57 and about 1.8, wherein the desired film forms part or all of the coating on said bottom major surface, the coating having a total optical thickness of less than about 400 angstroms.
