Abstract
Glass substrates and methods for forming glass substrates are disclosed. The glass substrates include a planar A-side surface having a surface roughness Raof less than 0.5 nm and a planar B-side having a surface roughness Rawherein the ratio Ra:Rais greater than or equal to about 1.5. A plurality of texturing features are formed in the B-side surface. The plurality of texturing features have a peak-to-valley height H such that 0.05 μm≦H≦3.75 μm. The texturing features are distributed in the B-side surface such that a center-to-center pitch P between adjacent texturing features is at least 1.5 mm in at least one direction. The plurality of texturing features are formed in the B-side surface while the glass substrate is at a temperature T, wherein 600° C.≦T≦1200° C. and a viscosity of the glass substrate is from greater than 150,000 Poise and less than 10Poise.
