Abstract

The striation spacing in spin on glass (SOG) coatings was discussed taking into consideration the effect of radial position and spin speed. SOG on silicon solutions were used for layering planar optical waveguides and planar lightwave circuits (PLC). The striation occurence was directly linked to solvent evaporation during spin coating. It was found that composition-gradient-driven capillary effects, collectively known as the Marangoni effect, could be instigated by solvent evaporation during spin coating.
