Abstract
A polymer dispersion layer is formed on a substrate or semiconductor light-emitting devices on the substrate. After forming the polymer dispersion layer, drying and curing the polymer dispersion layer forms a cured polymer layer. After curing and drying, with the cured polymer layer being present on only selected, masked areas of the substrate or light-emitting devices, and with other areas of the substrate or light-emitting devices lacking the cured polymer layer and remaining exposed, a material layer is formed on at least the exposed areas of the substrate or light-emitting devices. After forming the material layer, the cured polymer layer is removed from the masked areas, leaving the material layer on the exposed areas.
