A phosphor coating process for a light-emitting device is described. A light-emitting diode chip is bonded on a substrate. A light-sensitive layer is formed over the light-emitting diode and the substrate. The light-sensitive layer is patterned by a photolithography process to expose an area of the light-emitting...http://www.google.fr/patents/US7919229?utm_source=gb-gplus-shareBrevet US7919229 - Phosphor coating process for light emitting diode
