Abstract
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 diode chip, on which desires a phosphor coating. A phosphor-adhesive material is filled on the area of the light-emitting diode chip.
