Claim Text:
1. A method of making a semiconductor light emitting device, comprising: positioning a stencil on a substrate such that a semiconductor light emitting element disposed on the substrate is positioned within an opening in the stencil; depositing a phosphor-containing material in the opening to form a coating on a light emitting surface of the semiconductor light emitting element, wherein the light emitting surface emits light having a first dominant wavelength upon the application of a voltage to the semiconductor light emitting element, and wherein phosphor particles in the phosphor-containing material convert light emitted by the light emitting surface to light having a second dominant wavelength different from the first dominant wavelength; measuring light conversion by the phosphor-containing material as the phosphor-containing material is being deposited in the stencil opening; causing phosphor particles in the material to become arranged in a densely packed layer within the material at the light emitting surface, when the amount of phosphor-containing material is sufficient to convert light to a desired color point; and curing the material without disturbing the densely packed layer of phosphor particles.
