Abstract: A method of manufacturing a semiconductor light emitting device, includes forming a conductive film on a surface of a semiconductor light emitting element. Phosphor particles are charged by mixing phosphor particles with an electrolyte having a metallic salt dissolved therein. The semiconductor light emitting element having the conductive film formed thereon is immersed in the electrolyte having the charged phosphor particles. A phosphor layer on the conductive film is formed by electrophoresing the phosphor particles. The conductive film is removed using wet etching.

Abstract: A light emitting device package, comprises a light emitting structure having first and second electrodes insulated from each other; and a support structure. The support structure comprises: a first support electrode electrically connected to the first electrode of the light emitting structure; a second support electrode electrically connected to the second electrode of the light emitting structure, the second support electrode spaced apart from, and electrically insulated from, the first support electrode; and a support connection portion between the first support electrode and the second support electrode. The light emitting structure includes a protrusion portion that protrudes in a horizontal direction beyond a sidewall of at least one of the first support electrode and the second support electrode so that a void is present below the protrusion portion and above a plane extending from bottoms of the first and second support electrodes.
