SEMICONDUCTOR LIGHT EMITTING DEVICE INCLUDING METAL REFLECTING LAYER

摘要

PURPOSE: A semiconductor light emitting device is provided to prevent the deterioration of a metal reflection layer by interposing a barrier layer between a light transmissive conductive layer and the metal reflection layer. CONSTITUTION: A semiconductor structure(11) includes an active region(8). A light transmissive conductive layer(13) is formed on the upper side of the semiconductor structure. A dielectric layer(4) is formed on the upper side of the light transmissive conductive layer. A metal reflection layer(22) is formed on the upper side of the dielectric layer. The dielectric layer has one or more opening parts(21) to partially expose the light transmissive conductive layer. The light transmissive conductive layer is electrically connected to the metal reflection layer by interposing the opening part. A barrier layer(24) is interposed between the light transmissive conductive layer and the metal reflection layer.
