Abstract:
1. A semiconductor light emitting device comprising: a light emitting structure, the light emitting structure including a first conductivity-type semiconductor layer, an active layer on the first conductivity-type semiconductor layer, and a second conductivity-type semiconductor layer on the active layer; a first insulating layer on the light emitting structure, the first insulating layer defining a plurality of first openings, a first one of the plurality of first openings exposing the first conductivity-type semiconductor layer and a second one of the plurality of first openings exposing the second conductivity-type semiconductor layer; a barrier metal layer on the first insulating layer, the barrier metal layer being electrically connected to the first conductivity-type semiconductor layer and the second conductivity-type semiconductor layer through the first one and the second one of the plurality of first openings; a second insulating layer on the barrier metal layer, the second insulating layer defining a second opening that partially exposes the barrier metal layer; and an electrode on the barrier metal layer, the electrode being electrically connected to the first conductivity-type semiconductor layer and the second conductivity-type semiconductor layer through the barrier metal layer and the second opening, and at least one of the first and second insulating layers and the barrier metal layer are between the electrode and the light emitting structure.
