A light-emitting device comprises a light-emitting stack; a reflective structure comprising a reflective layer on the light-emitting stack and a first insulating layer covering the reflective layer; and a first conductive layer on the reflective structure; wherein the first insulating layer isolates the reflective layer from the first conductive layer.

Light-emitting element having a reflective structure with high efficiency

An optoelectronic element comprises a semiconductor stack comprising an active layer, wherein the semiconductor stack has a first surface and a second surface opposite to the first surface; a first transparent layer on the second surface; a plurality of cavities in the first transparent layer; and a layer on the first transparent layer, wherein the first transparent layer comprises oxide or diamond-like carbon.

A light-emitting element includes a reflective layer; a first transparent layer on the reflective layer; a light-emitting stack having an active layer on the first transparent layer; and a cavity formed in the first transparent layer.

A method of fabricating an optoelectronic device, comprising: providing a first substrate; forming an epitaxial stack on the first substrate wherein the epitaxial stack comprising a first conductive-type semiconductor layer, an active layer and a second conductive-type semiconductor layer; etching an upper surface of the second conductive-type semiconductor layer and forming a first texture profile on the upper surface of the second conductive-type semiconductor layer; forming a passivation layer on the upper surface of the second conductive-type semiconductor layer; and etching an upper surface of the passivation layer forming a second texture profile on the upper surface of the passivation layer wherein the first texture profile is different from the second texture profile.
