Patent ID: 7768027

Claim:
A semiconductor light-emitting device, comprising: a substrate; a first conductive type semiconductor material layer, the first conductive type semiconductor material layer being formed on the substrate and having an upper surface, and the upper surface comprising a first region and a second region distinct from the first region; a first electrode being formed on the first region; a light-emitting layer being formed on the second region; a second conductive type semiconductor material layer being formed on the light-emitting layer; a second electrode being formed on the second conductive type semiconductor material layer; and a plurality of bump structures being formed on the upper surface of the first conductive type semiconductor material layer and between the first region and the second region, wherein the plurality of bump structures are in direct contact with the upper surface of the first conductive type semiconductor material layer, each of the plurality of bump structures is made of a material whose refractive index is larger than 1, and the material is one selected from the group consisting of ITO, SiO 2 , SiN, ZnO, polymide, BCB, SOG, InO, SnO, a Group III-V compound semiconductor material, and a Group II-VI compound semiconductor material.
