Patent ID: 7659557

Claim:
A semiconductor light-emitting device, comprising: a substrate; a first conductive type semiconductor material layer, formed on the substrate; a light-emitting layer, formed on the first conductive type semiconductor material layer such that a partial area of the first conductive type semiconductor material layer is exposed; a first electrode, formed on the exposed partial area of the first conductive type semiconductor material layer; a second conductive type semiconductor material layer, formed on the light-emitting layer; a II-IV-V group compound ohmic contact layer, formed on the second conductive type semiconductor material layer, wherein the material of the II-IV-V group compound ohmic contact layer is represented by the general formula: M x NyQ z , where M represents the II group chemical element, N represents the IV group chemical element, Q represents the V group chemical element, 1≦x≦3, 1≦y≦3, 1≦z≦3, and x and y and z are molar numbers; a transparent conductive layer, formed on the II-IV-V group compound ohmic contact layer such that a partial area of the II-IV-V group compound ohmic contact layer is exposed; and a second electrode, formed on the exposed partial area of the II-IV-V group compound ohmic contact layer and contacting the transparent conductive layer.
