Claim:
1. A semiconductor device, comprising: a light emitting structure including first and second conductivity-type semiconductor layers including AlxInyGa(1−x−y)N, wherein 0≦x<1, 0≦y<1, and 0≦x+y<1, and an active layer between the first and second conductivity-type semiconductor layers; and an interconnection bump including: an under bump metallurgy (UBM) layer on an electrode of at least one of the first and second conductivity-type semiconductor layers, the UBM layer having a first surface opposite to a surface of the electrode and a second surface extending from an edge of the first surface and connecting to the electrode, wherein the second surface is a sloped sidewall of the UBM layer; an intermetallic compound (IMC) on the first surface of the UBM layer; a solder bump bonded to the UBM layer with the IMC therebetween; and a barrier layer on the second surface of the UBM layer and substantially preventing the solder bump from diffusing into the second surface of the UBM layer.
