A semiconductor light emitting device has a semiconductor laminate including first and second conductivity type semiconductor layers respectively providing first and second main surfaces and an active layer. The semiconductor laminate is divided into first and second regions. At least one contact hole is formed to pass through the active layer from the second main surface of the first region. A first electrode is formed on the second main surface to be connected to the first conductivity type semiconductor layer of the first region and the second conductivity type semiconductor layer of the second region. A second electrode is formed on the second main surface of the first region to be connected to the second conductivity type semiconductor layer of the first region and the first conductivity type semiconductor layer of the second region.

A method of growing a III group nitride single crystal by using a metal-organic chemical vapor deposition (MOCVD) process, the method including: preparing an r-plane (1-102) substrate; forming a nitride-based nucleation layer on the substrate; and growing a nonpolar a-plane nitride gallium single crystal on the nitride-based nucleation layer while altering increase and decrease of a ratio of V/III group to alternate a horizontal growth mode and a vertical growth mode.
