Patent ID: 7541621

Claim:
A semiconductor light emitting device comprising: a first conductivity-type first semiconductor layer; an emission layer; a second conductivity-type second semiconductor layer; a second conductivity-type transparent substrate transparent to light beams from the emission layer and directly bonded to the second semiconductor layer which are formed in this order; a first electrode to which a probe is connectable on a surface of the first semiconductor layer opposite to the emission layer, wherein said first electrode is in non-ohmic contact with the first semiconductor layer; and a second electrode which is positioned around the first electrode on a surface of the first semiconductor layer, and which is electrically connected to the first electrode and is in ohmic contact with the first semiconductor layer; and a current narrowing portion formed on the transparent substrate bounding on the second semiconductor layer; wherein the transparent substrate has a parallel surface almost parallel to the emission layer on an opposite side of the emission layer, and an inclined surface adjoining the parallel surface and inclined to the parallel surface and the current narrowing portion defines a light emitting region in the emission layer at a position almost identical to the first electrode in plan view.
