Abstract
Diode includes light emitting region, first metal layer, dielectric layer, and second metal layer. Light emitting diode includes n-type group III-nitride portion, p-type group III-nitride layer, and light emitting region sandwiched between n- and p-type layers. First metal layer may be coupled to p-type III-N portion and plurality of first terminals. First metal layer and p-type III-N portion may have substantially similar lateral size that is smaller than 200 micrometers. A portion of light emitting region and first metal layer may include a single via. Electrically-insulating layer may be coupled to first metal layer and sides of the single via. First terminals may be exposed from electrically-insulating layer. Second metal layer may include second terminal and may be coupled to electrically-insulating layer and to n-type III-N portion through the single via. The thickness of the diode excluding second terminal may be between 2 and 20 micrometers. Other embodiments are described.
