Patent ID: 8124991

Claim:
A light emitting device, comprising: a III-nitride light emitting diode (LED) structure comprised of a III-nitride active layer positioned between at least a III-nitride p-type layer and at least a III-nitride n-type layer, wherein at least a portion of an N-face surface of the n-type layer is roughened to increase scattering and extraction of light, emitted by the LED structure, out of an n-type side of the light emitting device, as compared to an LED structure without an N-face surface of an n-type layer that is roughened; a p-type electrode deposited on or above the p-type layer, wherein the p-type electrode is transparent to the light emitted by the LED structure; and a transparent submount material attached to a surface of the p-type electrode to increase the light's extraction at the surface of the p-type electrode, wherein: (1) the transparent submount material is transparent to the light emitted by the LED structure, reduces reflections of the light occurring inside the LED structure, and increases extraction of the light from a p-type side of the light emitting device, as compared to a light emitting device without a transparent submount material, and (2) the p-type side is on an opposite side of the light emitting device from the n-type side.
