Patent ID: 7943944

Claim:
A radiation-emitting semiconductor device comprising: a reflective layer or interface; and a multilayer structure comprising: an active, radiation-generating layer; a first main area coupled to the reflective layer or interface; and a second main area remote from the first main area for coupling out the radiation generated in the active, radiation-generating layer, wherein the multilayer structure is an epitaxial layer structure, the semiconductor device is free of a deposition substrate of the multilayer structure, a region of the multilayer structure that adjoins the second main area of the multilayer structure is patterned one- or two-dimensionally to form convex elevations, and a height (h 1 ) of the elevations is at least as large as a height (h 2 ) of an unpatterned region of the multilayer structure that is between the active, radiation-generating layer and the elevations.
