Patent ID: 6946687

Claim:
A radiation-emitting semiconductor chip, comprising: a substrate having a main surface area; and a series or layers disposed on said main surface area, at least one of said layers being a radiation-emitting active layer generating a radiation, said active layer being subdivided into subregions, each of said subregions having side faces disposed transverse to said active layer; at least one of said active layer and said series of layers being subdivided by recesses, said recesses having side faces, at least one of said recesses having a side face disposed at an angle other than 90° with respect to said main surface area of said substrate; said at least one of said recesses having at least some of said side faces and a bottom face, said side faces of said at least one of said recesses being separated from one another to cause at least a portion of radiation impinging on said bottom face to be reflected at said bottom face and subsequently be coupled out of at least one of said substrate and said series of layers.
