Abstract:
1. An optoelectronic semiconductor body comprising: a front face provided for emission and/or reception of electromagnetic radiation, a rear face which lies opposite the front face and is provided for application onto a support plate, and an active semiconductor layer sequence which in a direction from the rear face to the front face comprises a layer of a first conductivity, an active layer and a layer of a second conductivity in this sequence, wherein the semiconductor layer sequence comprises at least one recess which extends from the rear face into the semiconductor layer sequence, wherein in a lateral direction parallel to a main extension direction of the semiconductor layer sequence the recess is completely surrounded by a continuous rail of the active layer; the recess comprises a first portion which extends through the layer of the first conductivity and the active layer into the layer of the second conductivity and comprises in the layer of the second conductivity a base surface which comprises points of the first portion which are most distant from the rear face; the recess comprises a second portion having an opening, wherein in the lateral direction the opening does not completely surround a region of the active layer, and wherein in a plan view of the rear face the opening is completely surrounded by an outer contour of the base surface of the first portion, and wherein the second portion extends starting from the opening in the direction towards the front face and extends at least in the layer of the second conductivity type.
