摘要

An optoelectronic component may include a semiconductor body and a radiation transmissive bonding layer. The semiconductor body may include a first region of a first conductivity type, a second region of a second conductivity type, and an active region. The active region may be disposed between the first region and the second region. The first region may include a recess and a contact region adjacent to the recess. The active region may be arranged to emit electromagnetic radiation. The semiconductor body may have a first radiation exit surface at a main surface of the second region remote from the active region, and a portion of the electromagnetic radiation may exit the semiconductor body through the first radiation exit surface. The semiconductor body may include a first electrical connection layer and a second electrical connection layer where the second electrical connection layer is arranged at least partially in the recess.

FIG. 4A shows a method step for manufacturing an optoelectronic component 1 according to a fourth exemplary embodiment. The preceding method steps of the fourth exemplary embodiment correspond to the method steps of the third exemplary embodiment shown in FIGS. 3A to 3D. In the fifth method step shown in FIG. 4A according to the fourth exemplary embodiment, the growth substrate 150 is detached from the semiconductor body 10 and thus a second radiation exit surface 10B is produced on the side of the first region 101 facing away from the active region 103. Then a recess 160 is introduced in the first region 101. A radiation transmissive dielectric 132 is applied to the second radiation exit surface 10B.

FIG. 4B shows a method step for manufacturing an optoelectronic component 1 according to the fourth exemplary embodiment, in which a first electrical connection layer 121 is applied to the second radiation exit surface 10B for making electrical contact with the first region 101 of the semiconductor body 10. A second electrical connection layer 122 for electrically contacting the second region 102 of the semiconductor body 10 is arranged at least partially in the recess 160. To establish the electrical contact, a contact region 170 is formed at the interface of the second electrical connection layer 122 and the second region 102 of the semiconductor body 10 by means of a high-temperature process step.
