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.

According to at least one embodiment of the optoelectronic component, the optoelectronic component includes a recess in the first region of the semiconductor body. This recess is transverse to the main extension plane of the semiconductor body. The main extension plane is transverse, in particular perpendicular, to the growth direction and/or to the stacking direction of the semiconductor body. Thus, the recess extends substantially along, such as parallel to, the growth direction and/or the stacking direction of the semiconductor body. The recess can have the shape of a trench, a cylinder or a truncated cone, for example. The cylinder axis or the truncated cone axis is arranged orthogonal to the main extension plane of the semiconductor body.

According to at least one embodiment of the optoelectronic component, the optoelectronic component includes a contact region adjacent to the recess. This contact region is used for electrical contacting of the semiconductor body.

According to at least one embodiment of the optoelectronic component, the optoelectronic component includes a semiconductor body with a first radiation exit surface. This first radiation exit surface is arranged on a main surface of the second region of the semiconductor body facing away from the active region. The first radiation exit surface is arranged such that at least part of the electromagnetic radiation generated during operation leaves the semiconductor body through the first radiation exit surface.
