Abstract: 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.

Abstract: A radiation-emitting semiconductor chip may include a semiconductor body, a reflector, at least one cavity, and a seal. The semiconductor body may include an active region configured to generate electronic radiation. The reflector may be configured to reflect a portion of the electromagnetic radiation. The cavity may be filled with a material having a refractive index not exceeding 1.1. The seal may be impermeable to the material. The cavity may be arranged between the reflector and the semiconductor body, and the seal may cover the underside of the reflector.
