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.
