Abstract

An optoelectronic semiconductor component may include at least one optoelectronic semiconductor chip, a reflector, a lens, and a connecting layer. The reflector may have a reflector recess where the semiconductor chip may be arranged. The lens may be fully located in the reflector recess, and the lens may have a lens recess. The connecting layer may fasten the lens on the reflector. The lens may have a lens outer side facing toward a reflector inner wall of the reflector recess. A gap may be between the reflector and the lens, and the gap may be filled only partially with the connecting layer. The semiconductor chip may not touch the lens. The optoelectronic semiconductor component may be incorporated into a biometric sensor.
