Abstract
An optoelectronic semiconductor device includes a semiconductor body having a semiconductor region and an active region, wherein the semiconductor region has a covering layer forming a radiation passage surface of the semiconductor body on a side facing away from the active region, the semiconductor region has a current-spreading layer arranged between the covering layer and the active region; the semiconductor device has a contact for the electrical contacting of the semiconductor region; the contact adjoins the current-spreading layer in a terminal area; the contact adjoins the covering layer in a barrier region; and the barrier region runs parallel to the active region and is arranged closer to the active region than the radiation passage surface.
