Abstract:
A method for producing an optoelectronic component is disclosed. In an embodiment the method includes a metallization with first mask structures is deposited directionally, and then a first passivation material is deposited non-directionally onto the metallization. Further, cutouts are introduced into the semiconductor body, such that the cutouts extend right into an n-type semiconductor region, and a second passivation material is applied on side faces of the cutouts. Furthermore, an n-type contact material is applied, structured and passivated. Moreover, contact structures are arranged on the semiconductor body and electrically connected to the n-type contact material and the metallization, wherein the contact structures and the semiconductor body are covered with a potting.
