Optoelectronic semiconductor component and method for producing an optoelectronic semiconductor component

An optoelectronic semiconductor device with a semiconductor layer sequence and with at least one electrical via, wherein

• the semiconductor layer sequence comprises an active zone for generating radiation and a contact layer for electrical contacting of the semiconductor layer sequence,
• the active zone lies in a plane (P) perpendicular to a main growth direction (G) of the semiconductor layer sequence and is located between a first semiconductor region with a first conductivity type and a second semiconductor region with a second conductivity type different from the first one
• the contact layer is located within the second semiconductor region,
• the via extends through the contact layer, and
• a contact region between the via and the contact layer includes a contact angle (w) to the plane (P) of at least 20° and of at most 70°.
