Abstract

An optoelectronic semiconductor component includes a substrate that has an upper side and an under side lying opposite the upper side. The substrate is formed with an electrically conductive mounting region, an electrically conductive connection region and an electrically isolating oxidation region. An optoelectronic part is arranged on the upper side of the substrate in the region of the mounting region. The oxidation region electrically isolates the mounting region from the connection region. The oxidation region extends, without interruption, from the upper side of the substrate to the underside of the substrate. The mounting region and the connection region are formed with aluminum and the oxidation region is formed with an oxide of the aluminum. The mounting region, the oxidation region and the connection region being are designed contiguously to form an entity.
