    Abstract: Consistent with an example embodiment, there is a semiconductor device with nanowire-type interconnect elements.The semiconductor device comprises a semiconductor substrate with a pn junction formed by a first doped substrate region of a first conductivity type, and a second doped substrate region of an opposite second conductivity type. There is a layer structure on the semiconductor substrate, the layer structure includes a first metal structure which is conductively connected with the first doped substrate region, and further comprising a second metal structure, which is conductively connected with the second doped substrate region. The layer structure allows the transmission of photons with an energy suitable for creating free charge carriers in the first and second doped substrate regions. A third metal structure comprising at least one self-assembled metal dendrite forms an interconnect element between the first and second metal structures.
