Abstract:
1. A photodiode device comprising: an electrically conductive cathode layer on a photodiode layer made of a semiconductor material; doped anode regions on an upper side of the photodiode layer facing away from the cathode layer; a trench that subdivides the photodiode layer; a conductor layer that is arranged in or on the trench and that electrically connects the cathode layer with a cathode terminal arranged above the upper side of the photodiode layer; and anode terminals arranged above the upper side of the photodiode layer and electroconductively connected with the anode regions, wherein a plurality of mutually separated cathode terminals are provided, and the conductor layer does not fill the trench and has a plurality of mutually separated portions, each connected to one of the respective cathode terminals.
