OPTICAL SENSOR DEVICE AND METHOD FOR MANUFACTURING AN OPTICAL SENSOR DEVICE

An optical sensor device comprises a semiconductor body (10) with a light-sensitive area (11), metal layers (20) which are arranged above the light-sensitive area (11) and comprise an upper metal layer (21) and a lower metal layer (22), wherein the upper metal layer (21) is located at a greater distance from the light-sensitive area (11) than the lower metal layer (22). The optical sensor device further comprises an aperture opening (24) in the metal layers (20) above the light-sensitive area (11) and a via structure (30), which is arranged outside the aperture opening (24) and interconnects the metal layers (20) and/or the semiconductor body (10). The via structure (30) is arranged in such a fashion that any straight line (S) that is parallel to the light-sensitive area (11) and traverses the aperture opening (24) between the light-sensitive area (11) and the upper metal layer (21) is limited in both of its opposite directions by the via structure (30).
