    摘要: A sensor includes a semiconductor body having a top and bottom surface, a first doped surface oriented region of a first conductivity type at the top surface, and a second doped surface oriented region of a second and opposite conductivity type at the bottom surface, wherein a sensitive area is defined where the first region overlaps with the second region. A resistive layer is partially arranged in the sensitive area. The sensor includes two first electrode contacts and two second electrode contacts, wherein the first electrode contacts are placed on the resistive layer to define a first detection area in the sensitive area between the first electrode contacts, and wherein the second electrode contacts are placed partially in the sensitive area on the bottom surface of the body, the surfaces of the second electrodes in the sensitive area defining a second detection area that overlaps with the first detection area.
