Abstract
In an embodiment a photodiode includes a semiconductor body having a light entrance side and a back side opposite the light entrance side, a first electrode at the light entrance side atop a first doped area of a first conductivity type, a second electrode at the light entrance side atop a second doped area of a second conductivity type, the second doped area being configured to absorb radiation, a gate region at the light entrance side at least between the first electrode and the second electrode, the gate region being connected to a gate electrode, a base electrode at the semiconductor body, the base electrode being configured to receive a current flow from the first electrode, the current flow being indicative of a radiant flux of the radiation onto the second doped area and a radiation shield covering and shielding the first doped area from the radiation to be detected.
