Zusammenfassung:A device includes a detector, a sensing pad, a ring structure, a control circuit, a first transistor, and a second transistor. The sensing pad is electrically connected to the detector. The ring structure is over the sensing pad and includes an upper conductive ring and a lower conductive ring between the upper conductive ring and the sensing pad. The first transistor interconnects the upper conductive ring and the control circuit. The second transistor interconnects the lower conductive ring and the control circuit.
