The present invention relates to a nucleic acid molecule or molecules and to a process for the detection of bacteria of the Salmonella genus. A momentary interruption detecting circuit detects a change in an output voltage when the output voltage suffers a momentary interruption over a short period of time. The sensor circuit can comprises a single or a plurality of, via chain including a plurality of vias connected in series, or wire monitor circuit extending in a serpentine conductive path through a plurality of wiring levels and vias, or interconnect, and the system can monitor the resistance or leakage or ratio of parameters of the sensor circuit. Each of the plurality of thin film transistors comprise a crystallized semiconductor layer, a gate insulating film adjacent to the crystallized semiconductor layer and a gate electrode adjacent to the gate insulating film.
