Abstract
A semiconductor wafer, a benchmark device embedded on a semiconductor wafer, and a method of operating a benchmark device embedded on a semiconductor wafer are provided. The semiconductor wafer includes a benchmark device disposed within a scribe line of the semiconductor wafer. The benchmark device includes a transistor, a diode, and a disconnecting switch electrically connected to the transistor and the diode. The disconnecting switch is configured to form a conductive path between the transistor and the diode at a first stage, and to electrically isolate the transistor from the diode at a second stage.
