Zusammenfassung:A semiconductor test structure is provided for detecting raised source/drain regions-gate electrode shorts, including a semiconductor substrate, FETs formed on the semiconductor substrate, raised source/drain regions of the FETs formed on the semiconductor substrate, a gate electrode structure comprising multiple gate electrodes of the FETs arranged in parallel to each other, and a first electrical terminal electrically connected to the gate electrode structure, and wherein no electrical contacts to the raised source/drain regions are present between the multiple gate electrodes of the gate electrode structure.
