SEM (scanning electron microscopy)-based nanoprobing technique [1] is frequently used to identify the soft failure and non visible defects. This technique provides the capability of operating probe tips in nanometer range to land exactly on top of the individual source, drain and gate tungsten contact, for instance, as shown in Figure 2825. The SEM provides a high-resolution real-time image that facilitates locating the failing device and placing the probe tips. In this way, the locations of soft failure and non visible defects can become visible during electrical stressing.
