Various techniques can be used to analyze the dopants in semiconductors:
         i) Scanning electron microscopy (SEM) [1, 2],
         ii) Scanning spreading resistance microscopy (SSRM) [3],
         iii) Scanning capacitance microscopy (SCM) [4],
         iv) Off-axis electron holography [5],
         v) Secondary ion mass spectrometry (SIMS).

Except SIMS, the other techniques are applicable for the nanoscale dimensions of state-of-the-art semiconductor devices. Furthermore, one key to the success of dopant analysis in nanometer-scale is the specimen preparation to expose the region of interest, for instance, using focused ion beam (FIB) milling.
