To obtain data pertaining to the surface characteristics of a sample, a control method adjusts a tilted rastered E-beam to in SEM to a first/next tilt condition and navigates the SEM-beam to a sample site. The system performs a fine alignment step. Then the system scans a region of a sample to acquire a waveform. The system analyzes the waveform to determine the DESL value for each edge of interest. The system tests whether there is sufficient information available for each structural edge. If NO, the system repeats the above steps starting by changing the value of the tilt angle to acquire another waveform. If YES, the system determines the height and sidewall angles for each structural edge. Then the system reports the sidewall angle and the structure height for each edge of the structure under test. The system then corrects the critical dimension measurement determined from 0 degrees tilt scanning.
