Claim:
1. A charged particle beam apparatus comprising: a charged particle beam source; a control parameter setting portion of a Scanning Electron Microscope (SEM) control system configured to set irradiation energy of a charged particle beam emitted from the charged particle source; a master clock generator configured to provide a time base for a control signal; a deflection signal controller configured to apply the charged particle beam to a sample in synchronization with the time base and to control an irradiation position; a detection controller configured to detect an emission electron from the sample received by a detector in synchronization with the time base; a detection signal processor configure to analyze emission characteristics of the emission electron from a detection signal of the emission electron; and an analysis and display portion of the SEM control system configured to analyze electrical characteristics or cross-sectional morphological characteristics of the sample based on the emission characteristics of the emission electron.
