Patent ID: 6853204

Claim:
A semiconductor defect inspection device, comprising: deciding means for deciding irradiation conditions of a charged particle beam which include an electric current value of the charged particle beam; scanning means for scanning a specific area on a to-be-inspected object with the charged particle beam; measuring means for measuring an electron count and an energy level of at least one of secondary electrons and back scattering electrons emitted from the specific area; calculation means for calculating a charged voltage of the specific area based upon the energy level, and for calculating a corresponding electric resistance value based upon the electron count and the electric current value of the charged particle beam; and comparing means for comparing a charged voltage vs. electric resistance characteristic pattern of the to-be-tested object being composed of the changed voltage and the corresponding electric resistance value with the charged voltage vs. electric resistance characteristic pattern of said type of defect to determine whether said type of defect exists in the specific area.
