  • Publication number: 20240151665
    Abstract: Provided is an inspection system capable of estimating electric characteristics of a sample with high accuracy regardless of an initial charging state of a wafer. The inspection system includes a charged particle beam device and a computer system, and inspects the electric characteristics of the sample. The inspection system evaluates initial charging of an inspection region including inspection patterns based on reference data indicating a secondary charged particle signal from a reference pattern corresponding to a plurality of pulse conditions. The reference pattern has the same electric characteristics as the inspection pattern and initial charging therein caused by electric charges that are not emitted according to a discharge time constant of the sample is negligible. The reference pattern is obtained by irradiating the reference pattern with a pulse charged particle beam under a plurality of pulse conditions.
