  • Patent number: 10890539
    Abstract: A semiconductor defect inspection apparatus for inspecting a specimen including a semiconductor substrate having a surface on which a predetermined pattern is formed, includes an excitation light irradiator, a polarization converter, a detector, and a defect analysis detector. The excitation light irradiator irradiates the specimen with excitation light along an optical path from the irradiator to the specimen and such that the excitation light is obliquely incident at a predetermined incident angle. The first polarization converter is disposed in the optical path, and converts the excitation light into s-polarized light. The detector detects photoluminescence light generated from the specimen when the excitation light is incident on the specimen. The defect analysis detector detects a dislocation defect by analyzing a photoluminescence image obtained by photoelectrically converting the photoluminescence light.
