Abstract: A method of inspecting a substrate includes irradiating light onto a substrate that has experienced a first process, obtaining spectral data of the light reflected from the substrate, detecting a defect region of the substrate from the spectral data, and extracting a first defect site that occurred in or during the first process from the defect region. Extracting the first defect site includes establishing an effective area where the first process affects the substrate, and extracting a superimposed area that is overlapped with the effective area from the defect region. The superimposed area is defined as the first defect site.

Abstract: A surface inspecting method includes: irradiating an incident light beam of a first polarized state on a target object, the incident light beam comprising parallel light and having a cross-sectional area: measuring a second polarized state of a reflected light beam reflected from the target object; and performing inspection on an entire area of the target object on which the incident light beam is irradiated, based on a variation between the first polarized state and the second polarized state.
