description Provided are a multilayer structure inspection apparatus and method of inspecting a multilayer structure in a sample without damaging the sample, the multilayer structure inspection apparatus being configured to measure both of reflectance and dispersion without damaging the sample, wherein the reflectance and dispersion are variables which are changed sensitively to a change in a repetitive pattern of the multilayer structure, by measuring values thereof, a structural change of the sample between before and after a process is inspected with high accuracy.
