摘要: An apparatus includes an evaluating unit and a peak detection unit. The peak detection unit is configured to determine at least one peak parameter of a peak in a Fourier transformed reflection spectrum of infrared radiation reflected off a sample that may comprise trench structures. The evaluation unit is configured to determine from the at least one peak parameter and from a correction value containing information about an effective refractive index of the sample, a trench parameter of the trench structures.
