Inventor: AN IL SIN
IPC: G01N21/21
Filed: 2019-04-17
Abstract: The present invention relates to an ellipsometer, which may comprise: a reference sample mounting table on which a reference sample is mounted; a light source unit placed on one end of the reference sample mounting table for generating linear-polarized light and making the light incident into the reference sample; a measurement sample mounting table whose one end is engaged with the other end of the reference sample mounting table and on which the reference sample is mounted; and an optical image unit placed on the other end of the measurement sample mounting table for acquiring an image of the light reflected in the measurement sample. According to the present invention, the ellipsometer is capable of performing a measurement of one time without rotating an optical part such as a polarized light generator and a polarized light analyzer, thereby significantly reducing the measuring time. In addition, since the polarized light generator and polarized light analyzer are fixated at right angles, and the reference sample is always fixated and mounted, so an error in an alignment of optical parts and samples can be reduced. In addition, the reference sample and measurement sample are mounted together and compared and measured, so a difference of an equipment status in accordance with the difference in the point of time for measurement and operation generated due to a difference between users of the equipment can be reduced. In addition, the ellipsometer is capable of checking an outputted brightness image without needing to calculate {Δ, Ψ}, thereby immediately recognizing the presence or absence of a defect and the position of such defect in the measurement sample. In addition, the ellipsometer includes a composition of a rotatory polarization ellipsometer, so it can be used for identifying a defect and analyzing the cause of the defect through a rotation of the polarized light generator.
