Abstract: A semiconductor measurement apparatus includes an illumination unit configured to provide illumination light including linearly polarized light beams having different wavelengths, an optical unit including an objective lens configured to allow the illumination light to be incident on a sample, the optical unit being configured to transmit reflection light generated when the illumination light is reflected from the sample, a self-interference generator configured to self-interfere the reflection light transmitted from the optical unit and transmit the reflection light to a first image sensor, for each wavelength, and a controller. The controller is configured to process a measurement image output by the image sensor to divide the measurement image into a first image representing an intensity ratio of a polarization component of the reflection light and a second image representing a phase difference of the polarization component of the reflection light, for each wavelength.

Abstract: An optical measurement system includes a hemispherical mirror including a planar portion and a spherical portion having a hemispherical recessed shape in the planar portion. In the spherical portion are latitude markers formed with a different reflectance from the rest of the spherical portion. The system includes an optical unit with an objective lens and at least one beam splitter. The optical unit transmits light reflected from the hemispherical mirror through the objective lens to a first sensor. A controller measures a numerical aperture of the objective lens by aligning the hemispherical mirror to be at the focus of the objective lens, detecting a back focal image of the objective lens in which the latitude markers appear as darker circular lines, and performing calculations on the image.
