  • Patent number: 10481005
    Abstract: A semiconductor substrate measuring apparatus includes a light source unit generating irradiation light including light in a first wavelength band and light in a second wavelength band. An optical unit irradiates the irradiation light on a measurement object and condenses reflected light. A light splitting unit splits the reflected light, condensed in the optical unit, into a first optical path and a second optical path. A first detecting unit is disposed on the first optical path and detects first interference light in the first wavelength band in the reflected light. A second detecting unit is disposed on the second optical path and detects second interference light in the second wavelength band in the reflected light. A controlling unit calculates at least one of a surface shape or a thickness of the measurement object. The controlling unit calculates a temperature of the measurement object.
