  • Patent number: 9400172
    Abstract: A measurement target including a semiconductor substrate, and a first epitaxial layer and a second epitaxial layer stacked in this order on the semiconductor substrate and having no difference in refractive index of a real part from the semiconductor substrate is subjected to reflection interference analysis using a Fourier transform infrared spectroscopy. The thickness of the first epitaxial layer is used as a fitting parameter so as to prevent shift between an interference waveform of a resultant reflection interference pattern containing distortion appearing in a wave number range near an abnormal dispersion range of a refractive index caused by phonon absorption and an interference waveform of a numerically calculated reflection interference pattern in the same wave number range. The thickness of the first epitaxial layer determined during the fitting of the numerically calculated reflection interference pattern is defined as a measured value of the thickness of the first epitaxial layer.

  • Patent number: 9267895
    Abstract: Provided is a chemical analysis device to analyze a chemical composition of a sample, including a main body including a laser light source, a chemical analysis unit, and a housing; an optical head that is arranged to be faced to the sample; and a pressureproof-feedthrough-equipped fiber that is extended from the housing to the optical head to guide laser light emitted from the laser light source to the optical head. The housing houses the laser light source and the chemical analysis unit as having a pressure-resistant function. The optical head includes a mirror system that causes the sample to be irradiated with laser light outgoing from the pressureproof-feedthrough-equipped fiber and to cause plasma emission light occurring at the sample owing to irradiation with the laser light to reenter to the pressureproof-feedthrough-equipped fiber. The chemical analysis unit performs spectroscopic analysis on the plasma emission light that reentered to the pressureproof-feedthrough-equipped fiber.
