    摘要: The in vivo three component areal density composition of a patient along a transmitted x-ray beam is derived by raster-scanning a collimated x-ray beam across a bony region of the patient, with each point scanned at different energies, and using matrix equations with a priori spectra information to solve for the relative areal density of soft tissue, fat and bone.

    摘要: The present invention provides for characterization of a film (e.g., thickness determination for a silicon oxynitride film) using collected spectral data. For example, an acquired spectrum may be cumulatively integrated and the geometric properties of the integrated spectrum may be used to determine component concentration information. Thickness measurements for the film may be provided based on the component concentration information.

    摘要: The density of a mass of material is determined by passing radiation from a source, such as Co-60, whose radiation spectrum has a characteristic energy level above 700 keV through the mass of material to a detector that can detect radiation at a energy level, or range of energy levels, within the range 80 to 700 keV. By determining the density of the mass of material at different locations, the density profile of the mass of material can be assessed.

    摘要: This invention provides a measurement device that includes both an X-ray reflectometer and a thermal or plasma wave measurement module for determining the characteristics of a sample. Preferably, these two measurement modules are combined into a unitary apparatus and arranged to be able to take measurements at the same location on the wafer. A processor will receive data from both modules and combine that data to resolve ambiguities about the characteristics of the sample. The processor can be part of the device or separate therefrom as long as the measurement data is transferred to the processor.

    摘要: Non-invasive quantitative plain radiographic evaluation of bone in a bony locale of a body is performed by subjecting the bony locale to a broadband collimated x-ray beam having energy in the range of about 20 keV to 150 keV. Alongside the bony locale is a composite phantom. The composite phantom is comprised of at least two materials, superimposed on one another. An energy-selective multiple-film detector cassette containing at least two films is placed under the body and composite phantom to receive the transmitted x-ray beam. The films in the cassette are developed and digitally scanned to produce sets of composite phantom data and sets of bone data. The data sets are then numerically processed using interpolation whereby to generate the indicated estimate of bone status, namely, bone-mineral density. In an alternative embodiment, an independent measurement is made of the total tissue thickness, and the bone status is determined using interpolation based only on a single film.

    摘要: A film thickness measuring apparatus applies an electron beam to a thin film as a measurement object formed on a substrate, and measures a value of substrate current that flows in the substrate thereupon. The film thickness measuring apparatus corrects the substrate current value taking into account an influence of a charge distribution generated in the neighborhood of the thin film due to the application of the electron beam or an influence of a configuration of the surface of the substrate in the neighborhood of the thin film. The film thickness measuring apparatus acquires reference data representing a correlation between film thicknesses and substrate current values with respect to standard samples and calculates a thickness of the thin film from the corrected substrate current value taking into account the reference data.
