  • Method of and apparatus for measuring energy gap of semiconductor
    Patent number: 5406505
    Abstract: A method and apparatus is disclosed for measuring an energy gap of a semiconductor material. The method contains the steps of analyzing a character of a reference semiconductor sample and setting an energy gap pixel value, estimating a transfer function between the pixel value, positioning the sample properly and imaging the spectrum to obtain a live image, storing the live image and scanning the respective pixel values along an x-axis of the image, sequentially comparing the respective pixel value and the energy gap pixel value, reading an x-coordinate of the pixel and converting the wavelength of the pixel to estimate the energy gap.
