  • Patent number: 10551326
    Abstract: A method for measuring a semiconductor device is provided. A method for measuring a semiconductor device includes defining an interest area and an acceptable area in a chip area on a wafer; performing a first measurement of the chip area with a spectral imaging device to acquire spectrum data of the chip area; assuming the distribution of the spectrum data of a first pixel in the acceptable area is a normal distribution; calculating a distance from a central point on the normal distribution to second pixels in the interest area; selecting a position of a second pixel having a distance from the central point on the normal distribution greater than a predetermined range, among the second pixels, as a candidate position; and performing a second measurement of the candidate position.
    Type: Grant

  • Patent number: 8753838
    Abstract: Provided is a method for producing alcohol or hydrogen gas comprising culturing alcohol-producing microorganisms in a waste fermented solution generated from the bioethanol production process. Glycerol included in the waste fermented solution generated from the bioethanol production process is converted by the microorganisms to butanol under an anaerobic condition. Since the waste fermented solution generated from the bioethanol production process can be utilized as a source of a biofuel, environmental and energy problems can be solved at once.
    Type: Grant
