  • Method for identifying desired features in a crystal
    Patent number: 6055293
    Abstract: A method for identifying desired features in an off-orientation crystal uses radiation, such as x-rays, directed toward the crystal in a first direction to detect a unique region in a first direction. Based on identifying the unique region, the location of a desired feature, such as a key growth line, is approximated. Radiation is then directed at the crystal in a second direction transverse to the first direction to determine the precise location of the desired feature. The method can be performed automatically by a programmed x-ray device.
