  • Ring crystallization of wafers to prevent thermal shock
    Patent number: 5317186
    Abstract: A ring of polycrystalline material is developed around the edge of a wafer by general heating of the wafer and localized heating with a laser beam followed by rapid cooling. The ring of polycrystalline material helps prevent wafer breakage due to thermal shock. One or more additional ring, loop or closed figures of polycrystalline material can be formed inside of said ring of polycrystalline material developed around the edge of the wafer to further reinforce the wafer.
    Type: Grant
    Filed: June 15, 1992
    Date of Patent: May 31, 1994
