  • Thermal gradient control for enhanced laser induced crystallization of predefined semiconductor areas
    Patent number: 4330363
    Abstract: A method for laser induced conversion of large predefined areas of amorphous or polycrystalline semiconductor material, disposed nonepitaxially upon a substrate, into large single crystal areas, by controlling the lateral heat flow out of the melted regions of the areas for causing their recrystallization from a single nucleation site and for suppressing the formation of competitive nucleation sites at their edges.
