  • Method for producing a semiconductor component
    Publication number: 20060246687
    Abstract: A method for producing a semiconductor component, in which a semiconductor layer (2) is separated from a substrate (1) by irradiation with laser pulses (6), the pulse duration of the laser pulses (6) being less than or equal to 10 ns. The laser pulses (6) have a spatial beam profile (7) with a flank slope chosen to be gentle enough to prevent cracks in the semiconductor layer (2) that arise as a result of thermally induced lateral stresses, during the separation of semiconductor layer (2) and substrate (1).
