Abstract
A method for producing a semiconductor component, in particular a thin-film component, a semiconductor layer being separated from a substrate by irradiation with a laser beam having a plateaulike spatial beam profile. Furthermore, the semiconductor layer, prior to separation, is applied to a carrier with an adapted thermal expansion coefficient. The method is suitable in particular for semiconductor layers containing a nitride compound semiconductor.
