    摘要: A method for fabricating a radiation-emitting semiconductor chip having a thin-film element based on III–V nitride semiconductor material includes the steps of depositing a layer sequence of a thin-film element on an epitaxy substrate. The thin-film element is joined to a carrier, and the epitaxy substrate is removed from the thin-film element. The epitaxy substrate has a substrate body made from PolySiC or PolyGaN or from SiC, GaN or sapphire, which is joined to a grown-on layer by a bonding layer, and on which the layer sequence of the thin-film element is deposited by epitaxy.

    摘要: In the process for producing low-defect semiconductor layers based on III-V nitride semiconductor material, a substrate (1) made from a material which is not based on III-V nitride semiconductors is provided, and then a mask layer (2) is applied to the substrate in order to form unmasked regions (2c) and masked regions (2a, 2b) on the substrate. Then, starting from the unmasked regions (2c) of the substrate (1), the III-V nitride semiconductor layer (3) is grown. To avoid the formation of stress-induced cracks during the cooling phase from the growth temperature to room temperature, the mask layer (2) is formed on the substrate (1) in such a manner that some of the masked regions (2b) are wide enough to prevent the III-V nitride semiconductor layer (3) from growing together over these wide masked regions (2b), whereas the III-V nitride semiconductor layer does grow together only over the other, narrow masked regions (2a).
