摘要: In order to achieve an as uniform as possible temperature over the entire surface of the substrate (2) during a temperature step and, in particular, during an epitaxy method, temperature equalization structures are incorporated in a substrate holder (1), on which the substrate (2) is located. A uniform temperature distribution on the substrate surface during the deposition of a semiconductor material reduces the emission wavelength gradient of the deposited semiconductor material. The temperature equalization structures produce specific temperature inhomogenelties in the substrate holder (1), and these smooth out the temperature profile of the substrate (2). For example, a groove (4) with a cooling effect and a support step (5) which produces a gap (8) between the substrate (2) and the substrate holder (1) are integrated in the edge area of the substrate holder (1).

摘要: The deposition of material (3) on a growth area (4) may be highly temperature-sensitive. In order to reduce temperature inhomogeneities on the growth area (4) of a substrate wafer (1), a thermal radiation absorption layer (2) is applied on a rear side (5) of the substrate wafer (1) lying opposite to the growth area (4). The thermal radiation absorption layer (2) exhibits good radiation absorption in the spectral range of a heating source. Since the deposition of semiconductor materials, in particular AllnGaN, may lead to (depending on the deposition temperature) different emission wavelengths of the deposited material, the use of a thermal radiation absorption layer (2) may produce a narrower emission wavelength distribution of the deposited material (3).

摘要: A method for producing an optoelectronic component is provided. A transfer layer, containing InxGa1-xN with 0 x, is grown onto the previously grown transfer layer, ions are implanted into the further transfer layer to form a separation zone, a further carrier substrate is applied, and the further transfer layer is separated by way of heat treatment. Subsequently, a semiconductor layer sequence, containing an active layer, is grown onto the surface of the further transfer layer facing away from the further carrier substrate.
