    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: An epitaxial growth process for producing a thick III-N layer, wherein III denotes at least one element of group III of the periodic table of elements, is disclosed, wherein a thick III-N layer is deposited above a foreign substrate. The epitaxial growth process preferably is carried out by HVPE. The substrate can also be a template comprising the foreign substrate and at least one thin III-N intermediate layer. The surface quality is improved by providing a slight intentional misorientation of the substrate, and/or a reduction of the N/III ratio and/or the reactor pressure towards the end of the epitaxial growth process. Substrates and semiconductor devices with such improved III-N layers are also disclosed.
