    Abstract: A method is provided for producing a nitride compound semiconductor device. A growth substrate has a silicon surface. A buffer layer, which comprises AlxInyGa1-x-yN with 0≦x≦1, 0≦y≦1 and x+y≦1, is grown on onto the silicon surface of the substrate. A semiconductor layer sequence is grown onto the buffer layer. The buffer layer includes a material composition that varies in such a way that a lateral lattice constant of the buffer layer increases stepwise or continuously in a first region and decreases stepwise or continuously in a second region, which follows the first region in the growth direction. At an interface with the semiconductor layer sequence, the buffer layer includes a smaller lateral lattice constant than a semiconductor layer of the semiconductor layer sequence adjoining the buffer layer.
