Patent ID: 7294520

Claim:
A method for fabricating a plurality of semiconductor bodies, comprising: (a) forming a mask layer directly on a substrate comprising at least one material from the group consisting of silicon, silicon carbide and sapphire which mask layer has a plurality of windows leading to the substrate and onto which mask layer a semiconductor material, which is to be grown onto the substrate in a subsequent method step, substantially cannot be grown or can be grown to a significantly reduced extent by comparison with the substrate, (b) etching back the substrate in the windows, in such a manner that pits are formed in the substrate starting from these windows, (c) growing the semiconductor material onto the substrate, in such a manner that lateral growth is promoted and (i) the semiconductor material initially grows primarily from the flanks of the pits toward the center of the pits where the semiconductor material forms a coalescence region, so that defects in the substrate which impinge on the flanks of the pits bend off toward the center of the pits in the semiconductor material, and then (ii) the semiconductor material, starting from the windows, grows over the mask layer and in each case grows together over the mask layer between adjacent windows, where the semiconductor material forms a further coalescence region, and (d) growing a component layer sequence onto the semiconductor material.
