Abstract
The invention relates to a semiconductor device having a semiconductor substrate, on which a semiconductor layer is provided, which includes sunken or buried strip-shaped conducting regions, which have strip-shaped subregions, in which doping elements are present. Semiconductor devices having such so-called quasi unidimensional conductors constitute potentially important parts of electronic circuits or components. According to the invention, the strip-shaped conducting regions and the strip-shaped subregions are located with a side facing the substrate substantially in one plane, which is a vicinal plane of a major crystal surface of the semiconductor body, of which the semiconductor device forms part. The subregions can also have a very small width and thickness of about 0.3 to 2 nm and can be manufactured in a comparatively simple manner.
