Abstract:
1. Method of manufacturing a semiconductor device comprising a field effect transistor, in which method a semiconductor body of silicon with a substrate is provided at a surface thereof with a source region and a drain region of a first conductivity type which are situated above a buried isolation region and with a channel region, between the source and drain regions, of a second conductivity type, opposite to the first conductivity type, and with a gate region separated from the surface of the semiconductor body by a gate dielectric and situated above the channel region, and wherein a mesa is formed in the semiconductor body in which the channel region is formed and wherein the source and drain regions are formed on both side faces of the mesa with at least a predominate portion of the source and drain regions in a semiconductor region that is formed using epitaxial growth, the source and drain regions thereby contacting the channel and formed at least predominantly in material epitaxially grown, characterized in that the semiconductor region is formed contacting the mesa over substantially the whole thickness of the semiconductor region and is formed below the level of the gate dielectric.
