Abstract
A body region () with a first type of electric conductivity is arranged at the upper surface () of a substrate () in a well (), wherein a portion of the well that is not occupied by the body region has a second type of conductivity opposite the first type of conductivity. At the upper surface, a source region is arranged in the body region and a drain region is arranged in the well at a distance from the body region; the source region and the drain region both have the second type of conductivity. The body region is arranged underneath a surface area of the upper surface that has a border () with opposing first border sides (). The well has a varying depth in the substrate. The depth of the well is smaller underneath the first border sides of the body region than in a portion of the body region that is spaced apart from the first border sides.
