Abstract
The invention relates to a field-effect transistor having a drain region, a source region and a gate electrode for influencing a channel area. The invention consists of arranging the source region and the gate electrode one above the other in a projection onto the channel plane such that the effective length is so small that an increase of the electron velocity in the channel is achieved.
