Abstract:
A first source-drain region, a channel region, and a second source-drain region are arranged one after another in a semiconductor substrate. At least the surface of the channel region and parts of the first source-drain region are covered by a dielectric layer. A ferroelectric layer is disposed on the surface of the dielectric layer between two polarization electrodes. A gate electrode is arranged on the surface of the dielectric layer. The thickness of the dielectric layer is dimensioned such that a remanent polarization of the ferroelectric layer, which is aligned between the two polarization electrodes, produces compensation charges in part of the channel region. The ferroelectric transistor is suitable as a memory cell for a memory cell configuration.

Abstract:
The invention relates to a ferroelectric transistor comprising two source/drain regions (13) and a channel region arranged therebetween on a semiconductor substrate (11). A first dielectric intermediate layer (14) is located on the surface of the channel region and said layer contains Al2O3.
