Ferroelectric transistor, use thereof in a memory cell confuguration and method of producing the ferroelectric transistor

摘要

A ferroelectric transistor suitable as a memory element has a first gate intermediate layer and a first gate electrode disposed on the surface of a semiconductor substrate and disposed between source/drain regions. The first gate intermediate layer contains at least one ferroelectric layer. In addition to the first gate intermediate layer, a second gate intermediate layer and a second gate electrode are configured between the source/drain regions. The second gate intermediate layer contains a dielectric layer. The first gate electrode and the second gate electrode are connected to each other via a diode structure.
