Patent ID: 7291505

Claim:
A method of manufacturing a ferroelectric device wherein a body is formed that comprises a substrate, and the device is provided with a ferroelectric layer having a connection conductor on a side facing away from the substrate, an oxygen-free ferroelectric material being selected as the material for the ferroelectric layer which is used to form an active electrical element, forming a field effect transistor in the substrate, the field effect transistor having a source region, a drain region and a gate electrode, applying a barrier layer directly to the source region or the drain region, applying a conductive layer directly to the baffler layer, characterized in that the conductive layer is provided between the substrate and the ferroelectric layer, and the conductive layer forms a further connection conductor of the ferroelectric layer, and the active electrical element is obtained by forming a Schottky junction between the ferroelectric layer and at least one of the connection conductors.
