Voltage-controllable capacitor comprising a ferroelectric layer and method for producing the voltage-controllable capacitor comprising a ferroelectric layer

摘要

The present invention relates to a voltage-controllable capacitor comprising a first electrode layer (4) composed of a non-ferroelectric material, said first electrode layer being applied on a substrate (6), a ferroelectric interlayer (3) having a thickness that is less than the thickness of the first electrode layer (4), and a second electrode layer (2) composed of a non-ferroelectric material. The ferroelectric interlayer (3) is arranged between the first electrode layer (4) and the second electrode layer (2).
