Abstract

The capacitor is a thin-film capacitor comprising two metal electrodes separated by a dielectric. The dielectric is formed by superposition of at least two sub-layers of preferably perovskite-based dielectric material. Two adjacent superposed dielectric sub-layers are separated by an electrically insulated metal intermediate layer, for example made of platinum. Using very thin dielectric sub-layers, preferably with a thickness of less than 20 nm, separated from one another by metal intermediate layers enables the increase of the breakdown field and the reduction of the leakage currents linked to a reduction of the thickness of the dielectric to be transposed to the level of the capacitor, while preserving a reasonable working field.
