Production of a layer made from ferroelectric material used in the production of a ferroelectric capacitor comprises roughening a ferroelectric material layer on a surface and applying an electrode to the roughened surface

摘要

Production of a layer made from ferroelectric material with electrodes (1) comprises roughening a layer (7) of ferroelectric material on a surface and applying an electrode to the roughened surface or roughening a surface of an electrode and depositing a layer of ferroelectric material on the roughened surface. An independent claim is also included for a layer of ferroelectric material with an applied electrode.
