Abstract
Systems and methods are provided for fabricating a thin film capacitor involving depositing an electrode layer of conductive material on top of a substrate material, depositing a first layer of ferroelectric material on top of the substrate material using a metal organic deposition or chemical solution deposition process, depositing a second layer of ferroelectric material on top of the first layer using a high temperature sputter process and depositing a metal interconnect layer to provide electric connections to layers of the capacitor.
