<p>A method of manufacturing a patterned ferroelectric polymer memory medium is disclosed, which includes forming an electrode on a substrate; forming a ferroelectric polymer thin film on the electrode; and patterning and orienting the polymer thin film into a plurality of nanostructures by embossing techniques. Also disclosed are two methods which include forming nanofeatures in an interlayer dielectric (ILD) layer deposited on a substrate; forming a ferroelectric polymer thin film on the ILD layer in the nanofeatures; and patterning and orienting the polymer thin film into a plurality of nanostructures by pressing. The patterning process followed by an annealing process promotes specific crystal orientation, which significantly reduces the operation voltage, and increases the signal-to-noise ratio. The invention also covers devices made of a ferroelectric polymer layer oriented by such an embossing method and the use of such devices at a coercive field of 10 MV/m or less.</p> |
