Abstract:
1. A method of manufacturing patterned ferroelectric media having a plurality of ferroelectric features, the method comprising: forming an electrode on a substrate; producing a precursor at a temperature lower than 500° C. so as to produce a precursor material; forming precursor features having a pattern corresponding to the formation of said ferroelectric features on the electrode, said precursor features being transformed into the ferroelectric features; and reacting a source material with the patterned precursor features to transform the precursor features into ferroelectric features, wherein the reaction between the source material and the precursor features occurs while the source material is being supplied, the transformation of the precursor features is governed by internal diffusion and internal nucleation of the source material to provide said ferroelectric features, and the reaction is a pulsed reaction whereby the source material is periodically reduced.
