Methods for producing a thin film ferroelectric device using a two-step temperature process on an organic polymeric ferroelectric precursor material stacked between two conductive materials

A method for producing a thin film ferroelectric device, the method comprising:

• (a) depositing an organic polymeric ferroelectric precursor material onto a first conductive material such that the organic polymeric ferroelectric precursor material has a first surface and an opposing second surface, wherein the first surface of the organic polymeric ferroelectric precursor material is in contact with the first conductive material;
• (b) depositing a second conductive material on the second surface of the organic polymeric ferroelectric precursor material to form a stack, wherein the organic polymeric ferroelectric precursor material is positioned at least partially between the first and second conductive materials;
• (c) subjecting the stack to a first temperature above a melting temperature of the organic polymeric ferroelectric precursor material to form an organic polymeric ferroelectric material having ferroelectric hysteresis properties;
• and
• (d) subjecting the stack to a second temperature below the melting temperature of the organic polymeric ferroelectric precursor material to densify the organic polymeric ferroelectric material and to obtain a thin film ferroelectric device.
