    摘要: Unfavorable interactions of ferroelectric dielectric layers with silicon, intermetallic dielectrics, and other materials in metal-oxide semiconductor devices have discouraged the use of ferroelectric memory devices. This invention provides a zirconium titanate barrier layer with high insulating and low leakage characteristics. The barrier layer is not reactive with silicon or other materials used in metal-ferroelectric-semiconductor devices. These thermally stable layers should facilitate the integration of ferroelectric materials into memory and other semiconductor devices.

    摘要: A means to minimize physical distortion and modifications in the electrical properties of ferroelectric films incorporated into semiconductor devices is proposed. By introducing crystallographic texture into these ferroelectric films, the piezoelectric coefficient of the material can be minimized, reducing the interaction between a voltage across and mechanical stress on the film. In addition to having low piezoelectric coefficients, rhombohedral lead zirconate titanate films oriented along (111) exhibit low coercive fields and high remnant polarization, increasing their usefulness in layered semiconductor devices.
