Abstract: Dielectric films for semiconductor devices and methods of forming. A processing method includes forming a first film of a first dielectric material on a substrate by performing a first plurality of cycles of atomic layer deposition and, thereafter, heat-treating the first film, where a thickness of the first film is below a threshold thickness needed for spontaneous polarization in the first dielectric material.
