Abstract: A method used in forming an electronic component comprising conductive material and ferroelectric material comprises forming a non-ferroelectric metal oxide-comprising insulator material over a substrate. A composite stack comprising at least two different composition non-ferroelectric metal oxides is formed over the substrate. The composite stack has an overall conductivity of at least 1×102 Siemens/cm. The composite stack is used to render the non-ferroelectric metal oxide-comprising insulator material to be ferroelectric. Conductive material is formed over the composite stack and the insulator material. Ferroelectric capacitors and ferroelectric field effect transistors independent of method of manufacture are also disclosed.

Abstract: The hybrid memory device may include volatile and non-volatile memory cells on a single substrate, or die. The non-volatile memory cells may have ferroelectric capacitors and the volatile memory cells may have paraelectric or linear dielectric capacitors for their respective logic storage components. In some examples, the volatile memory cells may be used as a cache for the non-volatile memory cells. Or the non-volatile memory cells may be used as a back-up for the volatile memory cells. By placing both types of cells on a single die, rather than separate dies, various performance metrics may be improved, including those related to power consumption and operation speed.

Abstract: Methods, systems, and devices for formation for memory cells are described. A semiconductor device (e.g., a memory die) may include asymmetrical rows of conductive pillars and one or more dielectric materials. For example, the memory die may include a set of conductive pillars that are arranged in rows that are asymmetrically spaced. Here, a first row of conductive pillars may be a first distance away from a second row of conductive pillars and a second, larger distance away from a third row of conductive pillars. Additionally, the memory die may include one or more dielectric materials. In some cases, when depositing a dielectric material as part of a self-aligning process, the material may conformally line exposed surfaces according to a substantially uniform depth, which may decrease a subsequent quantity of masking operations to form the memory die.
