Abstract: An antiferroelectric field effect transistor (Anti-FeFET) of a memory cell includes an antiferroelectric layer instead of a ferroelectric layer. The antiferroelectric layer may operate based on a programmed state and an erased state in which the antiferroelectric layer is in a fully polarized alignment and a non-polarized alignment (or a random state of polarization), respectively. This enables the antiferroelectric layer in the FeFET to provide a sharper/larger voltage drop for an erase operation of the FeFET (e.g., in which the FeFET switches or transitions from the programmed state to the erased state) relative to a ferroelectric material layer that operates based on switching between two opposing fully polarized states.

Additionally, or alternatively, the inert metal material may have a grain size that is greater relative to a grain size of an inert metal material deposited using the physical vapor deposition tool without the magnet component, the single cathode, and the power circuit.
