US Patent 11751400 Embedded ferroelectric memory in high-k first technology

In some embodiments, the present disclosure relates to an integrated circuit. The integrated circuit has a first doped region and a second doped region within a substrate. A ferroelectric material is arranged over the substrate and laterally between the first doped region and the second doped region. A conductive electrode is over the ferroelectric material and between sidewalls of the ferroelectric material. One or more sidewall spacers are arranged along opposing sides of the ferroelectric material. A dielectric layer continuously and laterally extends from directly below the one or more sidewall spacers to directly below the ferroelectric material.
