Original Abstract Submitted
various embodiments of the present disclosure are directed towards a ferroelectric memory device comprising a chimney seed structure. a ferroelectric layer overlies a bottom electrode layer, and a top electrode layer overlies the ferroelectric layer. the top electrode layer, the ferroelectric layer, and the bottom electrode layer form a plurality of memory cells, and a dielectric wall extends through the top electrode layer and segments the top electrode layer into a plurality top electrodes individual to the memory cells. the chimney seed structure underlies the ferroelectric layer and extends through the bottom electrode layer from the ferroelectric layer. the chimney seed structure is configured to seed ferroelectric crystalline growth in the ferroelectric layer to allow the ferroelectric layer to achieve a large remanent polarization with a small thickness. the small thickness increases read speeds, while the large remanent polarization increases a read window and hence reliability.
