ABSTRACT:
A ferroelectric memory device is fabricated while mitigating edge degradation. A bottom electrode is formed over one or more semiconductor layers. A ferroelectric layer is formed over the bottom electrode. A top electrode is formed over the ferroelectric layer. The top electrode, the ferroelectric layer, and the bottom electrode are patterned or etched. A dry clean is performed that mitigates edge degradation. A wet etch/clean is then performed.
