Abstract

Disclosed is a non-volatile, ferroelectric random access memory (F-RAM) device and a method for fabricating a damascene self-aligned F-RAM that allows for the formation of a ferroelectric capacitor with separated PZT layers aligned with a preexisting, three dimensional (3-D) transistor structure.
