Abstract

A method of fabricating a ferroelectric capacitor is disclosed. The method comprises the decreases a reduction in a bottom electrode material during formation of the ferroelectric dielectric portion of the capacitor. In the above manner, a fatigue resistance of the ferroelectric capacitor is increased substantially.
