Abstract: A method for forming a capacitor stack is described. In some embodiments of the present invention, a first electrode structure is comprised of multiple materials. A first material is formed above the substrate. A portion of the first material is etched. A second material is formed above the first material. A portion of the second material is etched. Optionally, the first electrode structure receives an anneal treatment. A dielectric material is formed above the first electrode structure. Optionally, the dielectric material receives an anneal treatment. A second electrode material is formed above the dielectric material. Typically, the capacitor stack receives an anneal treatment.
