Abstract:
A method of forming a semiconductor device, the semiconductor device comprising a substrate, the method comprising:forming a first dielectric layer on the substrate; forming a first capacitor cavity in the first dielectric layer, wherein the substrate has an exposed surface within the capacitor cavity; forming a first capacitor electrode layer over along substantially all the exposed surface of the first dielectric layer; removing a portion of the first capacitor electrode layer to expose the upper surface of the first dielectric layer to form a first capacitor electrode in the capacitor cavity, wherein the first capacitor electrode lies along substantially all the exposed surface of the first dielectric layer; forming a capacitor dielectric layer after formino the first capacitor electrode layer, wherein at least a portion of each of the first capacitor electrode and the capacitor dielectric layer lies within the capacitor cavity; forming a second capacitor electrode layer over the capacitor dielectric layer; and patterning the second capacitor electrode layer to form a second capacitor electrode.
