Abstract
A high capacitance embedded capacitor and associated fabrication processes are disclosed for fabricating a capacitor stack in a multi-layer stack to include a first capacitor plate conductor formed with a cylinder-shaped storage node electrode formed in the multi-layer stack, a capacitor dielectric layer surrounding the cylinder-shaped storage node electrode, and a second capacitor plate conductor formed from a conductive layer in the multi-layer stack that is sandwiched between a bottom and top dielectric layer, where the cylinder-shaped storage node electrode is surrounded by and extends through the conductive layer.
