Abstract
An energy storage device such as a metal-insulator-metal capacitor and a method for manufacturing the energy storage device. The metal-insulator-metal capacitor includes an insulating material positioned between a bottom electrode or bottom plate and a top electrode or top plate. The surface area of the bottom electrode is greater than the surface area of the insulating material and the surface area of the insulating material is greater than the surface area of the top electrode. The top electrode and the insulating layer have edges that are laterally within and spaced apart from edges of the bottom electrode. A protective layer covers the top electrode, the edges of the top electrode, and the portions of the insulating layer that are uncovered by the top electrode. The protective layer serves as an etch mask during the formation of the bottom electrode.
