Abstract
A MIM capacitor including a bottom metal layer on a substrate, a first contact window in the bottom metal layer; and a first dielectric spacer disposed within the first contact window on vertical sidewalls of the bottom metal layer, where the first dielectric spacer has a rounded upper surface, where a bottom most surface of the bottom metal layer is substantially flush with a bottom most surface of the first insulator layer. A method including forming a bottom metal layer on a substrate, forming a first contact window in the bottom metal layer, and forming a first dielectric spacer disposed within the first contact window on vertical sidewalls of the bottom metal layer, wherein the first dielectric spacer has a rounded upper surface.
