  • Publication number: 20200176557
    Abstract: Methods of forming a 3-dimensional metal-insulator-metal super high density (3D-MIM-SHD) capacitor and semiconductor device are disclosed herein. A method includes depositing a base layer of a first dielectric material over a semiconductor substrate and etching a series of recesses in the base layer. Once the series of recesses have been etched into the base layer, a series of conductive layers and dielectric layers may be deposited within the series of recesses to form a three dimensional corrugated stack of conductive layers separated by the dielectric layers. A first contact plug may be formed through a middle conductive layer of the corrugated stack and a second contact plug may be formed through a top conductive layer and a bottom conductive layer of the corrugated stack. The contact plugs electrically couple the conductive layers to one or more active devices of the semiconductor substrate.
