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.

Semiconductor device including a high density MIM capacitor and method

A method for manufacturing the integrated circuit device comprises providing a substrate having a first region, a second region, and a third region. A first dielectric layer is formed in the first region of the substrate. A second dielectric layer is formed in the second region and the third region. A sacrificial layer is formed over the first dielectric layer and the second dielectric layer. The sacrificial layer, the first dielectric layer, and the second dielectric layer are patterned to form a first gate stack, a second gate stack, and a third gate stack. An interlayer dielectric (ILD) layer is formed in between the first gate stack, the second gate stack, and the third gate stack. The second gate stack is removed to form an opening adjacent to the ILD layer and a third dielectric layer is formed in the opening.
