  • Patent number: 10103218
    Abstract: A metal-insulator-metal capacitor (MIM cap) includes a dielectric layer disposed over a substrate three contacts. A stacked structure of first and second metal layers separated by high-k dielectrics is disposed over the substrate and contacts. Three vias are formed through the structure to expose each of the three contacts. Selective etching is used to create gaps between the various metal layers at the location of the vias and these gaps are filled with an insulator. The vias are then filled with metal and the MIM cap is constructed such that the metal of the first via is electrically connected to the second metal layers and the metal of the second via is electrically connected to the first metal layers.
