  • Patent number: 11710764
    Abstract: An integrated circuit (IC) including a semiconductor surface layer of a substrate including functional circuitry having circuit elements formed in the semiconductor surface layer configured together with a Metal-Insulator-Metal capacitor (MIM) capacitor on the semiconductor surface layer for realizing at least one circuit function. The MIM capacitor includes a multilevel bottom capacitor plate having an upper top surface, a lower top surface, and sidewall surfaces that connect the upper and lower top surfaces (e.g., a bottom plate layer on a three-dimensional (3D) layer or the bottom capacitor plate being a 3D bottom capacitor plate). At least one capacitor dielectric layer is on the bottom capacitor plate. A top capacitor plate is on the capacitor dielectric layer, and there are contacts through a pre-metal dielectric layer to contact the top capacitor plate and the bottom capacitor plate.

  • Patent number: 9496327
    Abstract: A process of forming an integrated circuit forms a high precision capacitor bottom plate with a metallic surface and performs a plasma treatment of the metallic surface. A high precision capacitor dielectric is formed by depositing a first layer of the capacitor dielectric on the high precision capacitor bottom plate wherein the first layer is silicon nitride, depositing a second layer of the capacitor dielectric on the first layer wherein the second portion is silicon dioxide, and depositing a third layer of the capacitor dielectric on the second portion wherein the third layer is silicon nitride. Plasma treatments may also be performed on the layers of capacitor dielectric pre- and/or post-deposition. A metallic high precision capacitor top plate is formed on the high precision capacitor dielectric.
