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.Type: GrantFiled: June 27, 2018Date of Patent: July 25, 2023Assignee: Texas Instruments IncorporatedInventors: Poornika Fernandes, Sagnik Dey, Luigi Colombo, Haowen Bu, Scott Robert Summerfelt, Mark Robert Visokay, John Paul Campbell
