Abstract
Integrated circuit (IC) devices include a metal-insulator-metal (MIM) capacitor having a top electrode plate, a bottom electrode plate, and a plurality of intermediate electrode plates between the top electrode plate and the bottom electrode plate. A plurality of dielectric layers may separate each of the electrode plates of the MIM capacitor from adjacent plates of the MIM capacitor. Each of the intermediate electrode plates may have a thickness that is greater than a thickness of the top electrode plate and the bottom electrode plate. By providing multiple intermediate electrode plates between the top and bottom electrode plates of the MIM capacitor, and allocating the greatest plate thicknesses to the intermediate plates, the capacitance density may be increased in a given area of the IC device, which may provide increased performance for the IC device.
