Abstract
An embodiment high-density capacitor includes a bottom electrode having a plurality of non-concentric cylindrical portions, a top electrode including a plurality of vertical portions and a surrounding portion, and a dielectric layer separating the top electrode from the bottom electrode. Each of the plurality of non-concentric cylindrical portions includes an inner shell and an outer shell and each of the plurality of vertical portions is vertically surrounded by the inner shell of a respective cylindrical portion of the bottom electrode. The surrounding portion of the top electrode respectively vertically surrounds each of the plurality of non-concentric cylindrical portions of the bottom electrode such that adjacent non-concentric cylindrical portions of the bottom electrode are separated from one another by the surrounding portion of the top electrode. At least some of the plurality of non-concentric cylindrical portions of the bottom electrode include a spatial distribution having a hexagonal symmetry.
