Abstract
An example of a capacitor includes a series of ridges and trenches and an interconnect region on the integrated circuit substrate. The series of ridges and trenches and the interconnect region have a capacitor foundation surface with a serpentine cross-sectional shape on the series of ridges and trenches. Electrical conductors are electrically connected to the electrode layers from the interconnect region for access to the electrode layers of the capacitor assembly.
