Abstract
Forming a vertically stacked interdigitated metal-insulator-metal capacitor includes forming a first set of connecting vias within a first dielectric layer disposed above a semiconductor substrate followed by deposition of a first conductive material above the first dielectric layer, the first conductive material fills the first set of connecting vias. A top portion of the first conductive material is patterned to form a first set of interdigitated electrodes. A remaining portion of the first conductive material below the first set of interdigitated electrodes includes a first metal plate. An insulating layer is conformally deposited above the first conductive material for electrically separating the first set of interdigitated electrodes and the first metal plate.
