Abstract:
1. A capacitor comprising: a substrate; a plurality of back-end-of line (BEOL) layers disposed above the substrate; a first set of electrodes extending from a first common hub, wherein each electrode of the first set extends through at least one of the plurality of BEOL layers; a second set of electrodes extending from a second common hub, wherein each electrode of the second set extends through at least one of the BEOL layers, wherein the second set of electrodes extends at a depth through the plurality of BEOL layers that differs from the depth that the first set of electrodes extends through the plurality of BEOL layers; and wherein a BEOL layer from the plurality of BEOL layers that is closest to the substrate includes fewer electrodes from the first set of electrodes and the second set of electrodes than at least one BEOL layer above that is farther from the substrate, and wherein each BEOL layer from the plurality of BEOL layers includes more electrodes from the first set of electrodes and the second set of electrodes than a BEOL layer therebelow, and wherein the first set of electrodes has at least one electrode vertically and horizontally interspersed between at least two electrodes of the second set of electrodes.
