Claim Text:
1. An orthogonal finger capacitor comprising: a cathode bone frame having a cathode spine that extends along a longitudinal axis and having a cathode rib that is connected to the cathode spine and extends a cathode rib length from the cathode spine in a first direction, the first direction being transverse to the longitudinal axis; a set of cathode fingers that is connected to the cathode spine and extends, in the first direction, from the cathode spine, the cathode spine having a cathode spine width, the cathode rib having a cathode rib width, and cathode fingers in the set of cathode fingers having a cathode finger width, the cathode spine width being greater than the cathode finger width, and the cathode rib width being greater than the cathode finger width; an anode bone frame having an anode spine that extends parallel to the longitudinal axis and having an anode rib that is connected to the anode spine and extends from the anode spine in the first direction, the anode spine being spaced a distance, in the first direction, from the cathode spine, the distance being greater than the cathode rib length; a set of anode fingers that is connected to the anode spine and extends in a second direction from the anode spine and is interdigitated with the set of cathode fingers, the second direction being opposite the first direction, the anode spine having an anode spine width, and the anode rib having an anode rib width and an anode rib length, anode fingers in the set of anode fingers having an anode finger width, the anode spine width being greater than the anode finger width, and the anode rib width being greater than the anode finger width, the anode bone frame, the set of anode fingers, the cathode bone frame and the set of cathode fingers being located in a metal layer; an insulating dielectric on the anode bone frame, the set of anode fingers, the cathode bone frame, and the set of cathode fingers; an overlaying anode bone frame, in an overlaying metal layer above the insulating dielectric and the metal layer, having an overlaying anode spine and an overlaying anode rib, at least a segment of the overlaying anode rib extending above and in alignment with the anode spine, and at least a segment of the overlaying anode spine extending above and in alignment with the anode rib; and an anode via, configured to couple the anode bone frame to the overlaying anode bone frame, the anode via having an anode via width, the anode via width being concurrently greater than the anode finger width, less than the anode spine width, and less than the anode rib width.
