摘要:
An Integrated Circuit (IC) chip with one or more vertical plate capacitors, each vertical plate capacitor connected to circuits on the IC chip and a method of making the chip capacitors. The vertical plate capacitors are formed with base plate pattern (e.g., damascene copper) on a circuit layer and at least one upper plate layer (e.g., dual damascene copper) above, connected to and substantially identical with the base plate pattern. A vertical pair of capacitor plates are formed by the plate layer and base plate. Capacitor dielectric between the vertical pair of capacitor plates is, at least in part, a high-k dielectric.
