Abstract
A capacitor may include at least one of a polysilicon layer over a semiconductor substrate; a capacitor dielectric layer over a polysilicon layer; an insulating layer over a capacitor dielectric layer; a metal layer connected to a capacitor dielectric layer through a first region of an insulating layer; an upper metal wiring layer connected to a metal layer over an insulating layer; and/or a lower metal wiring line layer connected to a polysilicon layer through a metal contact that passes through a second region of an insulating layer and a capacitor dielectric layer over the insulating layer.
