Abstract
An integrated circuit device includes a substrate having an active region, a conductive landing pad at a first vertical level above the substrate and connected to the active region, a capacitor including a lower electrode at a second vertical level higher than the first vertical level above the substrate, and a conductive multifunction plug including an extended landing pad portion at a third vertical level between the first vertical level and the second vertical level and contacting the conductive landing pad, and an extended lower electrode portion integrally connected to the extended landing pad portion and contacting the lower electrode. The capacitor further includes a dielectric layer covering a surface of the lower electrode and the extended lower electrode portion of the conductive multifunction plug.
