Claim 16:
17. An integrated circuit device comprising a capacitor structure, wherein the capacitor structure includes:
a bottom electrode on a substrate;
a supporter on the bottom electrode;
a dielectric layer on the bottom electrode; and
a top electrode on the dielectric layer,, wherein the bottom electrode includes:
a base electrode layer including a top surface, a first side surface and a second side surface that is adjacent to the first side surface; and
a conductive capping layer including niobium nitride, and covering the first side surface and the top surface of the base electrode layer,
wherein the supporter covers the second side surface of the base electrode layer of the bottom electrode, and
wherein the dielectric layer is not in direct contact with the top surface, the first side surface, and the second side surface of the base electrode layer of the bottom electrode.
