    摘要: An integrated circuit device with capacitors and methods of forming the integrated circuit device are provided. The methods may include forming a first lower capacitor electrode pattern on an inner surface of a hole in a mold layer. The first lower capacitor electrode pattern may have a hollow cylindrical shape and an opening in an upper surface. The method may further include forming a second lower capacitor electrode pattern plugging the opening and an upper surface of the second lower capacitor electrode pattern may be planar. The first and the second lower capacitor electrode patterns may comprise a lower capacitor electrode including a void. Additionally, the method may include removing the mold layer to expose the lower capacitor electrode, forming a dielectric layer on the lower capacitor electrode, and forming an upper capacitor electrode layer on the dielectric layer.
