Abstract
A capacitor includes cup-shaped lower electrodes disposed on a substrate, a capacitor dielectric layer conformally covering inner surfaces and outer surfaces of the cup-shaped lower electrodes, and a support layer disposed between outer surfaces of the cup-shaped lower electrodes to connect the cup-shaped lower electrodes. The capacitor further includes an annealed oxide layer, which is interposed between the inner surfaces of the cup-shaped lower electrodes and the capacitor dielectric layer, and is also interposed between a portion of the outer surfaces of the cup-shaped lower electrodes and the capacitor dielectric layer. A method for forming the capacitor is also provided.
