SEMICONDUCTOR DEVICE INCLUDING CAPACITOR HAVING IMPROVED STRUCTURAL STABILITY AND IMPROVED CAPACITANCE, AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor device including a capacitor having improved structural stability and improved capacitance, and to provide a method for manufacturing the device.

SOLUTION: The capacitor includes a cylinder-type storage electrode; a dielectric film formed on the storage electrode; a plate electrode formed on the dielectric film; and a ring-type structure which is formed on an upper part of the storage electrode, and has a diameter which is expanded upwardly. Adjacent storage electrodes are supported by each other via a stabilizing member through the ring-type structure, thereby the structural stability of the capacitor is significantly improved.
