SEMICONDUCTOR DEVICE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor device having a capacitor capable of assuring a prescribed electrostatic capacity and simultaneously reducing in size, and a method for manufacturing the same. SOLUTION: The semiconductor device comprises a capacitor lower electrode 3a having an upper surface and a metal film, a dielectric film 4a disposed on the upper surface of the electrode 3a and having a thickness smaller than that of the electrode 3a, and a capacitor upper electrode 6a disposed on the film 4a and having a width narrower than that of the electrode 3a and a metal film.
