Abstract
A semiconductor device that provides a pad electrically connected to the metal layer and a capacitor connected to the pad is disclosed. The semiconductor device provides an insulating film between the lower electrode of the capacitor and the pad. Because the insulating film protects and isolates the lower electrode from etching of the substrate via and deposition of the via metal, the lower electrode avoids voids or vacancies during formation of the via and the via metal.
