Abstract:
Roughness is eliminated and planarization is achieved by a metal oxide film on a surface of a lower electrode. Consequently, damage on a capacitive film caused by the roughness of the lower electrode is reduced. Furthermore, physical damage on the capacitive film is reduced by forming a first layer of an upper electrode by, for example, CVD. Consequently, the damage on the capacitive film is suppressed, and the reliability of the capacitive film is improved. Furthermore, not by forming the whole upper electrode by the CVD or the like, but by forming a second layer by PCD or the like on the first layer, an increase in resistance of the upper electrode is suppressed as well.

Claim (Index 1):
A method for manufacturing a semiconductor device having a capacitor with a Metal-Insulator-Metal structure, the method comprising:\n forming a first electrode; forming a capacitive film on the first electrode, the capacitive film in contact with the first electrode; and forming a second electrode on the capacitive film, the second electrode in contact with the capacitive film, wherein, in the forming of the second electrode, a first layer is formed on a surface of the capacitive film through chemical vapor deposition, atomic layer deposition, or metal organic chemical vapor deposition, wherein, in the forming of the second electrode, a second layer is formed on the first layer through physical vapor deposition, wherein, in the forming of the first electrode, a metal oxide film is formed at one surface of the first electrode facing the capacitive film, wherein two capacitors each with the Metal-Insulator-Metal structure and each configured by the first electrode, the capacitive film and the second electrode are provided, and wherein the two capacitors are connected in a reverse connection by\n electrically connecting the second electrode of one of the two capacitors to the first electrode of the other one of the two capacitors, and \n electrically connecting the first electrode of the one of the two capacitors to the second electrode of the other one of the two capacitors.
