Patent ID: 6924519

Claim:
A semiconductor device comprising: a semiconductor substrate; and a capacitor provided above the semiconductor substrate and comprising a bottom electrode, a top electrode, and a dielectric film provided between the bottom electrode and the top electrode, at least one of the bottom electrode and the top electrode comprising: a conductive film selected from a noble metal film and a noble metal oxide film; a metal oxide film having a perovskite structure, provided between the dielectric film and the conductive film, represented by ABO 3 , and containing a first metal element as a B site element; and a metal film provided between the conductive film and the metal oxide film, and containing a second metal element which is a B site element of a metal oxide having a perovskite structure, a decrease of Gibbs free energy at a time when the second metal element forms an oxide being larger than that at a time when the first metal element forms an oxide.
