Abstract
An interlayer insulating film is formed on a semiconductor substrate on which a transistor has been formed, and an adhesion layer made from a metal oxide not oriented is formed on the interlayer insulating film. A capacitor composed of a lower electrode, a capacitor dielectric film made from a high dielectric constant material or a ferroelectric material and an upper electrode successively formed in this order above the semiconductor substrate is provided on the adhesion layer. A conducting plug for electrically connecting the transistor and the capacitor to each other is provided in the interlayer insulating film and the adhesion layer.
