Abstract
A manufacturing method for a semiconductor device includes forming a dielectric film on a semiconductor substrate or on a lower electrode that is formed on a semiconductor substrate, attaching a metal to a predetermined area on a surface of the dielectric film selectively, forming a metal oxide film with an insulation property in the predetermined area on the surface of the dielectric film by applying heat treatment to the metal, and forming an upper electrode on the dielectric film in a state where the metal oxide film is formed in the predetermined area on the surface of the dielectric film.
