Method for forming ferroelectric film and semiconductor device

摘要

In a method for forming a ferroelectric film of insulating metal oxide on a surface of an electrode with a concave or a convex or in convex shape which is formed above a substrate, multiple types of source gases constituting a material gas and each containing an organometallic compound are introduced into a chamber and main components of the multiple types of source gases are allowed to chemically react with one another with the chemical reaction proceeding depending on the reaction rate. Then, the ferroelectric film is deposited on the surface of the electrode.
