Abstract
A method for manufacturing a ferroelectric memory includes the steps of: forming an iridium film above a substrate; forming an iridium oxide layer on the iridium film; changing the iridium oxide layer into an amorphous iridium layer; oxidizing the amorphous iridium layer to form an iridium oxide portion; forming a ferroelectric film on the iridium oxide portion by a MOCVD method; and forming an electrode on the ferroelectric film.
