摘要:
A method of manufacturing a ferroelectric capacitor. In this method, a lower electrode is formed on a base at first. A ferroelectric film which includes a PZTN complex oxide including lead, zirconium, titanium, and niobium on the lower electrode is formed, and then an upper electrode is formed on the ferroelectric film. A protective film is then formed to cover the lower electrode, the ferroelectric film, and the upper electrode, and heat treatment for crystallizing the PZTN complex oxide is performed at least after forming the protective film.

A method of manufacturing a ferroelectric film includes crystallizing a raw material having a complex oxide, the method including: performing a heat treatment in a first condition in which a predetermined pressure and a predetermined temperature are applied; and maintaining a second condition, in which a pressure and a temperature lower than the pressure and the temperature in the first condition are applied, after the heat treatment in the first condition, and the raw material is crystallized by repeating the heat treatment in the first condition and the maintaining the second condition.
摘要:
The present invention relates to a method of manufacturing an electrode which includes forming an electrode over a substrate. Initial crystal nuclei of an electrode material are formed over the substrate in an island pattern, and then grown layers of the electrode material are formed by causing the initial crystal nuclei to be grown. A substrate temperature when forming the initial crystal nuclei is higher than a substrate temperature when forming the grown layers.

摘要:
A method of manufacturing a ceramic film includes forming the ceramic film by crystallizing a ceramic raw material liquid which includes a first raw material liquid and a second raw material liquid. The first raw material liquid and the second raw material liquid are different types of liquids, the first raw material liquid is a raw material liquid for producing a ferroelectric, the second raw material liquid is a raw material liquid for producing an oxide such as an ABO-type oxide, a solvent included in the first raw material liquid and a solvent included in the second raw material liquid have different polarities, and the ceramic film is formed in a state in which the first raw material liquid and the second raw material liquid are phase separated so that first crystals formed of the first raw material liquid are intermittently formed in a surface direction of the ceramic film and second crystals formed of the second raw material liquid are formed so as to interpose between the first crystals.
