Definitions
- the present invention relates to a plasma atomic layer growth method and apparatus in which plasma is used for atomic layer growth for forming a thin film in units of atomic layers and molecular layers.
- Atomic Layer Deposition has been developed as a technique that can form a very thin film with good step coverage and good uniformity (Reference 1: Japanese Patent Laid-Open No. 1 1794). No. 23, Reference 2: Japanese Patent Laid-Open No. 5-160152).
- Atomic layer growth is a technique for forming a thin film in atomic layer units by alternately supplying a raw material for each element constituting the film to be formed to a substrate. In the atomic layer growth method, only one layer or n layer is adsorbed on the surface while the raw materials for each element are being supplied, so that excess raw materials do not contribute to the growth. This is called self-stopping action of growth.
- the atomic layer growth method it has high shape adaptability and film thickness controllability as well as a general CVD (Chemical Vapor Deposition) method. Practical application to the formation of an insulating film called is expected. In addition, since an insulating film can be formed at a low temperature of about 300 ° C., application to the formation of a gate insulating film in a thin film transistor of a display device using a glass substrate is expected.
- CVD Chemical Vapor Deposition
- the atomic layer growth method for example, when forming a metal oxide film (metal nitride film), two types of gases, a metal source gas and an oxidizing gas (nitriding gas), are used alternately. Introducing and exhausting are repeated. For this reason, the atomic layer growth method has a smaller film thickness per unit time compared to a general CVD method in which a film is deposited by continuously introducing a gas. There is a problem that is slow.
- the present invention has been made to solve the above-described problems, and it is possible to improve the deposition rate by atomic layer growth using plasma in a state where the occurrence of damage is suppressed.
- the purpose is to make it.
- a source gas such as an organic compound is supplied to the surface of a heated substrate inside a film forming chamber in which a monopole antenna is disposed, so that the organic compound is A first step in which an adsorption layer adsorbed on the surface of the substrate is formed; a second step in which the source gas is removed from the inside of the deposition chamber after the supply of the source gas is stopped; A reactive gas containing a reactive substance is introduced inside, a high frequency is supplied to the monopole antenna to generate a reactive gas plasma to generate an atomic substance, and the atomic substance reacts with the adsorption layer to form a substrate. And at least a third step in which a compound layer in which a reactant reacts with the adsorption layer is formed on the adsorption layer.
- the reactant is selected from oxygen and nitrogen.
- a source gas made of an organic compound is supplied to the surface of a heated substrate, and an adsorption layer in which the organic compound is adsorbed on the surface of the substrate is formed.
- the first step of forming the state the second step of removing the source gas from the inside of the film forming chamber after the supply of the source gas is stopped, and the introduction of the oxidizing gas containing oxygen into the inside of the film forming chamber.
- a high frequency is supplied to the monopole antenna to generate an oxygen gas plasma to generate atomic oxygen, and the adsorption layer is oxidized by the atomic oxygen to form an oxide layer on the substrate.
- at least a third step for achieving the above state In this case, oxidation is caused by atomic oxygen, which is considered to be more reactive than ozone. Done.
- a raw material gas having an organic compound force is supplied to the surface of the heated substrate to form an adsorption layer in which the organic compound is adsorbed on the surface of the substrate.
